Sustainability and going green are key concerns across many different industries today. Many companies are looking for more ways to green their processes and become more eco-friendly. There are many ways to go green today, and numerous benefits to the environment, human health and a company’s bottom line. Using more environmentally friendly air compressors is one way companies can go green in their production lines, and today’s options are better than ever for the environment. Let’s take a closer look at what makes an air compressor more eco-friendly, how you can make your current air compressors more environmentally friendly and the benefits of greener air compressors.

Evolution of Green Air Compressors

Air compressors have been an essential part in the evolution of many different industrial processes. Everything from manufacturing to auto repair shops makes use of air compressors that power robotic arms, tools and more. Air compressors can power sanders, painters, dryers and other equipment used for jobs that had to be completed by hand in the past. These air-powered tools can complete a job much more quickly and with greater precision as well.

As many industries progressed over the years, companies looked for more ways to save money and increase efficiency in all of their processes. One of the easiest ways to accomplish this is to search for more eco-friendly options, including more efficient and environmentally friendly air compressors.

Today, sustainability is a key issue globally, and it’s no different for manufacturers of air compressors. New models of air compressors are more environmentally friendly than ever. Many of these new models utilize variable speed drives, which increase efficiency and save on energy. Other common factors of more eco-friendly air compressors include being completely oil-free for cleaner production of compressed air and adding electrification for mobile units.

The controls on many of these green air compressors are more sophisticated as well, with updated technology that can constantly optimize production processes. This, in turn, ensures that all other equipment is operating more efficiently and increases the whole system’s overall efficiency. Some systems even monitor faults and failures in the system, alerting workers when maintenance is needed and saving valuable time.

Benefits of Green Technology

The use of more eco-friendly technology like air compressors can have many benefits across many different industries. And the bigger the facility, the bigger the savings and environmental impact, even with just a few simple changes like upgraded, more efficient equipment. Using eco-friendly compressed air solutions contributes to the following benefits:

Energy Cost Savings Over Time

Green technology, like variable speed air compressors, uses less energy to run, which means a facility can save money in the long run with lower energy bills. Larger facilities can save even more on overall energy costs. In addition to the energy cost savings, new variable speed air compressors also have fewer issues with performance and maintenance over time. They can help your entire production line run more efficiently. This means less downtime and less money spent on maintenance too. All of these little savings can really add up, contributing to a lower operating cost for your whole facility.

Improved Air Quality

Many eco-friendly air compressors are oil-free, which means that they operate without any oil at all. These machines do not emit any polluting smoke or other waste gases that could harm the environment and compromise the health of those working in enclosed spaces. Oil-free compressors contribute to cleaner air inside the facility where they are used, as well as the surrounding environment.

No Oil Contamination

Traditional air compressors that use oil are always at risk of oil contamination. When this happens, valuable production time is lost, while labor costs increase to service the machine and production lines. A compressor must be fully serviced when this happens before it can resume production. Oil contamination can ruin products and slow down overall production times. However, with oil-free air compressors, oil contamination is not a concern, and production can keep running smoothly.

More Durable, Longer-Lasting Compressors

Traditional air compressors need frequent servicing, which can slow or shut down production and increase labor costs while the unit is serviced and repaired. A new variable speed air compressor, however, can last much longer, working day after day without needing service and maintenance. In fact, a variable speed compressor lasts on average 100,000 work hours before needing any kind of service. This usually amounts to several years of solid work from these machines before any maintenance is necessary. This also saves in maintenance costs and increases the overall production and efficiency of the facility.

Wider Range of Uses

More eco-friendly options like variable speed air compressors can be suited for a much wider range of purposes. Different tools and machines that use compressed air may require different pressurization demands. Variable speed compressors can handle the different demands of all of the machinery and processes in your facility and can be programmed to do so automatically. Each application of compressed air can have its own precise needs met.

Lower Noise Levels

If your facility already uses gas-powered air compressors, you know they can be quite noisy. This is because these types of compressors need to use an engine to produce compressed air. Most eco-friendly air compressors today use electricity as their power source, avoiding the need for a gas-powered engine. This means these air compressors can run much more quietly, contributing to safer noise levels in the workplace. Many newer models of air compressors also utilize thicker steel or aluminum walls for better sound dampening qualities, as well as sound-dampening enclosures and rubber components to help reduce noise.

Compliance With Governmental Standards

The Energy Policy and Conservation Act (EPCA) from 1975 sets standards for all sorts of products, equipment and machinery, including air compressors. Recently, the EPCA implemented new, more strict, energy standards for air compressors. These new measures were effective as of March 10, 2020, and compliance with the new rules will be required by January 10, 2025. Switching to newer, greener air compressors now means you’ll automatically be in compliance with the new laws and will not have to worry as the 2025 deadline approaches.

More Positive Public Image

Today’s consumers are more aware and concerned about environmental issues, and they are more likely to support companies that put more effort into reducing their environmental impact. Even for companies that do not serve customers directly, public image is very important. Using more eco-friendly air compressors is one of the best choices your company can make to go green. You can advertise your greening efforts, and your public image will absolutely benefit. You’ll enjoy more consumer support and a more positive public image the more eco-friendly changes you make as a company. You can become a leader in your industry and pioneer the future toward more eco-friendly practices.

Reduced Carbon Footprint

Switching to more eco-friendly air compressors can help your company leave a much smaller carbon footprint than you would otherwise. Using variable speed air compressors reduces emissions and decreases energy usage, which helps combat climate change and reduce the impact on the environment.

Strategies to Make Current Air Compressors Environmentally Friendly

If your company already uses air compressors, you can make your existing units more environmentally friendly. To reap all of the benefits from above, follow these tips to make your air compressors more eco-friendly:

Keep up With Maintenance

No matter what type of air compressors your facility utilizes, proper and regular maintenance is key. Traditional air compressors require air and water to operate, and if a unit is not operating efficiently, it can use a disproportionate amount of resources while performing at a lower level of efficiency and output. While you may not be able to completely mitigate these drains on resources and efficiency, especially if you have older air compressors in use, you can reduce the impact with proper maintenance.

To keep your air compressors running as smoothly as possible, ensure that your team performs regular maintenance checks. Ideally, your in-house staff should do checks twice a year, with additional yearly inspections from a trained and experienced repair professional. If you notice any issues during these maintenance checks, take care of them right away.

To further supplement the maintenance efforts, ensure that your employees have time built into their day for daily maintenance activities, like emptying drainage pans. Make sure your staff can complete these daily tasks without rushing through, so they can be taken care of with the proper amount of attention and care. Encourage your staff to report any issues or inconsistencies so you can do repairs before it’s a bigger problem.

Utilize Integrated Pest Control

All sorts of pests, including rodents, snakes and insects, are a common concern in many industrial businesses and can wreak havoc on machinery and equipment in any facility. Many businesses resort to harsh chemicals to keep pests at bay, but this can create a dangerous work environment for employees.

Integrated pest management goes beyond chemical treatments and involves strategic placement and construction of equipment to deter and prevent pest infestations. This includes controlling leaks coming from your air compressor, which can create an environment where insects and rodents like to live. Seal all leaks, and watch for holes anywhere in the system. Even tiny holes can be access points for insects in search of water. Make sure all vents and ductwork are properly covered.

When you use integrated pest management strategies, you reduce the need for dangerous chemicals that threaten the health of your employees and harm the surrounding environment. This is an easy way to help your facility go green.

Use Higher Quality Lubricants and Fluids

Many air compressor systems need some type of synthetic lubricant to run smoothly. However, if water escapes the air compressor unit, it may be contaminated with small amounts of these lubricating fluids. If water and fluids leak from your air compressor system, and they are not properly contained, they can eventually contaminate groundwater and nearby waterways. Incorrect use of the air compressor or damaged components can increase the risk of leaking lubricants and other fluids.

The first step towards greening this part of the system is to fix any leaks that you can. You should also attempt to contain any fluids coming out of your air compressor system. Any water and other fluids should be disposed of properly, not used to water plants or dumped down the drain. The residual lubricant fluids can contaminate municipal water, so this should be avoided. Don’t allow fluids to drip out of the system and just run off into floor drains.

The other important step is to switch to higher quality, more eco-friendly lubricants and fluids. Whenever possible, you should use fluids that are more sustainable and better for the environment. But even using a higher quality synthetic oil is better in the long run because it can help the air compressor system run more efficiently, meaning less wasted energy and maintenance costs. Using incorrect or lower quality fluids can damage the whole system over time, cause runoff and have a lower efficiency overall. These inferior fluids can leave behind buildup or cause corrosion inside the air compressor. Make sure you are using the best possible lubricants for your air compressor model.

Upgrade Your Air Compressors

Sometimes the best way to go green with your air compressors is to replace them completely. If your air compressors are old, and you find that they need frequent repairs, it may be time to consider replacements. Air compressors that constantly need repairs or frequently spring leaks can lead to all of the problems discussed above.

Newer air compressor models will operate more efficiently, need far less maintenance and repairs and should comply with the new governmental standards of operation. Look at your options for new air compressors, and choose a new model that is more efficient to run and known to be an eco-friendly option.

how pneumatic tattoo machines work

Artists understand that their tools influence their work. A tattoo artist with a low-quality tattoo machine will likely feel a sense of limitation. Each of your clients wants a different type of tattoo, and the possibilities are endless. Are you ready to tackle any client request that comes your way? Having an optimal tattoo machine is crucial to the success of your work. But not all tattoo machines are the same. Over the last few decades, a new product has emerged — the pneumatic tattoo machine. This machine has the potential to change how you approach your craft.

What Are Tattoo Guns?

Tattoo machines, also referred to as tattoo guns, are the centerpiece of the tattoo industry. Without them, tattoos might be far less common, and they would take far longer to produce. The industry today includes many clients who want large, intricate tattoos. These often take several multi-hour sessions to complete. The advent of tattoo guns has made the process easier and more precise.

When you give someone a tattoo, you’re injecting ink into their dermis with a tattoo gun. The dermis is the layer of skin beneath the epidermis, which is the visible top layer of skin. The tattoo gun is a powered machine that rapidly moves a needle up and down to penetrate the dermis, depositing ink. With careful attention and a steady aim, you use the tattoo gun to create a beautiful work of art on your client’s body.

Every tattoo gun possesses these three components:

  • The needle
  • The armature bar
  • The tube

The needle connects to the armature bar, which is what moves it up and down. The armature bar receives its motion from a power source, which differs among the types of tattoo guns. The needle is housed within a tube that is just long enough to let the tip of the needle stick out with each downward movement of the armature bar. This process of constant movement brings ink to the needle, and the needle delivers that ink into the client’s dermis.

The goal of every tattoo gun is to deliver ink into the client’s skin. The armature bar’s power source is where tattoo guns differentiate themselves.

Different Types of Tattoo Guns

Tattoo guns vary in their appearance and construction. There are many brands on the market, and you can choose the one that fits your style and experience level. As a tattoo artist, you know there are two basic techniques for creating tattoos, and each requires a different needle or machine. These practices are shading and lining, and their respective machines are known as shaders and liners.

Shaders, also called long-stroke tattoo machines, are used to shade an area of skin. This is necessary when adding color or giving an area of skin gradient shading. Shaders use more needles than liners and move in a slower, more methodical manner. The purpose is to completely color an area of skin, leaving no part untouched. Since shaders are slower and cover more area, they are also gentler on the skin, which is important when dealing with a large area that needs color.

Liners specialize in giving clients straight, intentional lines. This is necessary for detail-oriented work. Once you start giving a client a line, you must continue till the end or risk interrupting the line when you restart. Liners use fewer needles than shaders, but they pierce the skin at a much quicker rate. This causes liners to be more painful for clients, but it is necessary to achieve perfect lines completed in a single movement. Liners are also known as short-stroke tattoo machines.

You can use your machine as either a liner or a shader, but the machine itself can vary. There are three different types of tattoo machines available, and each carries out the same function in a different way:

1. Rotary Tattoo Gun

The rotary tattoo gun is the most popular of the tattoo machines. This is due to a few reasons, the first of which is noise. When performing an extensive tattoo session for a client, neither of you will enjoy hearing a drawn-out, annoying noise for hours. The rotary tattoo machine is relatively silent, saving you and your clients from any obnoxious sounds.

A rotary gun uses an electric motor to power its armature bar. This moves the needle up and down in rapid, cyclical motions. You can trust that the rate of your needle’s movement will be consistent, letting you carry out your work with confidence. Thanks to the fact that a rotary tattoo gun uses few components, including a lightweight motor, it weighs very little. It won’t tire out your hand, which can help you get through even the longest tattoo sessions.

Rotary tattoo guns are a good choice if your client is worried about skin damage. With their smooth, even movements, rotary guns allow you to go lighter on your client’s skin. While you can use them for either lining or shading, their gentler, faster movements make them better to use in the shading process. It’s more difficult to make straight lines with rotary tattoo guns. Some rotary guns also have options that let you switch needles with minor adjustments during sessions, giving you greater customization while creating tattoos.

If you’re going to be doing mostly shading and you want to give yourself and your clients a quieter experience, a rotary tattoo gun may be a great choice for you.

2. Coil Tattoo Gun

Coil tattoo guns get their name from the process that moves their armature bar. An alternating electromagnetic current passes through coils at the top of the machine, engaging and disengaging a magnet. This forces the armature bar up and down, tapping like a tiny hammer on the top of the needle, to continuously drive the needle into the client’s skin. This process causes coil tattoo guns to be pretty loud. It creates the signature whirring or buzzing sound many people associate with tattoo parlors.

The rate at which the needle moves in coil tattoo guns is slower than in rotary tattoo guns. You can use coil tattoo machines for both shading or lining, but their firm, intentional needle movements make them a solid choice for shading and blending in lines. They’re great at performing intricate work thanks to their slower strokes. They also use a bit more force than rotary tattoo guns, causing more damage to the client’s skin.

Coil tattoo guns may not be the best choice for a beginning tattoo artist. They contain many intricate components, making them both heavier and more complex than rotary tattoo guns. Their loud sound can also be off-putting during long sessions. While they offer customization opportunities and the ability to perform advanced, intricate work, many new tattoo artists gravitate toward rotary tattoo guns. Artists looking to challenge themselves might consider a coil tattoo gun.

3. Pneumatic Tattoo Gun

The pneumatic tattoo gun is an air-powered tattoo machine. The machine moves the needle up and down using compressed air. When it was introduced in the early 2000s, no one had seen anything like it. With its higher price, tattoo artists seemed skeptical about switching from the more familiar coil and rotary tattoo machines. Although it is a less common tattoo gun, its benefits might make it the best choice available for you.

A pneumatic tattoo gun is the most silent of the three types of tattoo machines. Using compressed air as its source of power means there is no need for humming, electric motors or noisy, buzzing coils. You can adjust the air pressure to change the speed of the needle. It’s lightweight, which makes it practical for long inking sessions. And since it uses most of the same connections and needles used for coil and rotary tattoo machines, you’ll have an easy time finding parts and accessories for it.

Tattoo artists must consider the sanitation of their equipment. Whether you use disposable tubes or washable stainless steel ones, you need to make sure you’re giving your clients a clean and fully sanitized experience. That includes cleaning your tattoo machines. Since pneumatic tattoo guns are air-powered instead of using sensitive internal components, they can be easily cleaned in an autoclave. This can cut down on the time and effort you’d normally spend cleaning your gear, letting you focus more on your latest designs and tattoo sketches.

Thanks to their lighter weight and compatibility with most accessories and needles, pneumatic tattoo guns are a great choice for both lining and shading. They allow you to keep up your stamina during long tattoo sessions and have full control over your project, even for the most intricate designs.

Evolution of Tattoo Guns

People have given and received tattoos throughout human history. In cultures around the world, tattoos have always been signs of dedication, love, creativity and even societal status. The earliest known use of tattoos dates back 5,200 years ago. These earliest instances of tattooing used primitive technology, but were tattoos nonetheless.

Tattooing has always involved the same thing — finding a way to get ink into someone’s dermis to make permanent designs. Tattoo artists accomplish this in the following three ways:

  • Piercing
  • Puncturing
  • Cutting

Different cultures have used varying methods for the tattooing process, some being signs of religious or spiritual devotion. Early tattooing tools included comb-like devices that artists dipped into ink and pierced into the skin. Some people would pierce the skin in a design until they drew blood. They would then smear ink into these wounds so that when they healed, it would trap the ink under the skin in the desired design.

As generations passed, artists developed other methods, such as using long needles made of bone or glass to repeatedly pierce the skin with ink. Artists would sometimes place these needles in long tubes to give themselves more control over the designs.

In 1876, Thomas Edison invented the inspiration for modern tattoo machines. He created an electric motorized pen that would pierce holes into materials to create stencils that could be used to mass-produce text. While the invention didn’t maintain much popularity in the publishing world, tattoo artists saw its potential. Before the turn of the century, the rotary tattoo machine had been patented. In the early 1900s, the coil tattoo gun followed suit. They were the only two tattoo machine options throughout the 1900s.

With the new millennium came a new tattoo machine: pneumatic tattoo guns. They broke new ground, as no one had ever seen someone use an air compressor tattoo machine before. Now, with all their benefits, pneumatic tattoo machines could change how tattoo artists approach their craft for years to come.

Benefits of Compressed Air for Pneumatic Tattoo Machines

Never before has such a versatile, lightweight and user-friendly option as the pneumatic tattoo gun been available for tattoo artists. Using an air compressor for your tattoo machine may feel foreign at first, but before long you may never want to go back to your old rotary or coil machine. Using compressed air as the power source for your tattoo machine has some undeniable benefits, including the following:

  • Lightweight: The lack of motors or coils means that your pneumatic tattoo machine is easy to hold and operate. This can help you succeed in even the longest tattoo sessions.
  • Easy to clean: Cleanup is easier since you can sterilize a pneumatic tattoo machine in an autoclave. Washing the components by hand can be a thing of the past.
  • Low noise: Enjoy more peace and quiet as you work with no buzzing sounds from motors or coils.
  • Quick setup and teardown: Pneumatic tattoo machines are compatible with standard tattoo accessories. Since all you have to do is hook up to an air compressor, getting started and tearing down after a long day’s work is simple and convenient.
  • Take your craft on the go: With a pneumatic tattoo machine, as long as you have a place to power your compressor, you can give clients tattoos anywhere. From festivals to outdoor art venues, you’re only limited by where you want to create.

how to winterize an rv with compressed air

The summer travel season is winding down, and it won’t be long before colder temperatures arrive. For RV owners who spend the winter in colder climates, the cold season’s pending arrival means it’s time to winterize your RV.

When winterizing an RV, it’s a good idea to methodically inspect the interior and exterior, making sure each system is in good working order. In addition to the engine, batteries, propane tanks and interior, one of the most important areas to winterize in an RV is the pipes that carry water.

Draining the water from the pipes before it gets cold prevents the water from freezing and expanding until the pipes burst. Avoiding this and other problems before they happen is the best way to ensure you’ll be back on the road — and not in the shop — as soon as warmer temperatures return.

Why Do You Need to Winterize Your RV?

Winterizing is essential to extending an RV’s lifespan. Removing and storing external propane tanks, cleaning old food out of the refrigerator and storing batteries in a dry location — all these things keep your RV working properly to preserve your comfort during the travel season.

If you spend winters in an area prone to harsh weather, the cold temperatures can wreak havoc on an RV’s systems, especially its plumbing. If any amount of water is left inside the pipes, it can freeze and expand, causing the pipes to burst — just as they would in a home where the temperature drops too low. Burst pipes can make a big mess and cost a lot to repair.

One common method of draining pipes for winter is to remove some of the water and then pour antifreeze into the plumbing. The antifreeze lowers the water’s freezing temperature, making it less likely that the moisture left behind will turn to ice. The problem with using antifreeze is that there really isn’t a good way to drain it all out of the pipes. Your family may end up drinking or showering in water with trace amounts of antifreeze in it, or a beloved pet may consume it.

A safer, more effective alternative to antifreeze is using compressed air to winterize the pipes in your RV.

How to Use Compressed Air to Winterize

Winterizing an RV with compressed air means you essentially blow air through the pipes to remove any water left behind from when you drained the plumbing. Although you can hire a professional company to do this for you, learning how to winterize your plumbing is a relatively simple DIY process:

1. Empty the Sewage System

Before you do anything else, take the RV to a dump station and hook up the black and gray tanks to the intake. Drain the black tank — containing human waste — first. The water from the gray tank will be used to flush the black tank. Once both are empty, use a hose to rinse them off at the dump station.

2. Clean Out the Interior

Once the tanks are cleared out, take some time to clean up the RV’s interior. Wash and put away dishes and throw away or remove all food items. Check to make sure there are no open windows or doors. Otherwise, you’ll open the RV up in the spring and find a bird or mouse has made a home there.

3. Lower the Hitch

Lower the hitch slightly so the water coming out of the pipes can flow out of the release valve. Don’t lower the RV too much — just enough that it’s slightly leaning toward the side where the main water drain is located. This is the petcock.

4. Drain the Water

Remove the petcock and allow the water from inside the RV to begin draining out. To help the water drain, go inside the RV and turn on the faucets and shower to encourage water to flow out of the pipes. It’s also a good idea to flush the toilet a couple times.

5. Hook up the Air Compressor

Connect the RV’s blowout plug to the compressor’s air hose. Then connect the plug to the RV’s water inlet. Set the air compressor’s maximum pressure between 30 and 50 pounds per square inch (psi) and begin pumping air into the pipes at 30-second intervals. After 30 seconds, pause for several seconds, and then start again. Repeat this process until there is no more water coming out of the drain.

What Type of Air Compressor Should You Use to Winterize?

When choosing the right air compressor to winterize your RV, the tank’s volume is more important than the amount of pressure. For example, you can use a 2-gallon compressor that allows you to set it between 30 and 50 psi. The tank’s size is less important than its ability to stay within this ideal pressure range. Make sure whatever tank you’re using can handle the right amount of pressure necessary to get the job done.

Benefits of Using Compressed Air to Winterize

When winterizing with compressed air, this method offers two primary benefits:

1. Ease of Use

Compressed air is easy to use to blow water out of your RV’s pipes. All you have to do is connect the compressor and get started. A small air compressor can travel with you or be stored in a garage at home, so you can pull it out each fall when you’re ready to winterize. If you don’t own one, they’re easy to rent or borrow from a friend.

2. Safe for People and Pets

Regular antifreeze is toxic, meaning that even if you flush the lines in the spring before you start using the water, your family and guests may be exposed to trace amounts of antifreeze in their drinking water and shower water. RV antifreeze is nontoxic, which means RV owners may assume they can just dump it on the ground when they empty their pipes. But even nontoxic antifreeze shouldn’t be dumped where it can leech into the groundwater. Antifreeze is also toxic to animals, such as family pets.

Choose Quincy Compressor for Your Air Compressor Needs

At Quincy Compressor, we know firsthand the value of family. Spending time together traveling the open road creates family memories that last a lifetime. The last thing you need is to have those precious memories interrupted by busted pipes that weren’t properly winterized.

guide to air compressors for scuba diving

Compressed air plays an important role in many fields and industries, but when it comes to scuba diving, high-quality, breathable compressed air is critical. For this reason, all divers should understand how a diving air compressor works, plus how to maintain it and perform basic repairs.

If you’re new to diving or are interested in taking up the sport, we will provide you with a useful overview of scuba dive compressors and some handy maintenance tips.

Differences Between Regular Air Compressors vs. Scuba Air Compressors

You cannot use a regular air compressor for scuba diving, as it differs significantly from models designed for underwater use. A scuba compressor is a high-pressure air compressor system designed to fill the tank that a diver uses to breathe underwater. This type of compressor also supplies air for firefighters and the oxygen tanks you find in hospitals.

Scuba compressors differ from regular air compressors in two primary ways:

1. Pressure

A scuba tank generally must be filled at very high pressures, roughly 3,000 pounds per square inch (psi). Regular air compressors can only provide a small fraction of this pressure.

2. Quality

Compressed air for scuba diving must be clean. Air compressors for scuba diving, unlike most other types of compressors, are designed to provide breathable, clean air, as contaminated air could lead to serious health problems or even death. It is safe to breathe air from a scuba compressor as long as it is filtered appropriately.

To ensure the air supply is clean, scuba compressors are equipped with a series of filters and moisture separators that remove moisture and various other contaminants. Once the moisture is removed, the compressed air then goes through a series of activated carbon filters that remove numerous hydrocarbons and render carbon monoxide (CO) harmless.

How Do Scuba Air Compressors Work?

The process by which a scuba compressor compresses air is complex, and a full explanation is beyond this article’s scope, but we will provide an overview of the four basic stages:

1. Compression and Cooling

In the first stage, the scuba compressor will take air in via its intake filter, after which it will compress the air to approximately 100 to 140 psi when pushing the air out. This process produces significant heat. This is why scuba compressors are equipped with a coil or intercooler, which helps dissipate this heat before the air continues to the next stage.

2. More Compression, More Cooling and Moisture Separation

The air, which has just been slightly compressed and cooled, now enters the next stage, whereby it gets compressed again. This time, it’s compressed to a pressure between 800 and 1,000 psi. Once this occurs, the air is then cooled again and passes through a moisture separator. After this, it is ready for the next stage.

3. Additional Compression, Cooling and Moisture Separation

In this third stage, the air is compressed even more, sometimes up to as high as 5,000 psi. After this process, the air passes through yet another cooler and moisture separator. The air may then travel through several other filters before continuing to the last stage.

4. Processing Through the Back Pressure Valve

The final step of the process involves the back pressure valve, a component that forces your compressor to run balanced. It is generally set to pressures ranging from 2,700 to 3,300 psi. This element also influences how filtration operates.

Types of Scuba Air Compressors

Portable breathing air compressors come in three categories, classified by their power sources:

1. Electric Compressors

Compressors with an electric motor are the most popular type of scuba air compressor and offer the following advantages:

  • Quiet operation: Electric compressors run much more quietly than either gas or diesel models, so if you’re concerned about noise, you’ll be best off choosing electric.
  • Low maintenance: Electric compressors require less upkeep than their gas and diesel counterparts.

There are, however, a few potential drawbacks for electric compressors, including:

  • Limited portability: As electric compressors must be connected to a power source to operate, they’re not as portable as gas or diesel versions.
  • Potential size limitations: If you only have 220- or 240-volt single-phase electricity, you will only be able to use smaller models. If you want a larger model, you’ll need to have three-phase electricity, which is usually only found in commercial buildings.

2. Gas Compressors

A gas compressor features a motor that helps the compressor run. Some pros of gas compressors include:

  • Portability: Gas compressors are a great option if you need power off the grid.
  • Availability: If you want a portable compressor, you’ll likely find a gas model more easily than a diesel one. If your gas motor needs to be repaired, it will also be easier to find repair technicians and replacement parts. However, in some parts of the world, diesel is the primary fuel, meaning a diesel engine may be the better choice.
  • Affordability: Regarding both upfront and operational expenses, a gas engine generally costs less than a diesel model.

However, there are a few factors that may make gas compressors less desirable for some users:

  • Noise: Gas compressors make more noise than electric ones, although they are quieter than diesel compressors.
  • Maintenance: To keep a gas compressor in top shape, you’ll need to perform a fair degree of regular maintenance tasks and buy several fuel additives.
  • Carbon monoxide emissions: Gas motors emit carbon monoxide, which must be kept away from the compressor’s intake. This is so the CO will not degrade the filter or make its way into the breathing air. To do this, you must use the air intake tube provided by the manufacturer and place the engine’s exhaust downwind from the tube.

3. Diesel Compressors

The third type is the diesel engine compressor, which is similar in many ways to the gas engine but also notably different in some respects.

Here are a few advantages you can get from using diesel engine compressors:

  • High-quality, durable components: Diesel engines generally consist of high-quality parts that last longer than ones in gas engines.
  • Easy portability: Like gas compressors, diesel engines don’t require an electric connection, meaning you can take them to more places.
  • Potentially greater availability: If you live in a region of the world where diesel is more common than gas, you’ll likely want to select this type of air compressor.

Below are a few considerations that may make some buyers think twice about diesel:

  • Noise: Diesel engines are loud — even more so than gas models.
  • Weight: Diesel compressors are bulky and heavy, which can negatively affect their portability.
  • Price: Diesel engines cost more than gas versions concerning both upfront cost and maintenance.

Different Pressure Levels in Scuba Air Compressors

In addition to their power sources, scuba air compressors can also be categorized concerning how much air pressure they provide:

1. Low-Pressure Compressors

Low-pressure compressors weigh relatively little and are used for surface supplied diving. These compressors are put in flotation rings that float on the water’s surface, and they supply underwater divers with air via a hose. 

2. High-Pressure Compressors

Compressors categorized as high-pressure provide air pressures between 3,200 and 5,000 psi. They’re commonly found in commercial diving, and dive shops use them as well. They tend to be bulkier and heavier than their low-pressure counterparts, but they are undoubtedly better for filling tanks.

Before buying a compressor, consider its maximum pressure. The compressor’s capacity should be proportional to your tank’s size. Smaller tanks, for instance, may struggle with high-pressure compressors, whereas low-pressure models might not compress the air sufficiently in a large tank.

Oil-Free vs. Oil-Lubricated Scuba Dive Compressors

A third distinction concerning the different compressor classifications is between oil-free and oil-lubricated air compressors:

1. Oil-Free Air Compressors

Oil-free air compressors use ceramic rings and cylinder liners, which do not require any lubrication. The major advantage of this compressor type is that, as there’s no oil, there’s no risk of this fluid contaminating the breathing air. However, oil-free compressors cost significantly more than oil-lubricated ones.

2. Oil-Lubricated Air Compressors

Oil-lubricated compressors are more common and cost much less than oil-free models. These machines use oil to lubricate their moving components and cylinders. Of course, this means that, if the oil comes in contact with the breathing air, there will always be at least a tiny amount of oil coming out of the compressor with the air. This is referred to as oil-carry-over. Although the amount is small, this oil needs to be removed, which is accomplished with specialized filters.

How to Fill a Scuba Tank With an Air Compressor

To ensure your underwater excursion is as safe as possible, make sure your gear is safe for use before you get in the water. When ensuring your safety, the first thing you should do is refill your tank. To do this, follow these steps below:

  1. Check your tank’s compliance. A scuba tank, just like any other pressurized tank, has to be inspected regularly. If your tank hasn’t been tested recently or is just too old, refrain from using it. It could be faulty, which could have disastrous consequences during filling up the tank or diving underwater.
  2. Release any excess air. If there’s any air remaining in your tank, let it out. You shouldn’t add any more air until this amount has been released.
  3. Inspect the tank for loose objects and damage. If your tank isn’t completely sealed, it becomes ineffective. Give your tank a spin and see if there are any holes or cracks. Shake your tank to see if you hear any debris or water inside. If there’s any sloshing water or rattling, you should discard your tank right away. This step is vital because if there’s a leak, and you don’t discover it until you’ve started your dive, it could be too late.
  4. Place your tank in cold water. This action prevents your tank and the air inside from expanding due to heat. This step will help minimize the risk of your tank exploding in front of you. Moreover, by submerging it in water, you’ll more easily spot cracks and holes, as air bubbles coming from the tank’s sides will indicate a compromised surface.
  5. Set your compressor up. Before you can use your compressor to fill up your tank, you need to configure it for your tank. This means checking all the required meters and gauges and ensuring everything is correct. Also, check that your automatic shutoff is in working order.
  6. Attach your yoke. This step is simple but crucial — attach the compressor’s yoke to your tank’s valve. Closely inspect each component’s connecting points and make sure they’re free of debris and dirt.
  7. Fill your tank. Turn on your compressor and let it fill your tank up. Keep a close eye on the gauges, ensuring your automatic shutoff continues working properly. If it malfunctions, you’ll need to turn your compressor off yourself.

How to Maintain Your Scuba Compressor

Properly maintaining and fixing your air compressor is important, and failing to do so can lead to an explosion.

For air compressors to work properly, three main functions are required. They are:

  • Applying adequate power.
  • Maintaining pressure.
  • Controlling the flow of the compressed air.

If your compressor stops working, it is likely due to the failure of one of these three functions above. In this section, we’ll share some useful DIY fixes you can perform yourself. Be aware that if you have a high-pressure compressor and your tank has been damaged, the compressor could rupture. Do not attempt any complex repairs — leave those to the professionals instead.

Here are some things you can do on your own to ensure your compressor’s safe operation:

1. Adjusting Air Flow

To adjust the air flow, follow these steps:

  1. Remove the cover. Remove the plastic cover from the compressor’s top by taking out the screws. Then, lift off the cover, which will give you access to the screws on your pressure maintaining valve.
  2. Remove screws underneath the cover. There will be two screws, one of which is for turning off the compressor. The other turns it on.
  3. Check your compressor setting. Turn on your compressor, turn it off and then check its setting. You can adjust the pressure using the upper screw.
  4. Adjust the pressure. To raise the compressor’s pressure, tighten the screw. If you want to reduce the pressure, loosen it. Then, engage your pressure release valve, noting what the pressure is once the compressor comes on.
  5. Adjust the setting. Using the lower screw, adjust the setting. When you arrive at the right pressure, replace the cover and screws removed in steps one and two.

2. Restoring Power

If your compressor has lost power, follow these steps to restore it:

  1. Begin with the obvious. Before doing anything else, make sure your compressor is plugged in fully and your switch is flipped on.
  2. Reset the compressor. If this doesn’t work, press your reset button. This should be a round black or red button typically found on the side where the motor is, usually by your power cord.
  3. Examine the cord. Make sure your power cord isn’t damaged.
  4. Plug it in somewhere else. Try plugging your compressor into a different socket. Make sure the plug’s circuit breaker is tripped. Then, turn off the breaker and turn it back on again.
  5. Plug another device into the outlet. If you’re still not successful, see if the outlet works by plugging another device in. If it works for the other device, this most likely means the problem is not something you can fix yourself. Have a professional examine your compressor.

3. Repairing a Leak

If your compressor is leaking, take the following steps:

  1. Unplug its components. Start by unplugging all the hoses and tools. Then, turn on your compressor so it can start charging.
  2. Spray soapy water on the compressor. Make a soapy water solution and pour or spray it all around the compressor’s fittings. Look closely to see if any bubbles form. If bubbles form, this means there’s a leak.
  3. Turn off the compressor. Shut your machine off, and let the pressure out from your tank as well.
  4. Apply tape on fittings. Remove the fittings where bubbles formed and apply tape — preferably Teflon tape — on the fittings’ threads. Then, put them back on, tightening them down.
  5. Turn compressor back on. Turn on your compressor and let it charge again.
  6. Spray soapy water once again. Perform the same test as in step two. If there are still bubbles, turn the compressor off and repeat steps three through five.

Additional Maintenance Tasks for Your Diving Air Compressor

In addition to simple repairs, we’d also like to share five routine tasks you can perform to keep your compressor in top shape. Doing these things regularly will extend your compressor’s lifespan and help you avoid costly fixes:

1. Remove Moisture From Your Tank

One important task you should perform regularly is removing moisture from the tank. This tank tends to create moisture when operating.

Compressors usually come equipped with a valve specifically designed to remove this moisture. It is essential to use it after every use, as failing to do so can lead to problems. Before using the valve, however, don’t forget to release the pressure in your tanks first.

2. Clean the Intake Vents

If the intake vents on your compressor are dusty, it will cause your machine to overwork. In turn, forcing your compressor to overwork will usually lead to a complete system failure. The time you take to clean these vents pays off later in the form of increased efficiency.

3. Inspect and Tighten Your Fasteners

You may have noticed that, when air compressors run, they vibrate a lot. Over a long period, vibrations cause your fasteners to loosen, which is why these components should be regularly checked and tightened. Neglecting this task can cause serious damage to your compressor.

4. Examine and Replace Your Hoses When Necessary

The hoses serve as some of your compressor’s most vital parts. But keep in mind that the greater the length of these hoses, the more likely they are to malfunction. Inspect them routinely to catch issues before they do serious damage.

It is crucial to invest in high-quality compressor hoses. If you skimp on quality to save money, this will usually backfire on you.

5. Frequently Inspect and Change Your Air Filters

Yet another task you should regularly perform is to inspect and change the compressor’s air filters. If debris makes its way past these filters, the compressor may shut down.

Routinely evaluating your filters is also a good way to find out how they’re holding up. Air filters covered with debris should be replaced immediately.

air cooled vs water cooled compressor

An air compressor is a positive displacement compressor that produces energy to power commercial tools and equipment. Rotary screw air compressors generate heat as they function, which is why compressed air needs to be cooled — either with air or a chilled liquid.

Whether you get a water-cooled or air-cooled compressor for your business depends on your commercial space’s location, tools and size. Explore some of the comparisons between an air-cooled vs. water-cooled compressor to help you make a decision.

How Does an Air-Cooled Compressor Work?

An air-cooled compressor uses air to reduce the temperature of the compressed air and any other material present. When the compressor makes heat, the air-cooled circuit reduces the hot air with a fan and radiator. An air-cooled compressor is the most common air compressor cooling system, making it more accessible than water-cooled systems.

Industries can recover the heat loss for an air-cooled compressor by using the energy to heat buildings or power a preheating battery, thus saving companies money on utility expenses. The circuit directs the heat to an area with a fan, but if the building doesn’t need more heat, the unit releases the hot air into the atmosphere through the thermostat or air damper control.

How Does a Water-Cooled Compressor Work?

Water-cooled compressors use liquid coolant from an external unit to cool the compressed air and any other substances present during the compression process. The cooling circuit reduces the heat with a shell and tube exchanger. Water-cooled units are more common in machines with higher horsepower.

Companies can reuse the water from the compressor in a hot water heating system, usually for showering, washing or cleaning. A water-cooled screw compressor may allow a business to invest in a smaller water boiler because you won’t need as much hot water.

Energy Costs of Air-Cooled vs. Water-Cooled

When considering each air compressor cooling system’s energy cost, you should keep the following factors in mind:

  • Energy expenditure: Air-cooled units require more power than water-cooled ones.
  • Electricity cost: Water-cooled compressors cost a lot of money regarding electricity, water and water treatment expenses, so you’ll save money with air-cooled equipment.
  • Ability to recoup resources: Both types of compressor cooling systems offer reusable resources to recompense energy expenditure costs. If you can reuse a liquid-cooled compressor’s water to preheat boilers, you can save on gas and heating bills. You can also use the heated air from an air-cooled compressor to make a room warmer and power a fluid heat exchanger.

Requirements for Air-Cooled Compressors

An air-cooled screw compressor needs enough cooling air and space to provide adequate airflow. Improper planning may result in problems with regulating your commercial facility’s temperature. If the compressor room is too hot, the business could experience equipment failure and unplanned shutdowns.

To protect your equipment and continue workflow, install ductwork from both sides of the compressor to allow air to travel throughout your space. You can also use the heat from the vents to warm up your commercial space in the winter. If your business doesn’t have enough room for additional equipment, it might be better to set up a water-cooled compressor.

Requirements for Water-Cooled Compressors

A water-cooled screw compressor needs high-quality cooling water to function. If you get water from a lake, ocean, well or river, you’d need a cooling tower and closed-loop system to filter the water and increase your system’s lifespan.

Unless your building already has this equipment, you’ll need to include the cost of purchasing, installing and maintaining this new machinery along with your water-cooled compressor. If you already have a closed-loop cooling system on-site, make sure it can accommodate your water-cooled compressor before you install it.

Which System Should You Choose?

Air compressors can serve various industrial applications, but you need to choose the best type for your specific business. Here are some factors to consider when looking for the right rotary screw air compressor:

  • Cost of operation and resources: With the rising cost of water regulation, it’s essential to consider how much you’ll have to pay to use and maintain your equipment. Since water-cooled air systems utilize much more water to reduce the air’s heat, they can be expensive. Air-cooled screw compressors don’t use as much water to power their products, and they also have a lower upfront and installation cost.
  • Requirements for air demand: When considering your air demand requirements, account for the product’s horsepower (hp), cubic feet per minute (cfm) rating and pounds per square inch (psi) rating. A unit’s horsepower offers more potential for meeting high air demands. The cfm rating measures how much air the compressor can produce each minute to give you the appropriate psi. Look at the cfm and psi ratings to determine which one can accommodate your tools and energy requirements.
  • Type of tools your industry uses: Consider your equipment’s horsepower requirements and figure out the appropriate cfm and psi ratings for your rotary screw air compressor. You could invest in a smaller unit if you use your tools sporadically, but you should get a larger one if you run them continually.
  • The compressor room’s layout: Before choosing an air compressor, make sure the room has enough space for it. If space is an issue, you could get a few smaller compressors instead of buying one large unit and put them in multiple areas around the factory. Keep in mind that most rotary screw compressors with less horsepower usually aren’t available in water-cooled models.
  • The compressor room’s ventilation: Air-cooled compressors need adequate airflow to function and regulate their temperature. If the room doesn’t have the proper ventilation, the area could get too hot and the equipment could shut down, delaying projects. You also would need to keep your air-cooled compressor away from a hot boiler room or fumes. Water-cooled compressors can better accommodate small spaces and higher temperatures.

When considering these factors, remember that one type of rotary screw air compressor isn’t better than the other. Your choice between air-cooled vs. water-cooled compressors depends on your specific application and location. Discuss your options with a compressed air expert before deciding which one would be appropriate for your industry.

High quality rotary screw compressors such as those offered for sale by Quincy Compressor are designed, engineered and built to provide many years of reliable service. However, a screw-type air compressor is a complex machine consisting of many moving (and non-moving) parts and components. Regular preventive maintenance is essential for ensuring efficient operation, a long air compressor lifespan and reduced downtime due to the need for unscheduled repairs.

Whether you own a high pressure, low pressure or combined screw air compressor, your best source regarding proper machine maintenance is the product manual. Your manufacturer may recommend the performance of routine maintenance at regularly scheduled time intervals or by monitoring the number of running hours. In general, maintenance of rotary screw air compressors entails the following areas:

  • Airends: The airend, or the screw element, is the heart of any rotary screw compressor: This is where the actual compression takes place. Airends can be damaged by excessive heat, contamination in the air and even dirty rotary screw compressor fluid. Your preventive maintenance procedure should include regular airend inspections — excessive noise and vibration can also be a telltale sign of an airend issue.
  • Drive train: Check the rotary compressor’s drive train to ensure it is properly aligned and that the gear drives are properly lubricated. The tension of V-belt drives should be adjusted approximately every 500 hours. Immediately replace frayed or worn belts.
  • Motor: Keep the motor bearings properly lubricated and replace them before they wear out. Also monitor the ampere draw to minimize the likelihood of overloading. Maintaining sufficient ventilation in the compressor room or operating environment can go a long way toward maximizing the motor’s lifespan.
  • Filters: One of the easiest and most cost-effective ways to prevent premature wear is to replace your rotary compressor’s filters on a regular basis, as this will reduce airend wear and component contamination. Replacement of air inlet filters is recommended every two thousand hours, and you should change the fluid filters every one thousand hours.
  • Lubricants: Lubricants perform the vital functions of removing contaminants, protecting moving parts from excess wear and keeping the compressor cool. The best advice regarding when to change rotary screw compressor fluid is to adhere to the manufacturer’s recommended schedule. Regular oil sampling can help to lengthen the lubricant’s lifespan, and can affect warranty compliance in some cases.

Other general rotary screw air compressor maintenance tips include keeping the machine as clean as possible. In addition to damaging compressor components, dirt and debris can actually cause the temperature of the compressed air to increase. Also avoid operating the compressor at high temperatures for extended periods of time.

Rotary Screw Air Compressor Horsepower

rotary screw air compressor horsepower

When you’re shopping for air compressors, you’ll typically find that they’re rated by horsepower: You’ll see the horsepower rating prominently featured in the product name and description, such as the “Quincy 7.5 hp rotary screw air compressor,” the “Quincy 30 hp air compressor” or the “Quincy 60 hp air compressor.”

One of the most important decisions you’ll have to make when choosing a rotary screw compressor is the amount of horsepower you need the compressor to provide. Horsepower is essentially a measurement of the amount of mechanical energy the compressor uses to complete the compression function.

Air compressor horsepower is further defined in terms of peak horsepower (also known as brake horsepower) and running or rated horsepower. Peak horsepower is the maximum hp output the motor is capable of producing while the start windings are engaged, and can be as much as seven times the rated horsepower.

However, using peak hp to evaluate a compressor’s power capacity can be misleading, as the motor only reaches its peak hp level when the compressor is starting up. Rated horsepower can provide a more realistic measurement of the compressor’s true capacity, as it provides the hp level after the running motor has reached its designated RPM and the start windings are no longer engaged.

Other Horsepower Factors to Consider

When evaluating rotary screw compressors, you should also consider its duty cycle. This indicates whether the compressor can run at full load horsepower on a continuous or only an intermittent basis. Additionally, you should determine the compressor’s service factor, which is the percentage of rated horsepower at which the compressor motor can be operated safely. Generally, the higher the service factor, the greater the motor’s capacity to handle higher temperatures or other demanding operating conditions without overheating or failing.

Is Horsepower Really That Important?

Many people buy compressors using the horsepower rating as a primary factor. However, it’s important to know that horsepower only refers to the motor’s ability to power the compressor pump. The higher the horsepower rating, the more efficiently the pump can fill the air tank and the lower the compressor’s recovery time.

Horsepower has no impact on the airflow from the tank to the tool or equipment you’re using: A higher horsepower doesn’t enable your tool to work faster.

While you certainly need enough horsepower for your compressed air applications, you also need to consider cubic feet per minute (cfm), which provides a true indication of how much air the compressor can actually deliver. The larger the pneumatic tool, the higher the cfm generally required to operate it. To determine the appropriate compressor cfm, add up the total cfm requirements for all the tools you operate simultaneously and then choose a compressor with a cfm that exceeds this amount by 20-25 percent.

Multi-Stage Compressors

NFPA

Reciprocating/piston compressors use a cylinder to force air into a chamber, where it is compressed. The simplest compressor designs feature a singlecylinder/chamber arrangement. While straightforward, this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air.

That’s where multi-stage compressors come in. By increasing the number of cylinder stages, these machines work more effectively and can handle more tools at once.

How Multi-Stage Compressors Work

Multi-stage compressors feature two or more piston cylinders, each of a different diameter. After the first compression stage, air passes through a heat exchanger, where it is cooled before arriving at the second cylinder. Cooling the air reduces the work needed to compress it during the second or third stages.

In a two-stage compressor, the air passes through two chambers total. In the second chamber, it is pressurized to the required extent. In a three-stage compressor, an additional cycle of compression and cooling occurs before this.


Benefits of Multi-Stage Compression

Both single and multi-stage compressors have their benefits. The right one for your application will depend on a number of factors. Specific advantages of a three- or two-stage compressor design include:

  • Improved efficiency: Two-stage compressors perform less work to compress air to a given pressure, which means your operating costs are lower.
  • Better reliability: The intercooling stage of two-stage compression creates less chance of overheating, which in turn means more uptime and better productivity.
  • Less moisture buildup: Cooler air has a lower moisture content. Moisture in compressed air can lead to equipment failure and premature wear. Using a two- or three-stage compressor can potentially save you from having to purchase a separate air dryer.
  • Smaller footprint: For heavy-duty applications, multi-stage compressors deliver greater air pressure (PSI) at higher capacities (CFM) than single-stage machines of comparable size.
  • Few maintenance requirements: Thanks to smaller components and cooler temperatures, wearable components don’t wear out as quickly. As a result, recommended service intervals are longer.

Applications

Clearly, there are benefits to selecting a multi-stage machine. However, their higher cost means they are not necessarily the right choice for every application. Typically, single-stage compressors are best for lower pressure, light-duty, periodic use applications. Two- or three-stage air compressors, on the other hand, offer more efficiency and reliability for continuous use applications, such as manufacturing and auto repair.

Many reciprocating compressors come in both single- and two-stage options. If you’ve already selected a particular machine, you may be wondering whether you need a single- or multi-stage version. Here are six things to consider when choosing an air compressor to decide if a multi-stage system is right for your application:

  1. Pressure required: Before considering anything else, you can know for sure you need a two- or three-stage compressor if you need to produce high pressure. Because air is compressed in two or more steps, multi-stage compressors can deliver higher pressuresTypically, any pressure above 100 PSIG will demand a multi-stage compressor for the most efficiency.
  2. Volume of air required: An industrial multi-stage air compressor can pressurize more cubic feet of air per minute (CFM) than a single-stage compressor. Since most compressors take some downtime between pressure cycles, a higher volume produced per cycle can increase productivity. Machinery and air tools used for significant lengths of time will both require more air.
  3. Need for temperature control: Multi-stage compressors can regulate air temperature. Because they cool air as it passes between each chamber, the output air has a lower temperature. When heat can damage or reduce the efficiency of your air-powered equipment, choose a multi-stage compressor.
  4. Need for oil-free applications: Intercooling, which is used in most multi-stage compressors, it increases the moisture in the airThis moisture can mix with the oil in an oil-flooded compressor and cause issues with the machinery. So, most oil-free compressor systems are dual-stage.
  5. Space you have: The smallest single-stage air compressor will take up less room than the smallest dual-stage air compressor. For a DIY or contracting project, a single-stage air compressor may be lighter and more portable. When it comes to larger air compressors, a two-stage compressor will have a higher output than a single-stage compressor of the same size. So, for industrial applications, a multi-stage compressor will save space.
  6. Initial cost versus lifetime cost: The price of air compressing equipment is only 12% of the total cost of producing compressed air. So, while a single-stage compressor can be more affordable to buy, it’s critical to consider the lifetime cost, too. Most of the cost of compressed air comes from the electricity consumed. In this case, two- and three-stage compressors have the advantage because cool air compresses with less mechanical work. For small applications, the lower initial cost may outweigh the benefits of an efficient design. For larger applications, the lifetime cost of the machine is paramount.

Buying a New vs. Used Air Compressor: Which One Is Best?

When you need an air compressor for your operations, you have a choice to make — will you buy new or used? This comes after deciding the specific type of compressor you need, from rotary screw to reciprocating, so making another decision may be overwhelming. There are plenty of pros and cons for either type of air compressor, and you have many things to factor into your choice.

When buying a new versus used air compressor, which one is best? We’ll outline the differences as well as the advantages and disadvantages below to help you make your choice.

Difference Between New vs. Used Air Compressors

Before you even learn the difference between used and new air compressors, you may wonder if you can purchase used air compressors. The answer is yes. Plenty of industries use air compressors for various work tasks. As a result, there’s quite the market for both new and used air compressors. The difference is simple — companies or individuals have previously employed used air compressors in their work, while new ones have never been used before.

Used air compressors may come from companies that have decided to upgrade their system. They might also come from businesses that have downsized their equipment needs. Ideally, you’ll find a used air compressor that someone didn’t use often but maintained well.

Depending on who you purchase used equipment from, you may receive information from the past owner. You could discover how well they maintained the system, how long they had it for and what issues they had, if any. Sellers could also assess the equipment and either make repairs or advise you on any maintenance or replacements the air compressor needs. All that will depend on who you shop with and if the information is available from the previous owner.

When you buy a new air compressor, you’ll have access to all the specs you’d expect to receive with a new purchase. You get a current product that manufacturers back with decades of research and development. No one owned it before, so there’s no history of problems or repairs to look into.

No matter which option you shop for, you’ll likely find the type of air compressor you need for your operations. It just depends on current availability and demand. The main differences come with the pros and cons of new versus used air compressors.

New Air Compressors

With the right budget and a need for a quality machine, a new air compressor can guarantee you get the equipment you want. Compare the pros and cons of purchasing a new air compressor to see if it’d be the right choice for your operations.

Benefits of Buying New Air Compressors

Purchasing a new air compressor comes with various advantages, especially when you compare it to getting a secondhand one. As long as your operations use the new equipment often, you’ll get these benefits of buying new air compressors:

  • Latest technology: New air compressors use the latest technology to make your operations smoother. You can cut down on lead times and have more flexibility or consistency when you use an air compressor with the newest technology.
  • Higher efficiency: A new air compressor may use power more efficiently than a used option. New machinery won’t have initial damage or required maintenance, which used equipment could have. Leaks, clogged air filters, incorrect pressure readings and other issues all impact an air compressor’s efficiency. You most likely won’t have a problem with those components in a new system.
  • Longer life span: A used piece of equipment can have years taken off its life span, depending on how long the previous owner used it. A new machine has never been used, so you get a longer life span. You can further extend your air compressor’s life span by following maintenance tips and getting an air compressor audit, which helps protect your investment.
  • Higher return on investment (ROI): As you decide which system will work for you, you’ll wonder which has the best ROI between used or new air compressors. You’ll get the most value from a new unit, thanks to its longer life span and quality components. A new air compressor is cost-effective because it will have better energy efficiency, and you likely won’t need to replace or repair components right away. A new air compressor also adds to your business’ equity, which is beneficial if you ever want to expand or borrow funds. To ensure you maintain that ROI, conduct regular maintenance and audits.
  • Possibility for warranties: Depending on which equipment you purchase and where you buy it from, you could get a warranty. A warranty helps ensure you have little to no costs if your air compressor needs repairs or replacements. If there are any defects with your brand new equipment, a warranty may cover replacements then, as well. Look into the specific terms of your warranty to understand your coverage better, and check for what it covers and how long it lasts.

Disadvantages of Buying New Air Compressors

The primary disadvantage of buying a new air compressor is its cost. You’ll probably pay significantly more for a new system compared to a used one. But that’s because you’re paying for all the benefits of buying new air compressors. You get the latest technology, excellent warranty coverage and better efficiency. The machine also doesn’t have a history, unlike used options. If you can afford the cost of buying a new air compressor, it may be worth it in favor of all the advantages you get.

Used Air Compressors

If you purchase a used air compressor, you have to rely on the previous owner to have maintained it. With proper prior maintenance and a trustworthy seller, you could get a quality secondhand air compressor that suits your needs. Still, the machine will have its pros and cons. Evaluate the benefits and drawbacks of purchasing a used air compressor to see if it’d be right for you.

Benefits of Buying Used Air Compressors

To see if a used air compressor would be right for you, first consider the advantages. Compared to a brand new machine, you’ll get these benefits of buying used air compressors:

  • Lower cost: The most appealing benefit of used equipment is a lower price. In some cases, you can purchase multiple used air compressors for the same price you could get for one piece of new equipment. Don’t let a lower price tag be the only deciding factor, though. New equipment comes with benefits that used machinery doesn’t, which validates a higher price tag.
  • No initial depreciation: When you buy any sort of new machinery or equipment, its value immediately depreciates. You won’t have that problem with used equipment. It comes at an initial lower cost, and since someone has used it before, it has already gone through its initial depreciation.
  • Quality refurbishments: Depending on the manufacturer and seller, you might get a high-quality refurbished machine. Components may be new yet compatible with the used air compressor, which would give you a more efficient and long-lasting system. Not every secondhand air compressor will have this level of care, though, so be sure to look into the specs if you buy a used machine.

Disadvantages of Buying Used Air Compressors

Of course, when it comes to purchasing used equipment, you get what you pay for. A trustworthy manufacturer and seller will help eliminate some concerns you’ll have about the process. Still, with the advantages of a lower price come these potential disadvantages:

  • Lack of the latest technology: Buying used means you’re getting a machine that probably wasn’t made in recent years. You’d have to sacrifice using the latest air compressor technology in favor of the benefits of buying used air compressors. Not having the latest technology could mean anything from getting equipment that’s less efficient to achieving a slower production and turnaround time than you would with a new system.
  • Unknown life span: When you buy a new machine, you’re guaranteed an estimated life span. When you buy used equipment, it’s hard to know how long the air compressor will last. To combat this, shop with a trusted seller. They’ll provide as much information as possible with a detailed record, if one is available. That record can include information like how well the previous owner maintained the machine and how long they had it. Once you own it, you can get regular audits and maintain it well to sustain its life span.
  • Few warranty options: You may not have as many options for equipment protection with a used system. If something happens to your machinery, you may incur higher costs to make repairs or replacements. This means that, while the initial cost is lower for used equipment, you may end up paying more not long after purchasing your secondhand machinery. You could find used equipment with available or extended warranties, but that will depend on the retailer and machinery.
  • Limited selection: When you buy a used air compressor, you’re limited in your options. You can essentially pick from whatever stock of used equipment a seller happens to have at a given moment. If you’re looking for a particular model, you may need to wait or shop around. If you do want a used air compressor, consider focusing on the specs you need for your job instead of a particular make or model.

Which Option Is Best for You?

With the advantages and disadvantages of both air compressor buying options in mind, you’ll have to decide which will work for your operations. Perhaps reviewing the pros and cons of new versus used air compressors didn’t make your decision any easier. In that case, you should evaluate your unique needs and concerns. Determine whether you should purchase a new or used system by considering:

  • Your initial budget: Your biggest concern will be your budget for the equipment’s initial expenses. While a new unit will almost always cost more than a used one, you should also factor in the cost of replacement parts and repairs a used system might need in the short term.
  • Your budget down the line: If you have an estimate of your long-term budget, incorporate that into your decision. You may be able to afford a higher price tag now, but a used unit could cause financial trouble if your budget ever tightens. Remember that a new machine offers higher efficiency and a longer life span, potentially lowering power and maintenance costs.
  • The amount of air and pressure you need: Consider your operations as you select an air compressor. Don’t compromise on your needs based on the price or advantages of one choice over another. If you need more air at higher pressures, you may consider an option with a large storage tank, which you could find in either used or new varieties.
  • The tools you use: In general, you can operate pneumatic tools more consistently with a large compressor. If you need air purity or a steady stream of lightly pressurized air, consider a smaller machine. You’ll find either of these types available in new and used equipment selections, so remember not to compromise on your operational demands.
  • How often you’ll use an air compressor: Perhaps for your operations, you use an air compressor multiple times throughout the day. In that case, you may want a new machine that will last longer and provide better energy efficiency. If you don’t often use an air compressor for worksite tasks, a used one could be a more cost-effective option for you.

Overall, you may find it’s best to invest in a new air compressor. Of course, the decision is up to you, and you won’t want to spend more than your means to get new equipment. Consider all the factors above, and if you’re having trouble deciding, consult with experienced professionals.

It’s important to follow industry standards for handling air compressors, both for safety reasons and for the sake of optimizing operating costs. Understand how your air compressor works so you can identify any issues and minimize expenses. Evaluate your compressed air needs and use automatic settings, and only use compressed air for its intended purposes to prioritize your team members’ well-being and safety. Make sure everyone on your team understands the operational costs and safety standards associated with using compressed air.

You should fully comprehend your compressed air system — how it’s laid out, what applications it has and when and how to use it effectively. Perform regular preventative maintenance to decrease expenses associated with running it. Below, you’ll learn more about how to enhance your compressed air system’s productivity, reliability and safety.

Working With Compressed Air: How to Use Your Air Compressors Correctly

Learn to implement the best practices for air compressor systems by ensuring worker safety and reducing your operating expenses as much as possible. Which air compressor you choose, how it’s installed and how you use it will determine its effectiveness. For more details on which best practices to follow, keep reading:

1. Purchase the Best Air Compressor for Your Application

Make sure you choose an air compressor well-suited to your needs. Browse various air compressor options and their applications. Different compressor systems are best-suited to various environments. For instance, oil-free scroll compressors are best for pharmaceutical and food manufacturing environments, as they decrease air contamination. Reciprocating piston compressors are best for mechanic and construction industries. For the most heavy-duty applications, a rotary screw compressor is usually a fitting choice.

Think about what your air compressor needs are and which features are most important to you. Educate yourself on different air compressor models and speak with a local expert to seek advice. When it comes to optimizing your use of compressed air, the first step is to make a wise purchase. Make sure you consider what your compressed air needs are and which type of air compressor will best serve those demands.

Ask yourself if your air compressor needs to be oil-free. This means the pistons have a Teflon coating rather than oil lubrication. Oil-free compressors have many benefits — they’re better for the environment, they provide cleaner air and they tend to require less maintenance. When purchasing your air compressor, you can decide between oil-injected or oil-free models.

2. Ensure Proper Installation of Your Air Compressor

Where and how your air compressor is installed will make a huge difference in its operating costs and safe functioning. If you’re wondering how to protect your air compressor from damage, learn about proper placement and installation.

For optimized function, an air compressor needs a consistent stream of cool, dry and clean air. Make sure airflow into the compressor is unrestricted and free from any impurities, with plenty of ventilation. Give the air compressor ample distance from any other equipment, especially machinery that generates hot air. If situated poorly, an air compressor can become a hazard and damage itself as it tries to work.

You should place your air compressor as close to where you need to use it as possible. The further compressed air has to travel, the less efficient it’ll be and the more opportunity there will be for leakage. Be sure to attach a filter and link the compressor to both an air dryer and oil and water separator.

When choosing a placement, also consider noise levels. Since the machine can be noisy as it operates, try to place it somewhere it’ll be least disruptive. If you place your air compressor outside, make sure it’s protected from both water and dirt.

3. Measure Your Compressed Air Needs

Various industries have different applications for compressed air. Evaluate your needs to determine the most effective operational setup. Keep a log of when you use compressed air and how much pressure your demands require. Once you’ve compiled some data, check for peaks and lows. Determine when your need for compressed air is at a high or if there are times when compressed air is unnecessary.

One of the most important ways to decrease operating costs is to turn off the air supply when your compressor is not operating. You’ll want to utilize the system’s storage and automatic controls to your advantage. If your compressed air machine lacks automatic controls — very old models may not have this option — consider upgrading your model. Automatic controls will help you save on operating expenses.

Additionally, you should always use the minimum number of air compressors needed to meet your demand at a given time. Unless your application requires a constant stream of compressed air, shut the supply off when it’s not needed.

Another area of lost efficiency occurs with the pressure level. Be sure to use the lowest practical pressure level for any given application. Excess pressure will increase your expenses, as more pressure requires more power. Using a minimum amount of pressure will decrease both power consumption and the risk of leaks.

4. Understand the Cost of Operation

Compressed air is not free — the purchase price of a compressed air machine is only the initial cost. You need to make sure you understand the operating costs of using compressed air if you hope to employ it productively. In an industrial plant, a compressed air system can account for as much as 30% of your total electric bill, which can be hundreds of thousands of dollars.

Effective use means only applying the necessary level of pressure and turning the airflow off when not using the machine, but it also means understanding compressed air leaks. Leaks result in a huge amount of waste. Generating compressed air takes a lot of power input. You’ll want to use all the compressed air your machine generates and avoid allowing any of it to go to waste through leaks.

Air leaks are an expensive waste of power, but they can also harm an entire industrial operation. Over time, air leaks can slow or even shut down production. They can contribute to system pressure drops, shortening the life span of other equipment. Air leaks force an air compressor to work harder and longer, eating up power and resulting in less efficient operation.

It’s important to understand the operating costs of using compressed air so you can identify and address gaps in efficiency. This is especially true for solving leaks in your compressed air system.

5. Know Where and How to Check for Leaks

To optimize your air compressor, you need to be able to identify any possible leaks. Check for leaks in all these operational points:

  • Overhead distribution
  • Ground-level air hoses
  • Hose connections or fittings
  • Quick couplers
  • Drains
  • Filters
  • Regulators
  • Line lubricators

Several factors can contribute to leaks. If seals, fittings or connections are loose, there will likely be leaks. If other machines or workers bump into the air compressor, they may damage pipes or fittings and cause leaks. Similarly, operator error can result in a leak problem. For instance, someone may forget to close a valve or shut off the machine after use.

The simplest way to identify a leak is to listen for a hissing sound while the air compressor is in operation. If your air compressor is located in a noisy location, such as a factory, you can use an ultrasonic acoustic detector. These tools filter out any background noise and recognize high-frequency hissing sounds that an untrained ear might miss. The tool will alert you of possible leaks either on a visual screen or through connected earphones.

6. Address and Fix Any Leaks

Once you’ve checked for leaks by listening to your air compressor — with or without an ultrasonic acoustic detector — you’ll need to know how to fix any possible leaks. Air does not need much space to escape, and compressed air will exit the system rapidly.

Address leaks by closing off points of escape. This includes loose fittings and connections through which air can travel. This is the primary cause of most leaks. Make sure to tighten any fittings, couplers, valves and other connection points. In addition to loose fittings, another cause of leaks can be small holes in hoses or pipes. You may need to replace elements of your machinery that compressed air travels through. Even the tiniest holes can result in massive amounts of lost air.

Because you might not be able to see where exactly air leaks are coming from, you should upgrade your air compressor system’s components at regular intervals. Replace older hoses and pipes that might have sustained damage and tighten any fittings often, as they may loosen over time.

Create a schedule for when you will check for leaks in your air compressor — you should aim to do this often. Educate everyone on your team about how to identify and avoid leaks.

7. Use Compressed Air Only for Its Intended Purposes

Using compressed air for unnecessary purposes will waste power and increase operating costs, but it can also result in serious injury or death. Compressed air is powerful. At only 2 pounds-force per square inch (psi), you can propel a spitball through a straw up to several yards. Imagine the damage an air compressor operating at 60 to 100 psi can do.

If compressed air enters the body through the mouth or elsewhere, it can rupture organs. If it enters the bloodstream, it can cause a heart attack or stroke. Debris propelled by compressed air can cause severe injury, especially to the eyes and ears. This can lead to blindness or deafness.

To ensure harm-free operation, educate yourself and your team on air compressor safety. Only ever use the machine for its intended purposes. Never used compressed air to clean away debris from a work area or off of clothing. Provide protective gear to anyone working within proximity of an air compressor, and enforce the use of this gear.

An air compressor is not a toy — always prioritize caution. In addition to only using the machine for its intended purposes, evaluate any possible hazards. Make sure outlets are grounded correctly, dangerous fumes release away from workers and compressors have access to clean, dry, cool air.

8. Schedule Regular and Preventative Maintenance

Scheduling preventative maintenance will help you avoid emergency repairs and unexpected downtime. It’ll help you optimize your air compressor’s performance, lengthening its life span and decreasing operating costs. At fixed, scheduled intervals, you should perform the following tasks:

  • Clean the air filter: Your compressor’s air filter eliminates impurities, so it’s important to keep it clean.
  • Check and replace oil filters: Oil buildup will damage compressed air, so be sure to replace heavily coated oil filters.
  • Reapply fresh lubricant: A lack of fresh lubrication will result in corrosion, damaging the machine and its parts.
  • Grease motor bearings: Rust on motor bearings can lead to motor failure.
  • Adjust belt tension and replace old belts: A worn belt may snap during operation, which can cause serious damage.
  • Clean intake vents: Reliably clean input air will make the air compressor’s job much easier.
  • Check performance levels of all parts: Check everything, including oil level, temperature, voltage and vibration.

Without consistent preventative maintenance, an air compressor’s productivity will decrease. In extreme instances, a lack of maintenance can pose a serious threat, as an unserviced air compressor can catch fire or explode. For these reasons, it’s important to follow a schedule for cleaning and replacing elements of your air compressor.

How to Train Your Team

When it comes to operating machinery, never underestimate the importance of proper, regular, in-place trainings. Learn how to train your team so anyone who might come into contact with your air compressor understands how to use it safely and effectively.

Teach your team about the equipment’s operating costs, and make sure everyone knows how to recognize the hissing sound associated with air leaks. Review appropriate and inappropriate uses of compressed air and enforce standards for when and how to use it. Make sure everyone who will be using the air compressor knows how to check the equipment before employing it.

Be sure to provide all necessary protective gear and make it mandatory to wear, including eye and ear protection. Explain the dangers of not wearing this gear so everyone understands the stakes. There are plenty of real-life examples of injuries caused by misuse of compressed air — describe the risk of harm associated with not wearing appropriate personal protective equipment (PPE).

You can use premade training videos to supplement your in-place training. Videos will provide visuals to illustrate key points, but be sure to engage in a conversation with your team before and after showing a video.

After initial training, use posters and checklists to serve as daily reminders. Revisit training materials at pre-planned times to keep the information fresh in your team members’ minds.
