We’ve put together a complete guide to rotary screw air compressors to help you see if these machines would work for your operations. Learn more about this equipment, from how it works to the industries that use it.

What Is a Rotary Screw Air Compressor?

A rotary screw air compressor uses screw mechanisms to compress air by reducing the volume air takes up. It’s just one type of air compressor available for use in various industries and purposes. Because of their mechanisms, these machines are occasionally called “twin screw compressors.” Industries that require large volumes of high-pressure air often choose a rotary screw compressor for their operations.

How Rotary Screw Compressors Work

Rotary screw air compressors use positive displacement, a process that involves pulling air into a chamber. It reduces the volume in the chamber to compress the air. Rotary screw air compressors, specifically, utilize positive displacement with spiral screws. The screws produce a hydraulic seal to compress the air. For an oil-flooded system, which is the more common type of rotary screw compressor, the process of compressing air involves these steps:

  1. Air enters the machine: Air around the system enters it through the inlet valve. Ideally, this will be clean air free of excessive dust, dirt or debris, but it will depend on where you keep the machine.
  2. Air travels through the machine: The air moves through the pressure control line. It goes through the regulator valve, which sets the air pressure.
  3. Oil and air enter the compressor: Oil and air move into the compressor to combine into a mist.
  4. The air compresses: The air compresses as it travels the matching rotary screws.
  5. The air exits the compressor: The air and oil mist leaves the compressor and enters an oil separator tank.
  6. The air and oil separate: Centrifugal force brings the oil molecules together, causing them to separate and fall to the tank.
  7. The system filters the oil: Oil moves to an oil cooler then a filter to remove any debris. The oil returns to the air compressor to be used again for the next batch.
  8. The system purifies the air: The air moves to a second filter, purifying the air for your needs and removing more oil.
  9. You use the air: The compressed and oil-free air moves into a reserve tank for later use or into your connected machines and tools.

Natural gas compressors are machines that compress natural gas by increasing the pressure and decreasing the volume of the gas. There are several different types of natural gas compressors, and they come in different sizes and are designed for various industries and purposes. Natural gas compressors differ from natural gas air compressors, which are machines that compress air but use natural gas as their fuel source. These compressors also have many commercial and industrial uses. This guide covers everything you should know about both natural gas compressors and natural gas air compressors.

Difference Between Air Compressors and Natural Gas Compressors

First, it’s important to understand the difference between air compressors powered by natural gas and natural gas compressors. These are two different types of machinery used for very different purposes.

Air compressors are devices that convert power or fuel into potential energy in the form of compressed air. These machines can be powered by electricity, natural gas, gasoline, diesel or other fuel sources. Air compressors are used for many applications, including filling air tanks and tires, powering pneumatic tools and more.

On the other hand, natural gas compressors are machines that compress the natural gas itself. The gas is compressed mechanically, in stages, to different pressurization amounts to meet the desired level for delivery. Compressed natural gas is used in various industries for different purposes.

Natural Gas Air Compressors

Air compressors are available in several shapes and sizes and are used in different applications in many industries. Two common types of air compressors use natural gas or electricity as fuel. Natural gas air compressors use natural gas to power the air compression process and are versatile pieces of equipment.

Difference Between Natural Gas and Electric Compressors

Natural gas-powered air compressors and electric air compressors are two of the most popular types of air compressors on the market today, and both have different uses and industries where they are most useful. The main difference comes from the fuel source that powers the air compressor. Electric air compressors are powered by electricity and must be plugged into an electric outlet to work. Natural gas air compressors are powered by natural gas and can be hooked up to a natural gas line or a portable natural gas tank.

Both natural gas air compressors and electric air compressors have some pros and cons, and the best air compressor for your industry or company depends on the type of work you need it for and other factors. Natural gas compressors are generally more versatile and portable and boast higher energy efficiency and lower energy costs. However, they can also be louder to run and give off exhaust that requires proper ventilation.

Electric air compressors can work in just about any setting where there is access to electricity. They are quieter to run and can run continuously without needing to stop and refuel. The downside to electric compressors is that they generally have a higher operating cost due to lower efficiency and the higher cost of electricity. They are also limited by power outages and cannot work if the power goes out, while a natural gas compressor can keep working even during a power outage.

Benefits of Natural Gas Air Compressors

Natural gas air compressors have many benefits over other types of air compressors, including electric air compressors. The benefits of natural gas compressors include:

  • Lower energy costs: With electricity costs consistently surging higher, natural gas air compressors are a smart way to save on electricity costs. These air compressors are powered by natural gas, which greatly reduces the electricity needed and, therefore, can save a lot of money for a facility that uses air compressors. Natural gas is a very affordable energy source, and experts predict it will decline in price for the next 15 years.
  • Versatile for remote work: With a natural gas air compressor, there’s no need to be constantly attached to an electrical power source, so you can use your air compressor on remote job sites and other areas where finding electricity may be a problem. They can also move across job sites, providing compressed air in different locations without needing to be stationary and plugged in.
  • High efficiency: Air compressors powered by natural gas offer a high-efficiency workload, even without a full tank. These compressors are heavy duty and work for various applications.
  • Better heat recovery: Many natural gas air compressors can make use of the excess heat recovered from the cooling jacket as well as the gas exhaust. This makes natural gas air compressors much more efficient than other types.
  • More environmentally responsible: Natural gas is a very efficient fuel source, produces almost no carbon monoxide and less carbon dioxide than other fuel sources like oil and coal.
  • Reduces the risk of sparks: Other types of air compressors are more prone to sparks, which can be incredibly dangerous in certain industries. But natural gas air compressors have a far lower chance of sparking, providing additional safety.

Natural Gas Compressors

Natural gas is a fossil fuel source that formed deep beneath the surface of the earth. Natural gas contains a large amount of methane, as well as other components like hydrocarbon gas liquids, carbon dioxide and water vapor. This natural fuel source was formed millions of years ago from plant and animal matter and is now found in the cracks and spaces between layers of rock, beneath the earth and under the oceans. The natural gas is extracted from these natural stores and sent through a system of pipelines to compress it, store it and eventually transport it to consumers, either in tanks or through direct pipelines.

To make natural gas easier to transport and distribute properly, companies use natural gas compressors to reduce the overall volume of the gas. With compression, the natural gas can move along more easily and in greater quantities. Different types of natural gas compressors may be used at different stages in the pipeline, from extraction to distribution to the end consumer. This is because the gas may lose pressure due to the friction and distance of travel.

Benefits of Natural Gas Compression Services

Natural gas compression services are necessary to safely and effectively extract and transport natural gas to the end consumer, sometimes over very long distances. The main benefits of natural gas compression services include:

  • Gas distribution: Once a store of natural gas has been tapped, compression helps the gas flow upwards from the wells and into storage or a distribution network. Additionally, compression used during the transport of natural gas is often considered a lifeline to the distribution system.
  • Separation and filtration: An essential component of compression services is the separation and filtration of natural gas. This is necessary to remove any impurities and keep the high quality of the natural gas. Natural gas compressor filters are used at multiple points throughout the natural gas pipeline. As the gas travels, it can collect condensation, which then needs to be filtered out to maintain the purity of the natural gas.
  • Maintains consistent pressure: When the natural gas pipelines extend over great distances, different terrain elevations can cause differences in air pressure. Compression services used throughout the pipeline ensure that the natural gas maintains a consistent and safe pressure as it travels. Additionally, these services provide the correct sizing of the pipes to maintain the right pressure while transporting large quantities of natural gas.

Industries That Use Natural Gas

Natural gas has many industrial purposes, from providing an energy source to power machinery to being a main ingredient in manufacturing products like plastics, fertilizers, anti-freeze and fabrics. However, most natural gas is consumed by a small number of industries, including the following:

  • Paper and pulp
  • Metals
  • Chemicals
  • Petroleum refining
  • Stone, clay and glass
  • Plastics
  • Food processing

Among these industries, natural gas serves many purposes, including heating, cooling and cooking, just as in residential and commercial uses. It’s also used for treating and incinerating waste matter, preheating metals like steel and iron, drying and dehumidifying, melting glass and fueling industrial boilers. Natural gas can also be separated into various other gases and chemicals for use in manufacturing. Butane, ethane and propane all come from natural gas and can be used for various purposes.

In addition, natural gas is used as a gas desiccant system in which the natural gas serves as a dehumidifying product for industries that manufacture pharmaceuticals, plastics and even candy. The natural gas controls the moisture level in the air and protects the integrity of the products.

Natural gas compression services are important to many industrial uses, including:

  • Gas lift
  • Reinjection of gas to maintain pressure
  • Gas gathering
  • Gas processing operations
  • Transmission and distribution systems
  • Controlling gas volume for shipment and storage


How Does a Natural Gas Compressor Work?

There are two main types of natural gas compressors used for industrial purposes — reciprocating and screw compressors. These two types of natural gas compressors work in different ways to compress the gas.

1. Reciprocating Compressors

A popular choice across many different industries that use compressed natural gas, reciprocating compressors use crankshaft-driven pistons and positive displacement to compress the gas to the correct pressure. There are three main stages in the functioning of the most common types of reciprocating compressors:

  • Stage 1: In the first stage of gas compression, the natural gas enters the machine through an inlet and passes through a scrubber where any liquids fall out and can be drained away. Then, the crankshaft-driven pistons push and compress the natural gas, increasing the pressure and temperature of the gas. The gas is then pushed through an intercooler, which helps to cool down the gas again. The heating and cooling processes allow for more condensate to fall out of the gas, so it goes through another scrubber for the liquids to collect.
  • Stage 2: In the next stage, the natural gas is again pushed along with another piston to increase the pressure further. This also raises the temperature again, so the gas then goes through the intercooler to drop the temperature lower. And, just as in the first stage, the heating and cooling of the gas cause some more liquids and condensation to fall out in one last scrubber.
  • Stage 3: The natural gas goes through one more stage before the compression process is complete. In this stage, the piston again pushes the natural gas to compress it even further and increase the pressure even more. Again, the temperature rises with the increase in pressure, so the gas is pushed through the intercooler one last time. Some industries use an additional scrubber to remove even more condensate, but this is less common.

2. Screw Compressors

Another type of natural gas compressor is a screw compressor. These compressors use a pair of helical screws or rotors, aligned side by side, to spin and compress the gas. The natural gas enters the inlet with suction and moves around the threads of the screws, which compresses the gas as it goes through the machine. The gas is discharged on the other side of the unit at a higher pressure. Screw compressors are generally used in industries and businesses that don’t require as high of gas pressure or as high a volume of gas.

Sizes of Natural Gas Compressors

Natural gas compressors are available in a range of sizes to fit different industrial jobs. Smaller, single-stage compressors are used for lower volumes and pressures of natural gas and may be used to gather vapors and fugitive gases. Medium-sized compressors are often found at wellheads and gathering systems, as well as many other industrial uses. The largest natural gas compressors use several stages and are most often used at compressor stations along a pipeline that transports large quantities of natural gas.

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.

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.

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


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.


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.
