how to install an air compressor in your garage

For people who use a variety of power tools, air compressors make operations much easier. In contrast to the sweat and strain that often goes into the manual use of wrenches, saws and hammers, an air compressor combined with pneumatic equivalents can make such applications feel relatively effortless. As such, air compressors have grown in popularity for all types of power-tool applications.

Just as factories and manufacturing plants continue to build more elaborate compressed-air systems, the technology is also being adopted for home use by independent craftspeople, making a wide variety of projects much easier.

While it’s relatively easy to install an air compressor in a residential garage, some basic things should be understood about machine capacity and your air tool requirements.

The Five Crucial Specifications of an Air Compressor

Air compressors vary in terms of capacity because different machines are built for different levels of operation. When it comes to air compressor installation in your home garage, there are five main things to consider in the model you choose:

Cubic feet per minute (cfm)

The most important quality of an air compressor is its cfm rating, which determines how much air is produced by the compressor. All pneumatic tools demand certain levels of cfm, and an air compressor must be able to meet all of the demands for the tools in your arsenal.

For example, with a compressor rated 9.0 cfm, enough air will be generated each minute to power a wrench that demands 5.0 cfm. However, a tool that demands twice as much cfm will need a higher capacity compressor of 14 cfm or more.

Pounds per square inch (psi)

The pressure at which air is delivered from a compressor — measured in terms of psi — is another critical factor in the ability of an air compressor to power pneumatic tools properly. Certain tools demand higher psi than others, and an air compressor must exceed the maximum rating from a given set of tools to cover the owner’s working needs.

The majority of popular garage tools demand 90 psi. However, psi ratings must be read in conjunction with cfm ratings, which are a larger indicator of whether a compressor can handle the demands of a particular tool. As a rule of thumb: the greater the cfm and psi rating of a machine, the broader the range of tools that can ultimately be powered.

Horsepower

The measure of an air compressor’s motor output. Though significant, the cfm and psi ratings of a unit are better indicators in the overall power. As the two ratings increase, so too does the horsepower.

Tank volume

The amount of compressed air a specific model can hold at a given time is also important. The greater the holding capacity, the easier it is on the motor during each usage cycle — especially during projects that alternate between active and idle modes. Tank volume indicates the holding capacity of the air compressor.

Duty cycle

Another crucial factor is the length of time an air compressor can run before shutting down to cool. Generally speaking, a compressor should have a duty cycle of 50% or more to operate tools that involve prolonged applications, such as saws and grinders. Additionally, a compressor needs a sizable motor and tank to run cycles of sufficient length for those applications. It’s also important to consider your garage’s power rating. Beware to select a compressor that can be operated at the correct voltage. Always consult with a licensed electrician to ensure proper selection and installation requirements.

How to Install an Air Compressor in Your Garage


Once you’ve selected and purchased an air compressor of sufficient capacity, it’s time to set the unit up in your garage. While the process is more complex than a simple plug-in operation, it can be broken down into the following steps:

  • Select an area for the compressor to stand.
  • Determine how much room will be needed for work and tool applications.
  • Select sufficient hose lengths and fittings for the attachments.
  • Set the compressor on isolator pads to stabilize and lower noise from vibrations. Read the owners manual to follow proper start-up and commissioning procedure.
  • Power the compressor from a nearby outlet.
  • Activate pneumatic tools.

 

The selection of hoses is critical for the power and efficiency of pneumatic applications. Consequently, one of the biggest mistakes users often make is to link industrial-length hoses to small, compact air compressors.

Choose Proper Hoses

Excessively long hoses in garage-sized work spaces can lead to air loss between the compressor and tool tip. In residential garages, compressed air can be utilized much more efficiently with a flexible 50 ft. hose, which provides plenty of length for any system setup that might extend from the garage space to the driveway, living area or backyard. To accommodate the widest range of tool applications, be sure the hose in question has a capacity of at least 150 psi.

Attach a Filter

Between the inlet valve, pistons and tank, certain amounts of moisture can get through in the compressed air. Additionally, oil can make its way from the compressor’s motor to the air tank. For applications such as sanding, painting and blowing, moisture and lubricant can be problematic. Therefore, an air compressor should be equipped with a filtration device at the air outlet. This will prevent condensation from diluting certain pneumatic applications and also stop lubricants from ruining paints and finishes.

Add a Dryer/Separator

For added protection against moisture and other fluids, be sure your air compressor setup is linked to an air dryer and oil/water separator. The two devices can be linked with a short airline between the outlet of the dryer and inlet of the separator.

How to Install an Overhead Tee Extension for Your Air Hoses

For overhead applications in crowded workspaces, additional setup features can solve the problem of dragging hoses. If you intend to work on cars within your garage, for example, hoses could be an inconvenience as you circle vehicles from front to back. To prevent pulls and entanglements, consider installing an overhead apparatus that will link at the far end to your compressor and at the near end to your tools. The apparatus can be set up as follows:

  • Attach a metal Tee extension to a thin 1 to 2 ft. board.
  • Attach the board at a vertical angle to the truss of your garage. The board should be high enough to avoid head bumps, but hang low enough to reach.
  • Attach AIRnet copper or galvanized piping to the outlet that points toward the compressor.
  • Attach quick connect fittings to the bottom outlet.

 

Average CFM Requirements for Air-Powered Garage Tools

There are a variety of applications that can be performed with a garage-based compressed air system. From cutting and sawing to nailing and riveting. These tasks would otherwise require considerable hand coordination and arm strength but can now be accomplished quickly with pneumatic tools, which can be powered by portable, compact, vertical or horizontal air compressors. However, the compressor you choose must provide sufficient cfm capacity combined for every tool you intend to employ in your arsenal.

The following common garage-oriented pneumatic tools — all of which require 90 psi — generally correspond with the following cfm requirements:

  • Air Hammer. 3 to 11 cfm. A multi-purpose tool that can be used for stone carving and metal cutting, and can even be affixed with other tools for cutting and splitting hard objects.
  • Brad Nailer. 0.3 cfm. For projects that require joining pieces together without the imposing sight of nail heads or nuts and bolts, a brad nailer allows you to apply fasteners that are thin and unassuming.
  • Circular Saw. 12 (8”) to 17 (12”) cfm. The circular saw is most commonly used for cutting wood, but it can also be used for other materials with the correct blades.
  • Die Grinder. 4 to 6 cfm. Rivet holes in adjoining metal panels can sometimes be mismatched, but the problem can be solved with a die grinder, which widens metal holes with either a round or pointed rough tip.
  • Drill. 3 to 6 cfm. Holes can easily be formed in wood as well as metal with a pneumatic drill, which instantly penetrates surfaces, thereby drastically lowering the possibility of crooked hole formation caused by manual drilling.
  • Framing Nailer. 2.2 cfm. The hassles of nailing are eliminated with a pneumatic nailer, which penetrates materials in seconds. No more stubborn surfaces, and no more bent nails.
  • Grease Gun. 4 cfm. An asset when it comes to applying lubrication in hard-to-reach areas of engines and machines. It lessens the mess out of grease application.
  • Hydraulic Riveter. 4 cfm. For metal projects, rivets often take the place of screws when it comes to fastening panels together. A hydraulic riveter sets these fasteners into place in seconds.
  • Impact Wrench. 2.5 to 3.5 (3/8″), 4 to 5 (1/2″), 10 (1″) cfm. Removing nuts from engine parts can be accomplished in seconds with a pneumatic impact wrench, which can instantly unfasten bolts that may never be pried loose manually.
  • Needle Scaler. 8 to 16 cfm. A unique tool for sanding metal as opposed to wood, the scaler consists of needles that cut and grind away at rust or barnacles, which can form on metal surfaces through years of exposure to the elements.
  • Orbital Sander. 6 to 9 cfm. Smooth, streak-free surfaces can be created with an orbital sander, which works in randomized motions that prevent grain marks from forming in one direction or another.
  • Shears. 8 to 16 cfm. Cutting through metal with pneumatic shears can be as easy as using an X-acto knife to cut paper. This tool can be used to slice metal for cabinet making, panel resizing or even art projects.
  • Socket Wrench (Ratchet). 2.5 to 3.5 (1/4″), 4.5 to 5 (3/8″) cfm. Long-fastened nuts that are stubbornly held in place can be removed easily with a socket wrench, which has the power to unfasten some of the tightest, rusted-on nuts.
  • Speed Saw. 5 cfm. The task of sawing becomes much easier with the air-powered equivalent of the manual tool. With a pneumatic speed saw, cutting occurs so quickly and effortlessly that there’s little risk of shaky-handed unevenness.

 

Air tools make it possible to perform complicated, heavy-duty tasks in just a fraction of the time it would take to perform such tasks with manual tools. Whether your hobby or trade involves fixing furniture, making sculptures or repairing cars, it can all be done in fewer hours or days along with less physical effort when your garage is equipped with a properly sized and installed air compressor.
