Air compressors can be used for a wide range of applications in the automotive industry. Pneumatic tools make auto repair and body work easier when paired with the correct compressor, but how do you choose an air compressor best suited for your application?

Choosing an Air Compressor for an Automotive Shop

When deciding on an air compressor for an automotive shop, you first need to define how the air compressor will be used. You want to match the specs of the air compressor to your needs. Taking the following questions into consideration will help guide you to the right air compressor choice.

What air pressure and CFM do you need for your tools or sprayers?

Each tool is rated to use a specific amount of CFM at a certain PSI. For example, a paint spray gun may require 5 CFM at 70 PSI, where as a 9” grinder may use 17.5 CFM at 90 PSI. Doing an audit on tools each technician uses, in addition to the average amount of time the tools are used, will help determine the size of compressor needed. Mi-T-M offers both 80-gallon and 120-gallon simplex and duplex models at 5 to 15 horsepower; 18 to 93 CFM at 175 PSI.

What is your power source for the air compressor?

It’s important to know what phase and voltage power your location has. Do you have 230V 1Ø or 460V 3Ø? The air compressor you choose needs to match in order to work properly. Consult an electrician to verify which phase and voltage power you have.

How much space do you have allocated for the compressor?

It is important that air compressors are receiving a steady supply of air, so you want to make sure you have an open, ventilated space for your air compressor. Mi-T-M offers horizontal and vertical 80-gallon and 120-gallon compressor options perfect for automotive needs.

Is there a need for multiple ports?

If you have several mechanics, you will benefit from a compressor with multiple outlets for connecting tools at separate work stations.
