What size air compressor do I need for my shop?
To get a feel for how much air (CFM) you will need, you can figure roughly 4-5 CFM per person in an automotive shop and 12-15 per person in a body shop. Once you determine the CFM you need, take that figure times 1.25 and use that total CFM to choose your compressor.
What is the maximum operating shop air pressure?
Typical maximum operating pressures for body shop air compressors are available in standard pressure settings of 115 pounds per square inch (or psi) or 145 psi or 175 psi. Each pressure variation has a “cut-in” pressure where it starts making air, and a “cut-out” pressure where it stops making air.
What is a typical maximum working pressure for an air compressor?
Most compressed air equipment is designed to operate at around 90 – 100 psi (6 – 7 bar). For this reason, most people only need a compressor with a maximum pressure of 7 bar.
What is the difference between single stage and 2 stage air compressor?
The fundamental difference between a single and two-stage air compressor is the number of times the air gets compressed. In a single-stage, the air is compressed one time; in a two-stage, it is compressed twice for double the pressure.
What is the usual air pressure in a shop compressed air system?
100 psi
The most common pressure rating of standard air compressors was 100 psi, so typical operation needed to be slightly lower. But over the years, plant pressures have crept up, now often reaching levels of 120 psi (8.3 bar) or higher.
Is a two stage compressor worth it?
Are Two-Stage Air Conditioners Worth It? If you have the upfront budget, a two-stage air conditioner is more efficient across the board. It reduces energy consumption and has better control over temperature and humidity—but not everyone can spend extra money.

What is the advantage of a larger tank on an air compressor?
A larger tank holds more air and will allow you to use more air before the pressure drops and the motor kicks on to refill the tank. That might let you avoid stopping work while the compressor refills the tank.
