How to tell a good air compressor? Determine which one requires the highest CFM at the highest PSI. Add 50% to the required CFM for a margin of safety, and look for a compressor that meets the requirement. For example, if a tool requires 3 CFM at 90 PSI, select a compressor that delivers at least 4.5 CFM at 90 PSI.
What should I look for in an air compressor? There are three key aspects to consider when it comes to choosing an air compressor: air pressure, air flow (measured in cubic feet per minute, or CFM), and the amount of air that can be stored in the tank.
