What is CMF?

 


Cubic Feet per Minute (CFM) is a measurement describing how much air pressure a compressor can produce at a given pressure. This is often called the compressor’s flow rate, and it determines what kind of air tools you can use with the compressor. The higher the CFM of a compressor, the more it is capable of.

Also, the higher the CFM rating, the larger the tank size. This is because continuous use tools generally require a higher CFM rating. When operating a high CFM tool on a compressor with a small tank, the compressor will need to cycle on more often, which could mean more downtime using that tool.  

For example, say the air tool you’ll be using with the highest CFM is an air-powered drill that requires 4 cfm at 90 PSI. Multiply 4 by 1.5 to determine the CFM rating of the air compressor you’ll need. In this case, you’ll be looking for an air compressor capable of delivering 6 CFM at 90 PSI.
