What Is SCFM on an Air Compressor?

By Staff WriterLast Updated March 25, 2020

SCFM, which stands for standard cubic feet per minute, is a numerical rating that shows the quantity of air flow a pneumatic tool requires to function at peak performance. The actual value varies based on the pressure exerted by the air in the compressor, which is typically measured in pounds per inch.

Air tools often need a vast amount of air volume to operate at a high-performance level. Bigger and more powerful tools require at least 10 SCFM, while smaller devices need around 0 to 5 SCFM. Another performance rating for an air compressor is the HP or horsepower rating, which shows a tool’s motive power.
