This handy chart can help you find out how much CFM you will need from your air compressor to run various air tools. CFM is simply the Cubic Feet per Minute that a particular tool needs to operate. It is a measurement of volume. Generally the larger the tank on an air compressor the more CFM it can produce. To use this chart, you will need to know the PSI (Pounds per Square Inch) and CFM that a particular air tool operates and then look to see if your air compressor can power it. The majority of air tools operate in the 90 to 100 psi range and most air compressors from the smallest to the largest can easily produce this much pressure. The real deciding factor in selecting the proper size air compressor is the CFM that it can produce.
