Question: how many scfm do i need?
Answer: More important is the Required SCFM or Standard Cubic Feet per Minute. All air tools will have a required SCFM, but in general smaller air tools require between 0-5 SCFM. While larger tools can need 10 or more SCFM. CFM stands for Cubic Feet per Minute and is the volume of air the compressor can pump out per minute.
