Question: how much scfm do i need?
Answer: Look for the “SCFM at 90psi” number when comparing SCFM ratings. Smaller tools usually require between 0-5 SCFM, while larger tools can require 10 or more SCFM. To gauge the minimum compressor SCFM rating you need, examine the SCFM requirements of all the tools you intend to use.
