PSI = pressure in pounds/square inch
CFM = air flow in cubic feet/minute


+ pressure loss is too great and therefore the combination of Hose Size, CFM, and Gauge Pressure is not recommended. Gauge
Pressures the indicated air pressure in pounds/square inch, at thesource (i.e. the air compressor receiver tank)
