Air Compressor CFM Sizing

About

Struggling to figure out the right compressor size or pipe diameter for your pneumatic tools? Tired of pressure drops killing tool performance at the end of long pipe runs? This calculator solves both problems in seconds. Enter number of tools, CFM per tool, usage factor, system pressure, pipe length, and allowable pressure drop. Calculates total CFM demand, compressor HP requirement, recommended pipe size, and actual pressure drop. WHAT IT CALCULATES: - Total air demand in CFM - Required compressor horsepower - Recommended pipe diameter - Pressure drop across the run - Allowable vs actual drop comparison KEY FEATURES: - Multiple tool entries with individual duty cycles - Standard pipe sizes from 1/2 to 4 inch - Equivalent length for fittings - Works completely offline - No account or login required Built for plant engineers, maintenance techs, and contractors running compressed air systems.
