VACUUM PUMP SIZING
The main function of a vacuum pump is to either handle air leakage and/or non-condensables from the process, or to evacuate a chamber from atmospheric pressures to a certain vacuum level. Often the air or non-condensable will be saturated with water or other process vapors. CALCULATION AND MEASURMENT OF INLET CAPACITY SCFM = Capacity measured at standard conditions (14.7 psia – 29.92” Hg – 760 Torr at 68o F) ACFM = Capacity measured at inlet conditions = SCFM X 760 / P X T / 530 ACFM = W X 359 / MW X 760 / P X T / 492
