Air flow capacity = Nominal capacity of dryer x Factor F1 x Factor F2 Example: A CHD-500 has a nominal capacity of 500 SCFM. What is the maximum allowable flow through the dryer at following operating conditions? Air Inlet Pressure: 110 PSIG (7.6 BARG) F1 = 1.04 Air Inlet Temperature: 105° F (40.50° C) F2 = 0.93 Air flow capacity = 500 x F1 x F2 Air flow capacity = 500 x 1.04 x 0.93 = 483.6 SCFM This is the maximum air flow rate that dryer can accept under those operating conditions. How to Select a Suitable Dryer for a Given Capacity Minimum Std. Air Flow = Design Air Flow / Factor F1 / Factor F2 Example: Given the operating parameters below, find a suitable dryer.
