Capacity Correction Factors

To adjust the dryer capacity for non-standard conditions, use the Capacity Correction Factors (multipliers) from the tables below.

Sizing Example
What is the capacity of a RGD100 at 100°F inlet air temperature, 150 psig working pressure and 110°F ambient air temperature?

Answer
100 scfm (rated flow from RGD specifications table) × 1.08 (correction factor for inlet air temperature, table 1) × 0.94 (correction factor for ambient air temperature, table 2) = 102 scfm
