Determining dryer capacity at actual operating conditions
To determine the maximum inlet flow capacity of a dryer
at various operating conditions, multiply the rated capacity
from Table 1 by the multipliers shown in Table 2.
Example: How many scfm can an air-cooled model 1.5 handle
when compressed air to be dried is at 200 psig and 100°F;
ambient air temperature is 80°F?
Answer: 160 x 1.22 x 1.12 = 218 scfm.
