Determining dryer capacity at actual operating conditions
To determine the maximum inlet flow capacity of a dryer at vari -
ous 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 DHP300
handle when compressed air to be dried is at 350 psig and
90°F; ambient air temperature is 80°F?
Answer: 300 x 1.19 x 1.12 = 400 scfm.

Rated capacity (scfm) @ 725 psig inlet pressure, 100°F inlet
temperature, and 100°F ambient temperature and 60 Hertz
operation.
