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 a 60 Hz air-cooled model 1000
handle when compressed air to be dried is at 200 psig and 100°F;
ambient air temperature is 80°F?
Answer: 1,000 x 1.22 x 1.12 = 1,366 scfm.

temperature, and 100°F ambient temperature.
