SIZING
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 model 1000 handle when the compressed air to be dried is at 80 psig and 90°F; ambient air
temperature is 80°F; and a 38°F dew point temperature is desired?
ANSWER: 1000 x 1.17 x 1.12 x 1.0 = 1310 scfm.
Pressure Drop
To determine pressure drop at increased flows, multiply the pressure drop at rated conditions from Table 1 by the multiplier
shown in Table 3 for the appropriate air flow rate and operating pressure.
EXAMPLE: What is the pressure drop across a model 1000 when flowing 1500 scfm at 200 psig ?
ANSWER: 1500/1000 = 1.5; multiplier below at 1.5 and 200 psi = 1.1; 1.1 x 4.2 psi = 4.6 psi.
