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 an air-cooled model 360 handle
when compressed air to be dried is at 200 psig and 110°F;
ambient air temperature is 80°F?
Answer: 360 x 0.95 x 1.12 = 383 scfm.

*Air-cooled models; water-cooled models use 1.15 multiplier if cooling
water is below 35°C, 95°F.
3.0 MAINTENANCE
3.1 Condenser coil – Clean off accumulated dust
and dirt monthly.
3.2 Moisture separator – Replace filter element
when pressure drop across dryer is excessive,
or annually, whichever occurs first.
3.3 Check separator daily to be sure automatic
drain is discharging.
3.4 Blow down separator weekly.
3.5 Rebuild drain mechanism annually.
To facilitate service, maintenance kits are available.
