Remove the water vapor from compressed
air prior to distribution through the air
system. Check operation of aftercooler and
moisture separator. Install a compressed air
dryer sized for the flow and dryness level
required. (Note: Filters may also be required
to remove particulates, liquid oil aerosols or
for oil vapor removal. Change cartridges as
recommended by the filter manufacturer).
Check all drain traps routinely to insure their
proper operation. Maintain them regularly.
Defective Drain Solenoid Valve Ensure valve opens and closes as signaled
