The following is a basic pressure relief procedure. Be 
sure to follow the specific pressure relief procedure in 
your spray gun and/or fluid supply equipment manuals.

1.

Close the main air shut-off valve.

2.

Trigger the gun or dispense valve and open any 
drain valves to relieve pressure.

To maintain maximum filtering efficiency and avoid 
excessive pressure drop, the filter must be kept clean. 
See Manual 309919 for cleaning and parts information.

See Manual 309919 for operation, cleaning, and parts 
information.

Be sure air to the regulator is clean. Erratic operation or 
loss of regulation is usually caused by dirt in the regula-
tor. See Manual 309924 for cleaning and parts informa-
tion.

Wet air enters 
membrane module

Water vapor purges

Clean, dry air 
exits module

Water vapor permeates through 
hollow membrane fibers

To avoid injury, relieve air and fluid pressure before 
checking, cleaning, or repairing the equipment.

•

Relieve the pressure before cleaning, checking 
or repairing equipment. Follow Pressure 
Relief Procedure, above.

•

Check system at least once per shift to ensure 
proper drainage.

It is recommended that Air Filter 234402 be 
installed upstream of the coalescing filter to 
remove 3 micron and larger size particles and sep-
arate large droplets of moisture from the air line.

Never let the liquid level in the bowl reach the base of 
the coalescing element.
