Servicing the Regulator and Coalescing Air Filters
Servicing the air filter consists of cleaning and/or replacing the air
filter, sediment bowl, and gasket. You can obtain replacement parts
for these items from the air controls manufacturer.
Warning
Turn off all power to your system before attempting any repair
procedure. See Before You Perform Any Maintenance Procedure, at
the beginning of this section.
1. Turn off the air flow control valve and depressurize all
connected air lines.
2. Remove and clean the sediment bowl. If your unit contains a
polycarbonate bowl, inspect it for cracking or cloudiness; if
present, replace it.
Warning
Cracked or cloudy polycarbonate bowls can explode when
repressurized, causing serious injury.
3. Clean other parts using soap and water.
4. Dry the bowl and other parts, and blow out internal passages
in the body using filtered, dry compressed air.
5. Using filtered, dry compressed air, blow through the filter
element from inside to outside to dislodge surface contami-
nants. If the filter element is plugged, replace it.
6. Apply a light coating of Dow Corning 44M grease (or equiv-
alent) to the bowl gasket, and reassemble.
