Clean Air Filter/Regulator/Drain
The air filter/regulator with auto drain requires
periodic cleaning to maintain maximum filtering
efficiency and to avoid excessive pressure drop.
The cleaner the compressed air supply, the less
maintenance will be required. A visible coating
of dirt or condensate on the filter element surface
or excessive pressure drop is an indication that
cleaning is necessary.

filter/regulator, turn off the air
supply and depressurize the
system and filter.
