Air Quality Check

Single Stage Filter/Regulator Maintenance

Even using air which has some oil and water in it, the AutoPump System should operate
trouble-free for years. The air filter is normally a 5 micron filter with a replaceable
element.
To replace the element in the air filter on the single stage filter/regulator use the following
procedure:
STEP 1 - Disconnect Air Source
• Valve off the air supply and drain the downstream air to the air filter.
Or disconnect the blue system air supply hose from the single stage
filter/regulator. The air filters will depressurize, allowing them to be
safely serviced.
WARNING:
Do not remove a filter bowl that is pressurized.
