AIR FILTER
FIGURE 6–1 – HEAVY DUTY AIR FILTER
HEAVY–DUTY AIR FILTER (FIGURE 6–1) furnished
as standard equipment on units with an enclosure is a
heavy–duty washable element dry type air filter. The
air filter must receive proper maintenance if maximum
service is to be obtained from the unit. Establishing ad-
equate and timely filter service is MOST IMPORTANT.
An improperly maintained air filter can cause a loss of
compressor air delivery.

”CHANGE AIR FILTER” LED is illuminated. Clean ev-
ery 50 to 150 operating hours depending on dust con-
ditions.
Use only genuine Gardner Denver air
filter elements on Gardner Denver
compressor units. Genuine parts are
available through your authorized
Gardner Denver distributor.

Inspect the element for ruptures or cracks in the
pleated media; replace the element if any are
found. Inspect the gasket on the bottom (outlet

damaged, ruptured or wet. Never use
gaskets that won’t seal. Keep spare

duce downtime. Store elements in a
protected area free from damage, dirt
and moisture. Handle all parts with
care.
