SECTION 6
AIR FILTERS
AIR FILTER – The air filter furnished as standard
equipment is a panel type washable filter. The air filter
must receive proper maintenance if maximum service
is to be obtained from the unit. Establishing adequate
and timely filter service is MOST IMPORTANT. With
wide variation of dust conditions encountered, only ex-
perience can determine the proper time element for
servicing filters. Although a paper filter element is nor-
mally considered expendable, proper and careful
cleaning can extend its original life several times.
Filter Element – Service the air filter element when the
“CHANGE AIR FILTER” LED is illuminated. Clean ev-
ery 50 to 150 operating hours depending on dust con-
ditions.
To service:
Remove louvered filter cover and filter element by re-
moving the six (6) cover to enclosure screws.
Two methods of cleaning are recommended. Use of
compressed air is effective when the major contami-
nant is dust. Washing is effective on carbon, soot, and
oil laden elements.
DO NOT ATTEMPT TO CLEAN ELEMENTS BY
BEATING OR RAPPING.
When air is used, direct a jet of air (100 PSI maximum)
against the clean air side of the element in the opposite
direction of normal air flow. Move the air jet up and
down the pleat, slowly moving across the face of the
element. The nozzle must be kept at least one inch
away from the element. Take care that the paper is not
ruptured by the nozzle or air jet.
When cleaning by washing, use a good non–sudsing
detergent and water. Soak the element in a solution of
two (2) ounces of detergent per gallon of water (140
_
F
maximum) for at least 15 minutes. Swish the element
around in the solution (2 minutes) to help remove dirt.
Warm solution gives best results. Rinse the element
with a stream of water (40 PSI maximum) opposite to
normal air flow until rinse water is clear. DRY THE ELE-
MENT THOROUGHLY BEFORE USING. DO NOT
USE LIGHT BULBS FOR DRYING. Warm air (160
_
F
or less) must be circulated as high surface tempera-
tures can burn or scorch the filter paper.
After cleaning, thoroughly inspect the element for dirt
on the clean air side, holes or damage, by looking
through the element toward a bright light. Do not reuse
damaged elements.
Filter Element Life – The element should be replaced
after six (6) cleanings or if:
1.
Visual inspection indicates a rupture, crack or pin
hole in the pleated media. Inspection should be
done by placing a bright light inside the element.
2.
Pressure drop through a filter with a freshly
cleaned element is below three (3) inches of water
with the compressor running at full load – this
would indicate a rupture or crack.
Use only genuine Gardner Denver air
filter elements on Gardner Denver
compressor units. Genuine parts are
available through your authorized
Gardner Denver distributor.
Do not oil this element. Do not wash
in inflammable cleaning fluids. Do
not use solvents other than water. Im-
proper cleaning may damage the ele-
ment.
Never operate the unit without the ele-
ment. Never use elements that are
damaged, ruptured or wet. Never use
gaskets that won’t seal. Keep spare
elements and gaskets on hand to re-
duce downtime. Store elements in a
protected area free from damage, dirt
and moisture. Handle all parts with
care.
