SECTION 6
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 adequate and timely filter service is MOST
IMPORTANT. An improperly maintained air filter can cause a loss of compressor air delivery.
Filter Element - Clean every 50 to 150 operating hours depending on dust conditions.
Use only genuine Gardner Denver air filter elements on Gardner Denver
compressor units. Genuine parts are available through your authorized
Gardner Denver distributor.
To service:
1.
Remove the wingnut and pull out the filter element.
2.
Visually inspect the element. If cleaning is not necessary, reinstall the filter element. If the element
requires cleaning, follow steps 3, 4 and 5.
3.
Wash the element by soaking about 15 minutes in warm water with a mild non-sudsing detergent.
Rinse the element thoroughly with clean water; a hose may be used if the water pressure does not
exceed 40 psig (2.8 bar).
4.
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 end) of the element; replace the entire element if the gasket
is damaged. A spare element will keep down time to a minimum.
5.
Allow the element to air dry COMPLETELY. Do not expose the element to heat over 150° F (66° C).
Install the element in the filter body and fasten securely with the wing nut.
