Gardner Denver Screw Air Compressor EBEQDH

Warning: Use only genuine Gardner Denver air filter elements on Gardner Denver compressor units.

Caution: Never operate the unit without the element. Never use elements that are damaged, ruptured or wet. Never use gaskets that won't seal.

Does the filter element require cleaning?

If cleaning is not necessary, reinstall the filter element.

If the element requires cleaning, follow the next steps.

Wash the element by soaking about 15 minutes in warm water with a mild non-sudsing detergent.

Enter the water pressure used for rinsing the element

Warning: The following readings are based on ambient temperature of 80 F (27 C) with the system in good condition. The compressor should be at operating temperature at the time of the checks. One–half hour of loaded operation is usually sufficient to reach level–out operating temperatures.

Air and Oil Discharge Temperature – Read at the gauge on the instrument panel or check with a thermometer at the discharge housing.

Compressor Oil Inlet Temperature – Install a tee at the oil filter outlet and check with a thermometer.

Oil Inlet Pressure – Check at the fitting in the line near the compressor oil inlet. With air receiver pressure at 100 psi (6.9 Bars), oil inlet pressure should be 65–75 psig (4.5 to 5.2 Bars).

Oil Cooler Oil Pressure Differential (Air–Cooled Radiator) – Check differential across the oil system by measuring oil inlet pressure as described above.

Oil Cooler Temperature Differential (Air–Cooled Radiator) – The oil temperature differential depends on the temperature of the air at the oil cooler fan and cleanliness of the core faces. As ambient temperatures and core restrictions increase, the oil cooler outlet temperature will increase.

The oil inlet temperature is approximately the same as the air discharge temperature – see the gauge on the instrument panel.

The outlet oil temperature may be checked by installing a tee at the oil filter outlet.

Operating conditions determine frequency of service.

Is the 'CHANGE AIR FILTER' message displayed?

If the 'CHANGE AIR FILTER' message is displayed, air filter requires servicing or changing.

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.
