Gardner Denver Screw Air Compressor EBEQEJ

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.

Is the air filter properly maintained?

An improperly maintained air filter can cause a loss of compressor air delivery.

Operating conditions determine frequency of service. If the “CHANGE SEPARATOR” message is displayed, the oil separator element requires changing.

Removal Of Oil Separator For Inspection Or Replacement:

1. Be certain unit is completely off and that no air pressure is in the oil reservoir.

2. Disconnect, tag and lockout power supply to the starter.

3. Remove screws holding the top plate to the separator housing. Lift the top plate from the separator housing.

4. Lift the separator from the separator housing.

5. Inspect and/or replace the separator as necessary. Be sure the o-ring is not damaged. Before installing (or reinstalling) any separator apply grease to the o-ring. Oil will be wiped off by the chamfer and the o-ring could be damaged.

6. Remove any gasket material adhering to top plate or separator housing, and install new gasket.

7. Lower the separator into the housing and center the separator on the chamfer. Press separator down into the housing. Do not use excessive force as separator damage can occur.
