Gardner Denver Compressor EBH99G

Warning: The following readings are based on ambient temperature of 80° F (27° C) for air-cooled oil cooler and 80° F (27° C) inlet water on water-cooled oil cooler, with the system in good condition.

Compressor should be at operating temperature at the time of checks. One-half hour of loaded operation is usually sufficient to reach level-out operating temperatures.

Check for dirt accumulation on oil/aftercooler core faces and the cooling fan.

If cleaning is required, follow the steps below:

Was the cleaning operation successful?

This cleaning operation will keep the exterior cooling surfaces clean and ensure effective heat dissipation.

Operating conditions determine frequency of service.

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

Notice! Use only genuine Gardner Denver air filter elements on Gardner Denver compressor units.

Genuine parts are available through your authorized Gardner Denver distributor.

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.

Unit stopped and no air pressure in the oil reservoir

Gasket face of the filter body cleaned

New element gasket coated with clean lubricant used in the unit

New element screwed on the filter body and tightened by hand

Warning: Do not over tighten the element

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

Oil carryover through the service lines may be caused by a faulty oil separator, faulty minimum pressure valve, over-filling of the oil reservoir, oil that foams, oil return line malfunction or water condensate in the oil.

If oil carryover occurs, inspect the separator only after it is determined that the oil level is not too high, the oil is not foaming excessively,

the oil return line from the separator housing to the compressor cylinder is not clogged or pinched off, the check valve in the oil return line is functioning properly, and there is not water or an oil/water emulsion in the oil.

Oil carryover malfunctions of the oil separator are usually due to using elements too long, heavy dirt or varnish deposits caused by inadequate air filter service, use of improper oil or using oil too long for existing conditions.

A ruptured or collapsed separator element is usually due to heavy dirt or varnish buildup in the filtering material.

Excessive tilt angle of the unit will also hamper separation and cause oil carryover.

Oil separator element life cannot be predicted; it will vary greatly depending on the conditions of operation, the quality of the oil used and the maintenance of the oil and air filters.

The condition of the separator can be determined by pressure differential gauging or by inspection.
