Gardner Denver Screw Air Compressor ESM80

Clean the filter mat by brushing or washing.

Never install the filter mat in a wet or moist state!

c) Inlet filter to control cabinet (only VS 55-VS 75)

• Open the louvred grilles of the inlet filter (Fig. 27).

• Insert the new filter pad into the louvred grille.

Ensure that the smooth side (-A- Fig. 27) of the filter pad faces the air inlet side.

Changing intervals for air filter cartridge

The operating conditions (e.g. coolant temperatures), the operating modes and the quality of the intake air (e.g. content of dust, content of gaseous foreign matter such as SO2, solvent vapours, etc.) have a strong influence on the service life of the filters (air filters, oil filters, fine separators).

Where such conditions exist the filter element may require changing more frequently.

Change the air filter as follows:

• Pull snap latch outward and remove housing base.

• Detach air filter cartridge while slightly turning it.

• Carefully insert new air filter cartridge in the housing.

• Close air filter with housing base. The snap latches must click into position.;

Warning: Only change the oil when the screw compressor unit is out of operation, depressurized, and secured from being switched on again! Be careful when draining hot oil: Danger of scalding!

Important: Remove oil residues and other deposits from unit parts and from the coolers of compressors, which are exposed to hot compressed air, according to the operating instructions.

Note: Collect the waste oil, do not allow it to seep into the ground! Disposal in accordance with the regulations! Do not spill oil! Check for leakage!

With these compressors, the oil change intervals strongly depend on the degree of contamination of the circulating oil.

When changing the oil, the waste oil is to be drained completely, since used oil reduces the service life of the new oil fill considerably. Do not mix lubricating oils of different makes.

Switch the screw compressor unit off and ensure that it is depressurized, electrically isolate and locked off.

Slowly open the oil filler cap, to depressurize the screw compressor by releasing any residual pressure in the unit

Open the oil drain for the pressure reservoir and the oil cooler

Check the water circuit fittings

Check the hose for unsealed areas

Check the piping for unsealed areas
