Gardner Denver Air Compressor L75RS

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 substances such as SO2 and solvent vapors, etc.) have a strong influence on the service life of the filters (air filters, water 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.
