Air Filter - Gardner Denver L Series Original User And Service Manual

Changing times for the fine oil separator
Operating conditions (e.g., coolant temperatures), the type of operation and the quality of the intake air
(e.g., dust content, ratio of gaseous foreign substances such as SO2 and solvent vapors) have a strong
influence on the filter lifespan (air filter, oil filter, fine separator).
In these cases the intervals between changes may be shorter.

8.6.6 Air Filter

Only perform checks and carry out work on the screw compressor when the unit is out of operation,
depressurized, and secured from being switched on again!
Never operate the screw compressor system without an air filter (even briefly removing it can cause
considerable damage to the machine)!

The compressor is equipped with two air filters. The air filter serves to filter the intake air. The condition of
the air filter must be checked through regular visual inspections.
As a standard, the air filter is provided with a visual in-take filter monitor, which indicates clogging of the
air filter cartridge.
When the red service field of the intake filter monitor is visible and remains clicked into position while the
screw compressor is out of operation, replace the air filter cartridge.
However, the air filter cartridge should be replaced per the Maintenance Schedule. Check air filter at least
once a week or, if required, daily for the accumulator of dust. When carrying out maintenance work, make
sure that no dirt gets to the clean air side of the air filter.
