Air Filter
from Cat Dragline Marion QGB Series (20-60 HP) Belt Drive Air Compressors Operation & Maintenance Manual
Air Filter
The standard QGB™ air filter is a single stage, dry type element attached to the inlet valve. The filter media is pleated and will stop particles of 0 microns in size. This element is replaceable and should not be cleaned. Service intervals of the air filter element depends on ambient conditions and should be established by checking regular intervals until a pattern for servicing is found. Daily maintenance of the filter element is not uncommon in dirty conditions. If dirty conditions exist, it is advisable to relocate the intake air to an outside source. Each time the filter is serviced, inspect the filtered air side of the air cleaner canister and the suction manifold for dirt. If dirt is found, determine the cause and correct. Always make sure all gaskets, threaded connections, flange connections, and hose connections between the air filter and air compressor are airtight. Dirty filters result in reduced airflow and can distort the element and allow dirt to bypass the filter element.
