Air Filter; Control Line Air Filter - Quincy QSF Series Instruction Manual

Section V– Servicing

Air Filter

The standard air filter for the QSF stock version consists of an automotive style disposable element(s).
Removal and replacement is accomplished by unscrewing the wing nut and exchanging the element(s).
Tighten the wing nut snugly after making certain the element is seated correctly on its mounting base.
An optional two stage dry-type heavy-duty filter is available for the QSF stock version.
The heavy-duty air filter is supplied on standard QSF models. The heavy-duty air filter is a two stage, dry
type element. The first stage is cyclonic. That is, centrifugal airflow spins the larger dirt particles to the
outside walls of the filter canister. In the second stage, air passes through the filter element with an
efficiency of 99.9% as tested by SAE J7266 test code specifications. Removal and replacement of the
element is accomplished by unscrewing the wing nut and exchanging the element. Tighten the wing nut
snugly after making certain the element is seated correctly on its mounting base.
Service intervals of the air filter element depend on ambient conditions and should be established by
checking at 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 would be advisable to relocate the intake
air to an outside source.
Each time a 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 absolutely airtight.
Dirty filters result in reduced airflow and can distort such that dirt will bypass the filter element.
NOTE:
Intake filtration equipment supplied from the factory may not be adequate for extremely dirty
applications or some forms of dust or vapors. It is the customer's responsibility to provide
adequate filtration for those conditions. Warranty will be void if a failure is determined to be
caused by inadequate filtration.

Control Line Air Filter

An automatic draining control line filter is used. Draining occurs only when the compressor is in the
unloaded condition.
