Water Removal; Air/Fluid Separator; Air Filter - Quincy QSI-90 Instruction Manual

Water Removal

Water vapor may condense in the reservoir
and must be removed. The frequency
with which water must be removed is
determined by the ambient air conditions.
During hot and humid conditions, water
should be drained off the bottom of the
reservoir daily. In cold and dry conditions,
water may only need to be drained weekly.
To drain water from the reservoir, turn
the compressor off and let sit for at least

Air/Fluid Separator

The air/fl uid separator is a spin on, full fl ow
unit. Replacement requires spinning off
the cartridge and replacing it with a new
one.
The air/fl uid separator should be replaced
as indicated in the maintenance schedule
or as follows:

Air Filter

The standard QSI air fi lter is a single
stage, dry type element attached to the
inlet valve. The fi lter media is pleated and
will stop particles of 10 microns in size.
This element is replaceable and should
not be cleaned. Service intervals of the
air fi lter element depends on ambient
conditions and should be established by
checking regular intervals until a pattern
for servicing is found. Daily maintenance
of the fi lter 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 fi lter is
serviced, inspect the fi ltered air side of
the air cleaner canister and the suction
manifold for dirt. If dirt is found, determine
the cause and correct. Always make

5 minutes. Then open the drain valve.
Water is heavier than the compressor
fl uid and will collect at the bottom of the
reservoir. When the drain is fi rst opened
some compressor fl uid may come out
before the water starts to fl ow. Close
the valve when the water fl ow changes
to compressor fl uid. Make certain that
there is no pressure in the reservoir before
opening the drain valve. Water content in
the compressor fl uid in excess of 200 PPM
could cause bearing damage and airend
failure.

♦
4000 hours maximum or as indicated by
differential pressure indicator.
sure all gaskets, threaded connections,
fl ange connections, and hose connections
between the air fi lter and air compressor
are airtight. Dirty fi lters result in reduced
airfl ow and can distort the element and
allow dirt to bypass the fi lter element.
NOTICE!
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 voided if inadequate
filtration causes a failure.
