Air/Fluid Separator Elements
Continuity Testing of Separator Elements
NOTICE!
Electrical continuity between all separator
element metal surfaces must be checked prior to
replacing any separator element. Do not install
if continuity is not present. Return the separator
element to your Quincy Distributor for
replacement.
Prior to installation, test the separator element as follows:
1) Locate a continuity test light or a volt-ohm-meter
(v-o-m) capable of reading 20 ohms.
2) Assure that battery has proper charge. Touch the
probe leads together to assure the light works or to
zero calibrate the meter.
3) Contact the grounding spring clip on the separator
element gasket with the ground probe of the test
indicator.
4) Touch the top cap of the separator element with the
other probe. The indicator light should illuminate
on the test or the v-o-m test must read no more than
20 ohms.
5) Touch the bottom cap of the separator element.
The indicator light should illuminate on the test or
the v-o-m test must read no more than 20 ohms.
6) Touch the outside wire mesh. The indicator light
should illuminate on the test or the v-o-m test must
read no more than 20 ohms.
7) Touch the inside wire mesh ( do not puncture the
element media). The indicator light should
illuminate on the test or the v-o-m test must read no
more than 20 ohms.
8) If the separator element fails any of the above test ,
return it to your Quincy Distributor for
replacement.
9) Make sure the compressor is bonded (wired) to an
earth ground to dissipate static electricity.
Air Filter
The standard QSB/T
™
air filter is a single stage, dry type
element attached to the inlet valve. The filter 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 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.
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.
A heavy-duty air filter is optional on all QSB/T ™ 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.
Control Line Filter
An automatic draining control line filter is used. Draining
occurs only when the compressor is in the unloaded
condition.
