Air Filter
A heavy-duty air filter is standard on all
QGV 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.
To replace the air filter element:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Remove the cover from the end of the
air filter canister.
• Remove the old filter and replace with a
new one.
• Secure the cover after making certain
the element is seated correctly in the
canister.
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.
Air/Fluid Separator Element
The separator element is a one piece
construction that coalesces the fluid mist,
passing through the filtering media, into
droplets that fall to the bottom of the
separator element to be picked up by
a scavenging tube and returned to the
compressor. Use care when handling
the separator element to prevent it from
being damaged. Denting may destroy the
effectiveness of the filtering media and
result in excessive fluid carryover. Even
a very small hole punctured through the
element will result in a high fluid carryover.
Warning!
QGV-50 thru 100 horsepower: Do not
remove the staples from the separator
element. Their function is to prevent
an electrostatic buildup which could
spark a fire. Use genuine Quincy
replacement separators.
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.
