General Description
Quincy QGV series compressors are
single stage, positive displacement, fluidflooded rotary screw compressors with
variable frequency drives. The drive motor
directly drives the male rotor through
a flexible drop out type coupling with
no step up or step down gearing. The
compressor airend contains two precisionmachined rotors, a male rotor with four
lobes in constant mesh with a female
rotor consisting of six flutes. The rotors
are housed in a cast iron cylinder with two
INLET PORT
parallel adjoining bores. The airend has
an inlet port at the power input end and
a discharge port at the opposite end. All
parts are machined to exacting tolerances.
QGV model compressors use positive
pressure in the reservoir to circulate the
compressor fluid through the system.
All compressor components are mounted
on a heavy-duty steel frame. Controls and
indicators are arranged on a control panel
and acoustical cabinets are available to
reduce sound levels.

Section II - Description
The Compression Cycle
The compression cycle of a rotary
compressor is a continuous process from
intake to discharge with no reciprocating
mechanisms starting and stopping as
found in reciprocating compressors.
As the rotors rotate, (male-clockwise as
viewed from the power input end) air is
drawn into the cylinder through the inlet
port located at the power input end. A
volume of air is trapped as the rotor lobes
pass the inlet cut off points in the cylinders.
Compression occurs as the male rotor
rolls into the female flute, progressively
reducing the space thereby raising the
pressure. Compression continues until
the lobe and flute pass the discharge port.
The compressed air is then discharged
into the air/fluid reservoir. There are four
complete compression cycles for each
complete rotation of the male rotor.
Air Flow
With the compressor operating, a partial
vacuum is produced at the compressor
inlet. Air entering via the compressor air
filter flows through the air inlet valve into
the rotor housing where it is compressed,
then discharged into the air/fluid reservoir.
Compressed air passes through the
complete system then through a minimum
pressure check valve to the service
connection.
Capacity Control System
The capacity control system on QGV
compressors is a start/stop control which
varies air delivery based on target pressure
(usage).
As the motor begins driving the
compressor rotors, air is drawn in,
compressed and discharged into the
air/fluid reservoir. When the air pressure
in the reservoir exceeds the set point,
the QGV variable speed drive begins
controlling the speed of the compressor.
The drive matches air delivery of the
compressor to air usage in the plant,
maintaining pressure at the target pressure
(± 1 psi).
If a reduction in usage is experienced,
the drive will slow to compensate for the
reduction. If the drive speed slows to 600
RPM (indicating that no air is needed), the
drive will shut down the compressor. The
compressor will restart automatically when
demand returns.
WARNING!
Never assume it is safe to work on a
compressor because it is not operating.
It may be in standby mode and could
restart at any time. Follow all safety
instructions in the “Preparing for
Maintenance or Service” section.
Quincy Compressor-QGV Series 7

Section II - Description
Cooling System
Fluid Coolers
Fluid coolers may use either air or water
as a cooling medium. The following
descriptions point out the major
differences between the two types of
coolers.
Air-cooled Fluid Coolers
The air-cooled fluid cooler and aftercooler
are of the finned aluminum tube, one
piece design. Ambient air is forced
through the fins by a motor driven fan,
cooling the fluid and air in the tubes. To
maintain proper compressor operation,
the ambient air temperature should
not exceed the temperatures listed in
Appendix B - Technical Data. The cooler
fins must be kept clean at all times. Fluid
leaving the reservoir passes through a
thermal mixing valve before traveling on
to the cooler. The purpose of the thermal
valve is to maintain a minimum fluid
discharge temperature at the compressor
of approximately 180°F.
Water-cooled Fluid Coolers
Water-cooled fluid coolers are of the shell
and tube design. Fluid passes through
the shell transferring its heat to the water
flowing through the tubes. Fluid leaving
the cooler does not pass through a thermal
mixing valve as in an air-cooled unit, but
goes directly to the fluid filter and the
compressor. Fluid discharge temperature
at the compressor is maintained by a water
temperature regulating valve located
in the discharge water line. The water
temperature regulating valve uses a probe
to sense fluid temperature and opens and
closes, governing water flow through the
cooler.
Aftercoolers
Aftercoolers reduce the amount of water
in the discharge air. They are used to
lower the temperature of the discharge
air thereby condensing water vapor from
the compressed air. This allows most of
the contained water to be trapped and
expelled from the unit, reducing water
related problems downstream.
Air-cooled aftercoolers are part of the aircooled fluid cooler. Cooling air from the
fan is blown through the aftercooler and
the fluid cooler.
Water-cooled aftercoolers are placed in
series with the fluid cooler. Incoming water
is first directed through the aftercooler and
then on to the fluid cooler.
A combination moisture separator and
water trap is provided for collecting and
expelling water to the customer’s drain.

Electrical System
Section II - Description
A diagram of the electrical system is
shown in the parts manual sent with the
compressor. A wiring diagram is also
included in the control panel on all Quincy
QGV compressors.
NOTICE!
Due to continuing product improvements
and updates, it is suggested that the
wiring diagram included in the control
panel be used when servicing the
electrical control.
Standard drive motors are open drip
proof 1800 RPM with a maximum ambient
temperature rating of 104°F. They are not
suitable for salt laden, corrosive, dirty, wet
or explosive environments.
The QGV series compressors utilize 460V
incoming power through a magnetic
starter. A transformer in the control panel
reduces this voltage to 120 VAC for various
electronic controls on the unit. These
controls include the pressure transducer,
high air temperature safety switch and
probe, solenoid valve and various indicator
lights.
Other incoming line voltages are available
as options. The compressor is provided
with a NEMA 1 enclosure. Optional panels
include NEMA 4.
Air-cooled models utilize a second
magnetic starter for protection of the fluid
cooler fan motor. This starter is connected
to the compressor starter through an
interlock which insures the fan motor is
operating with the compressor motor. If
the fan motor starter trips out for any
reason, the compressor unit will shut down.
DANGER!
High voltage could cause death or
serious injury. Disconnect all power
supplies before opening the electrical
enclosure or servicing.
Safety Sensors
Two high air temperature (HAT) sensors
are standard on QGV units. These sensors
protect the unit by sensing unusually high
temperatures and shutting the unit down.
One is located in the discharge line from
the compressor to the air/ fluid reservoir.
The second is located in the top of the
air/fluid reservoir. These sensors are set to
trip at approximately 225°F. The sensors
are nonadjustable.
WARNING!
Never remove, bypass or tamper
with the safety HAT switch. Failure
to provide this safety feature could
cause death or serious injury and
property damage. If the compressor
is shutting down due to high discharge
temperature, contact a qualified service
technician immediately.
Quincy Compressor-QGV Series 9

Section II - Description
Control Panel
QGV compressors are equipped with an
electronic control with a touch screen
control panel.
Once power is applied to the unit (after
going through several self test routines) the
touch screen (shown above) will indicate
the set point (target pressure), package
output pressure, discharge temperature,
operating mode, total hours of operation,
and the operating speed of the
compressor. A bar graph show the degree
of loading of the compressor. When the
bars match, the delivery pressure equals
the pressure set point.
Messages indicating service items that
need attention will appear on the touch
screen as they are tripped. The touch
screen menu also provides access to
various information and settings for the
compressor.
Only trained and knowledgeable service
personnel should alter the compressor
settings. Reference ‘Section IV - Operating
Procedures’ and ‘Section V - Servicing’ for
more information about QGV compressor
settings and menu options.

Receiving
Upon receipt, immediately inspect the
compressor for any visible damage that
may have occurred during shipment. If
visible damage is found, the delivering
carrier should make a notation on the
freight bill and the customer should
request a damage report. If the shipment
is accepted and damage is found later,
it is classified as concealed damage.
Concealed damage should be reported
to the delivering carrier within 15 days
of delivery. The delivering carrier must
prepare a damage report. Itemized
supporting papers are essential to filing a
claim.
Read the compressor nameplate to be
sure the compressor is the model and size
ordered and that optionally ordered items
are included.
Check the reservoir and pressure relief
valves to be sure they are adequate for the
pressure at which you intend to operate.
Moving the Unit to the Installation Site
Forklift slots are provided in one side and
one end of the main frame. Use of chains
and slings should be limited to the main
frame. Do not attempt to lift the unit by
attaching to any components. Optional
lifting eyes are available.
CAUTION!
Improper lifting may result in component,
system damage or personal injury.
Follow good shop practices and safety
procedures when moving the unit.
WARNING!
Removal or painting over safety labels
will result in uninformed conditions.
This could result in personal injury or
property damage. Warning signs and
labels shall be provided with enough
light to read, conspicuously located
and maintained for legibility. Do
not remove any warning, caution or
instructional material attached.

Location
Section III - Installation
Locate the compressor on a level surface
in a clean, well-lit and well-ventilated
area. Allow sufficient space (four feet
of clearance on all sides and top of
the compressor) for safe and proper
daily inspection and maintenance. The
entire length of the frame base must be
supported. Shim where necessary but do
not use wood.
Ambient temperature should not exceed
110°F. High ambient temperatures may
result in a high air temperature shutdown.
All models are intended for indoor
installation; however, it is possible, with
certain modifications, to accommodate
some outdoor locations. Cabinet models
are water-resistant but not water tight.
Sheltering from rain, snow and freezing
temperatures is mandatory.
WARNING!
Do not operate in temperatures below
32°F or above the limits outlined in
Appendix B - Technical Data.
Do not locate the unit where the hot
exhaust air from other compressors or heat
generating equipment may be
drawn into the unit. Never restrict the
flow of exhaust air from the fluid cooler
or cooling fan. Heated exhaust air
must be exhausted outside to prevent
high temperature conditions in the
compressor room. If the room is not
properly ventilated, compressor operating
temperatures will increase and cause a
high temperature shutdown.
Clean air is essential for your Quincy
QGV compressor. Always select a source
providing the cleanest air possible. When
an outside air source is used, keep all
piping as short and direct as possible. Use
vibration isolators and support all piping
correctly. Piping size should be at least
as large as the inlet valve opening and
increased several sizes for extremely long
piping runs. The piping must be leak free
and clean after fabrication.
In high humidity areas, avoid placing
the compressor in a basement or other
damp locations. Control the compressor
temperatures and monitor compressor fluid
for signs of water contamination. Fluid and
filter changes may need to be increased in
high humidity areas. Increased operating
temperatures may be required.
CAUTION!
Removal or modification of sound
insulation could result in dangerously
high sound levels.
Quincy QGV compressors are essentially
vibration free, however, some customers
may choose to bolt the unit to the floor
to prevent the accidental breakage of
piping or electrical connections as a result
of being bumped. Use only lag bolts to
secure the unit. Do not pull the bolts
down tight. Overtightening the lag bolts
may place the frame in a twist or bind
causing breakage of fluid coolers, piping
and reservoirs.
WARNING!
CAUTION!
Under no circumstances should a

atmosphere, nor should toxic, volatile
or corrosive agents be stored near the
compressor.
Page 20
Section III - Installation
Piping Connections
Never join pipes or fittings by soldering.
Lead-tin solders have low strength, a
low creep limit, and may, depending on
the alloy, start melting at 360°F. Silver
soldering and hard soldering are forms of
brazing and should not be confused with
lead-tin soldering. Never use plastic, PVC,
ABS pipe or rubber hose in a compressed
air system.
Piping Fit-up
Care must be taken to avoid assembling
the piping in a strain with the compressor.
Piping should line up without having
to be sprung or twisted into position.
Adequate expansion loops or bends
should be installed to prevent undue
stress at the compressor resulting from the
changes between hot and cold conditions.
Pipe supports should be mounted
independently of the compressor and
anchored, as necessary, to limit vibration
and prevent expansion strains. Piping
should never be of smaller size than the
connection on the compressor unit.
Relief Valves
Pressure relief valves are
sized to protect the system.
Never change the pressure
setting or tamper with
the valve. Only the relief
valve manufacturer or an
approved representative
is qualified to make such a
change.
DANGER!
Relief valves are installed to protect
system integrity in accordance with
ANSI/ASME B19 safety standards.
Failure to provide properly sized relief
valves will result in death or serious
injury.
Relief valves must be placed ahead of any
potential blockage point. That includes,
but is not limited to, such components
as shutoff valves, heat exchangers and
discharge silencers. Ideally, the relief
valve should be threaded directly into the
pressure point it is sensing (not connected
with tubing or pipe) and pointed away
from personnel.
CAUTION!
ASME coded pressure vessels must
not be modified, welded, repaired,
reworked or subjected to operating
conditions outside the nameplate
ratings. Such actions will negate code
status, affect insurance status and
may cause death, serious injury and
property damage.

Electrical
Section III - Installation
Before installation, the electrical supply
should be checked for adequate wire
size and capacity. During installation,
a suitable fused disconnect switch with
semiconductor fuses (AJT or LPJ type) or
circuit breaker should be provided. Any
unreasonable voltage unbalance (5%)
between the legs must be eliminated
and any low voltage corrected to prevent
excessive current draw. The installation,
electric motor, wiring and all electrical
controls must be in accordance with
National Electric Code, and all state
and local codes. A qualified electrician
should perform all electrical work. Air
compressors must be grounded in
accordance with applicable codes. See
control panel for the proper wiring
diagram.
Quincy Compressor would like to
emphasize the importance of providing
adequate grounding for air compressors.
The common practice of grounding units
to building structural steel may not actually
provide adequate grounding protection, as
paint and corrosion buildup may exist.
CAUTION!
NEMA el ect ric al enclosures a nd
components must be appropriate to
the area in which they are installed.
Pneumatic Circuit Breakers or Velocity Fuses
The Occupational Safety and Health Act,
Section 1926.303 Paragraph 7 published
in Code of Federal Regulations 29 CFR
1920.1 (revised 07/01/1982), states “all
hoses exceeding 1/2” inside diameter
shall have a safety device at the source of
supply or branch line to reduce pressure in
case of a hose failure.” These pneumatic
safety devices are designed to prevent
hoses from whipping, which could result in
a serious or fatal accident.
Guards
All mechanical action or motion is
hazardous in varying degrees and needs to
be guarded. Guarding shall comply with
OSHA Safety and Health Standards 29 CFR
1910.219 in OSHA manual 2206 (revised
11/07/1978) and any state or local codes.
Manual Vent and Shutoff Valve
Install a manual valve to vent the
compressor and the compressor discharge
line to atmosphere. If the air receiver tank
services a single compressor, the manual
valve can be installed in the receiver.
When a manual shutoff valve (block valve)
is used, a manual valve should be installed
upstream from the valve, and a pressure
relief valve installed upstream from the
manual vent valve. These valves are
to be designed and installed to permit
maintenance to be performed in a safe
manner. Never substitute a check valve for
a manual shutoff valve (block valve) if the
purpose is to isolate the compressor from a
system for servicing.
Quincy Compressor-QGV Series 15

Section III - Installation
Water and Sewer Facilities at the Installation Site (water-cooled models)
Clean, soft and/or treated water is required
to ensure the efficient, long service life of
the water-cooled heat exchangers.
It is strongly recommended that a
reputable, local water treatment company
be engaged prior to start-up to establish
the corrosion, scale forming and fouling
tendency of the cooling water and remedy
the situation if a problem exists.
NOTICE!
Failure to develop a water treatment
pl a n may r esu l t in i n cre a s e d
maintenance and operating expense,
reduced equipment life and emergency
shutdown.
Make sure the water supply is connected
and open. Piping supplied by the user
should be at least equal to the connections
provided on the compressor. Sewer
facilities should be readily accessible
to the installation site and meet all the
requirements of local sewer codes, plus
those of the compressor. Make sure
water inlet and discharge connections are
correct.
NOTICE!
A water temperature regulating valve is
located in the discharge water line.

Section III - Installation
Compressor Rotation
Compressor rotation is controlled by the
variable speed drive (drive motor only).
Correct connection of the drive motor (to
the drive) is verified at the factory. If the
drive motor is disconnected for any reason,
follow the wiring diagram supplied with the
drive motor when reconnecting the motor
to the drive to ensure proper rotation.
WARNING!
Ope rating the compres sor with
incorrect rotation will result in extreme
damage to the compressor and warranty
coverage will be voided.
Fan Rotation (air-cooled only)
Check the fan rotation prior to start-up.
Fan airflow should be outward, that is,
pushing the air through the coolers.

maximum safety of service personnel:
• Disconnect and lockout the main power
switch and hang a sign at the switch of
the unit being serviced.
• Close shutoff valve (block valve)
between receiver and plant air system
to prevent any backup of air flow
into the area to be serviced. NEVER
depend upon a check valve to isolate
the system.
• Open the manual vent valve and wait
for the pressure in the system to be
completely relieved before starting
service. DO NOT close the manual
vent valve at any time while servicing.
WARNING!
Relieve compressor and system air
pressure by opening the appropriate
manual relief valve prior to servicing.
Failure to relieve all system pressure
could result in death or serious injury
and property damage.
• (Water-cooled units) - Shut off water
and depressurize system.
WARNING!
Never assume the compressor is ready
for maintenance or service because it is
stopped. The automatic start feature
may start the compressor at any time.
Death or serious injury could result.

Safety
Safety procedures while servicing the
compressor are important to both the
service personnel and to those who may
be around the compressor and the system
it serves. Listed below are some, but not
all, procedures that should be followed:
• Wait for the unit to cool before
starting service. Temperatures may
exceed 180°F when the compressor is
operating.
• Clean up fluid spills immediately to
prevent slipping.
• Loosen, but do not remove, flange or
component bolts. Carefully pry apart
to be sure there is no residual pressure
before removing bolts.
• Never use a flammable solvent such as
gasoline or kerosene for cleaning air
filters or compressor parts.
• Safety solvents are available and should
be used in accordance with their
instructions.
NOTICE!
Maintenance or service should be
performed by trained and qualified
service technicians only.
CAUTION!
Unusual noise or vibration indicates
a problem. Do not operate the
compressor until the source has been
identified and corrected.
Water Removal
Water vapor may condense in the reservoir
and must be removed. Water is heavier
than the compressor fluid and will collect
at the bottom of the reservoir.
The frequency with which the 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.
WARNING!
Water content in the compressor fluid in
excess of 200 PPM could cause bearing
damage and/or airend failure.
To drain water from the reservoir:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Allow compressor to sit idle for at least
5 minutes.
• Open the drain valve.
• Close the valve when the water
flow changes to compressor fluid.
(When the drain is first opened some
compressor fluid may come out before
the water starts to flow.)
• Since this water will contain some
compressor fluid, dispose of the water
in accordance with Local, State, and
Federal environmental regulations.

Section V - Servicing
Water Temperature Regulating Valve (75
& 100 hp, water-cooled units only)
The water
temperature
regulating valve
senses fluid
temperature and
opens or closes,
regulating water flow
from the unit. It is
factory set to maintain
180°F discharge
temperature.
Due to variations
of incoming water temperatures and/or
pressures at each location, check valve
adjustment during start-up to maintain
180°F discharge temperature.
• To increase fluid temperature: turn the
adjustment screw clockwise to decrease
water flow.
• To decrease fluid temperature: turn the
adjustment screw counterclockwise to
increase water flow.
Water-cooled Heat Exchangers
Most water-cooled heat exchanger
problems result from underestimating the
importance of water treatment and heat
exchanger maintenance. Cleaning the
heat exchanger tubes on a regular basis
and providing a clean, soft and/or treated
water supply will ensure the efficient, long
service life of the heat exchangers.
Impurities in the cooling water supply
can impact the service life of the heat
exchanger. It is strongly recommended
that a reputable, local water treatment
company be engaged prior to start-up to
establish the corrosion, scale forming and
fouling tendency of the cooling water and
remedy the situation if a problem does
exist.
NOTICE!
Failure to develop a water treatment
pl a n may r esu l t in i n cre a s e d
maintenance and operating expense,
reduced equipment life and emergency
shutdown.
Water treatment may involve filtration
(screening) to remove debris, sand and/or
silt in the water supply or, in more severe
cases, chemical treatment methods may
be necessary to inhibit corrosion and/or
remove suspended solids to reduce the
water’s tendency to form scale deposits or
prevent growth of microorganisms.
The normal maintenance program for
the unit should include periodic cleaning
of the tube side (water side) of the heat
exchanger to remove deposits that
enhance fouling and corrosion.
NOTICE!
The user is responsible for ensuring
adequate water quality and keeping the
heat exchanger clean. Heat exchanger
failure caused by plugging or corrosion
is not covered by warranty.

Compressor Fluid
The interval for changing the compressor
fluid depends on the type of fluid used and
the operating conditions of the unit. See
Section VI - Compressor Fluids for more
specific information concerning fluid life of
specific fluids.
Fluid change instructions:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Slowly unscrew the plugs at the fluid fill
and discharge port.
Fluid Filter
• Attach a pipe to the drain valve, open
the drain valve and allow all the fluid
to drain from the unit. In order for all
fluid to be removed, fluid should be at
running temperature (between 140°F
and 175°F).
• Dispose of the fluid in accordance with
Local, State, and Federal environmental
regulations.
• Remove the pipe, close the draincock
and reinstall the plug.
• Fill the compressor with the appropriate
amount of new fluid through the fluid
inlet port.
• Check the fluid level at the sightglass.
• Replace the o-ring on the fluid filler cap
and reinstall.
The fluid filter is a
spin on, full flow unit.
Replacement of the filter
requires spinning off the
cartridge and replacing
it with a new one.
The initial filter change
should occur after the
first 500 hours of operation. During normal
service, the filter cartridge should be
replaced under the following conditions,
whichever occurs first:
• every 1,000 hours
• every fluid change
Replacing the fluid filter:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Using a suitable band spanner, unscrew
and remove the fluid filter.
• Lubricate the new filter gasket and
install the filter.
Notice!
Use genuine Quincy replacement
filters only.
• Tighten using the band spanner.
• Dispose of the used fluid filter cartridge
in accordance with Local, State, and
Federal environmental regulations.

Fluid Level
Section V - Servicing
The correct fluid level is important for
the reliability of the compressor. The
fluid level is monitored by a sightglass
while the compressor is in operation. The
fluid level should be checked daily and
should be in the middle of the sightglass
(between ‘minimum’ & ‘maximum’) when
the compressor is running loaded. If a low
fluid level is observed, add enough fluid
to bring the fluid back to the proper level.
DO NOT OVER FILL. The correct fluid
capacity of QGV compressors is indicated
in the parts book supplied with the unit.
CAUTION!
To avoid damage to the compressor,
it is very important that the same type
of fluid be used when topping off the
fluid level in the compressor. Never
mix different types of fluid.
To top off the fluid level (add fluid):
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Wait one minute and check the fluid
level.
• Unscrew the fluid fill plug.
CAUTION!
Hot fluid under pressure could cause
death or serious injury. Do not remove
the fluid fill plug and attempt to
add fluid to the reservoir while the
compressor is in operation or when the
system is under pressure.
• Add the required amount of fluid
through the fluid fill opening.
• Reinstall the fluid fill plug.
• Restart the compressor and recheck the
fluid level.

Fluid Scavenging System
Fluid from inside the separator element
is returned to the inlet valve or airend by
a scavenger tube positioned inside the
separator element, through an orifice and
tube connected to the compressor. Failure
to keep the orifice clean will result in
excessive fluid carryover. Cleaning of the
orifice should be performed as follows:
• When no fluid
is seen moving
through the
scavenge line
sight glass.
Fluid Cooler/Aftercooler (air-cooled)
The exterior of the fluid cooler/aftercooler
should be cleaned periodically to ensure
sufficient cooling capability. Dirty fins
in the cooler degrade the ability for the
cooler to work properly.
To clean the cooler fins:
• When excessive fluid carryover is
detected.
• Every fluid change.
• Once per year.
NOTICE!
Do not ream the orifice or change the
orifice size. Do not install the orifice
reversed.
• Switch the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Clean the cooler fins using compressed
air.
Fluid Tubing
Flareless tubing is used in the fluid piping
to eliminate pipe joints and provide a
cleaner appearance.
Replacement tubing and fittings are
available; however, special installation
procedures must be followed. Your
authorized distributor has the necessary
instructions and experience to perform
these repairs.
Failure to install flareless tubing or
fittings correctly may result in the
tubing coming apart under pressure.
Serious injury and property damage
may result.

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.
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
Electrical contin uity 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.

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 has a gasket
on each side of the flange, repeat
steps 3 through 7.
9) If the separator element fails any
of the above test , return it to your
Quincy Distributor for replacement.
10) Make sure the compressor is
bonded (wired) to an earth ground to
dissipate static electricity.
QGV-150/200 Separator Installation
The 150 and 200 horsepower models
utilize an inside/out flow requiring the
separator seal to be located on the inlet
to the separator. The sealing surface is
located inside the pressure vessel and
is coated to prevent corrosion. Remove
any loose material prior to separator
installation.
After the continuity verification procedure
is complete install the separator as follows:
1. Lubricate the separator o-ring with
compressor fluid and place separator
inside the reservoir with o-ring end
facing down, centered inside studs.
2. Place the square separator
compression plate over the 4 studs.
3. Install the (4) Nylok nuts on studs and
tighten as follows:
Turn nuts down until they’re touching
the compression plate. Do not

Shaft Seal
Compressor shaft seals are wear
items that may eventually have to be
replaced. Special tools and a complete
understanding of the installation procedure
are required for a successful seal
replacement. Ask your Quincy distributor
for complete illustrated instructions
(available as a Service Alert) at the time
you order the seal and special tools, if you
decide to replace the seal yourself. If your
distributor does not have a copy of these
instructions, they can be ordered from
Quincy Compressor at no charge.
QGV compressors incorporate a fluid
scavenge system to complement the use
of a triple lip seal assembly. Any complaint
of shaft seal leakage requires that the
scavenge system be inspected for proper
operation prior to the replacement of the
shaft seal. Proper inspection consists of
the following:
• Assure that the scavenge line itself is
not plugged.
• Inspect the performance of the
scavenge line check valve by removing
the fitting located at the bottom of
the motor adapter. Remove the check
ball and inspect for wear. If the check
valve is stuck open, fluid can backflush
from the airend into the seal cavity and
appear as a leak. If the check valve
is stuck closed the seal cavity will not
scavenge. Replace if necessary.
• Remove the coupling guards and
coupling halves
• Insert two of the seal adapter retaining
bolts into the seal adapter jack holes
and turn clockwise (pushing the seal
adapter away from the suction housing).
• After the seal adapter outer o-ring has
cleared the seal adapter bore, remove
the adapter for inspection.
• Disassemble the seal adapter as
follows:
a. With the face of the seal adapter up,
insert two small, flat screwdrivers
under the outer lip of the fluid slinger
and pop the slinger from the seal
adapter bore.
b. Using a brass drift, tap the shaft seal
assembly from the seal bore.
c. Inspect both seal lips for excessive
wear, lip flaws or damage.
d. Inspect the outer o-ring on the fluid
slinger for cuts or nicks.
e. Inspect the outer o-ring on the seal
adapter for cuts and nicks.
f. Slide the wear sleeve removal tool
over the end of the shaft and allow
the jaws of the tool to snap on the
backside of the wear sleeve. Tighten
the outer shell of the tool down over
the inner jaws.
g. Using a ratchet and socket, turn the
puller jack screw clockwise in against
the end of the compressor shaft to
remove the seal wear sleeve.
• Remove the drive coupling hub and key
from the compressor shaft.
• Remove the drive motor.
• Remove the four bolts securing the seal
adapter to the suction housing.
Do Not use an impact wrench with this
tool.

Preparation for New Seal Installation
• Inspect the compressor shaft for burrs
or deep scratches at the wear sleeve
area. Using a 100-grit emery cloth,
lightly sand horizontally any rust or
Loctite™ on the shaft. Using a fine file
or emery cloth, deburr the key area of
the rotor shaft. Cover the keyway with
masking tape to prevent damage to the
new seal during installation.
• Clean the seal adapter with fast drying
solvent. Assure that the scavenge drain
in the seal adapter is clean and open.
Place the outer face of the seal adapter
on a flat, hard surface.
• Remove the new triple lip seal from the
package and inspect for damage or
imperfections on the seal lips.
• Apply a thin coat of Loctite™ 290 to
the outer steel case of the seal and
position the seal in the seal adapter
bore.
• Insert the proper seal driver over the
seal. Insert the proper wear sleeve
driver in the seal driver and tap the new
seal into the bore with a medium sized
hammer.
Seal Installation
• Apply a thin coat of compressor fluid to
the outer face of the wear sleeve and
seal lip.
• Slide the proper seal installation sleeve
against the wear sleeve with the taper
toward the end of the rotor shaft.
• Install a new o-ring on the seal adapter
and lubricate with compressor fluid.
• Install a new o-ring around the
scavenge port (use petroleum jelly to
hold the o-ring on the seal adapter face
during installation).
• Carefully slide the seal adapter with the
new seal installed over the end of the
rotor shaft and up against the adapter
bore.
• Using care not to damage the o-ring,
evenly draw the adapter into the bore,
install the four retaining bolts and
tighten to the specified torque.
• Remove the installation sleeve.
• Apply a thin film of compressor fluid to
the o-ring and seal lip of the outer fluid
slinger.
• Preheat the wear sleeve (in a small
oven) to 350°F. Do not preheat in
warm oil.
• Apply a thin film of Loctite™ to the
inner diameter of the wear sleeve and
immediately install on the compressor
shaft using the proper wear sleeve
driver. Drive the wear sleeve on the
shaft until the driver bottoms on the
shaft shoulder.

Fluid Specifications
The functions of the compressor fluid are:
• to lubricate the bearings and rotors.
• to remove heat from the air as it is
being compressed thus lowering the
compressed air discharge temperature.
• to seal the rotor clearances.
We recommend that all Quincy rotary
screw compressors be filled with one of the
following synthetic fluids:
QuinSyn-Plus - Standard fill. Synthetic
hydrocarbon/ester blend.
QuinSyn-XP - Standard fill for high
pressure applications.
Synthetic polyolester.
QuinSyn-PG - Synthetic polyalklene
glycol/ester blend.
QuinSyn-F - Special fluid blend for food

recommendations will adversely affect
your warranty.
44 Quincy Compressor-QGV Series
Page 51
Section VI - Compressor Fluids
Lubrication
QGV models use pressure differential
to circulate the fluid. Positive pressure
maintained in the reservoir forces fluid
throughout the machine. Fluid is circulated
through the cooler, fluid filter, and into the
compressor.
In the compressor, fluid is diverted through
internal passages to ensure positive
lubrication of the bearings and shaft seal.
The remainder of the fluid is injected at the
beginning stage of the compression cycle
to seal clearances and to cool and lubricate
the rotors.
Each Quincy compressor is filled at
the factory with the correct amount
of one of the synthetic fluid listed in
the Fluid Specifications. Mineral oil
can be requested and used in specific
applications. The use of other brands or
types of fluid may reduce the design life
of the compressor or cause problems with
filtration or carryover. Consult the Quincy
Service Department before changing
brands of fluid.
Fluid Sample Valve
QGV models are equipped with a fluid
sample valve located at the discharge of
the fluid filter.
Figure 6-1. Fluid Sample Valve
Fluid samples should be taken from the
sample valve while the compressor is
running at normal operating temperature
(see Sampling Procedures - page 47).
Quincy Compressor-QGV Series 45
Page 52
Section VI - Compressor Fluids
Factors Affecting Fluid Life
To protect your investment, check for the
following, which can affect the long life of
QuinSyn:
1) High operating temperatures
2) Contaminants:
a. Other fluids
b. Strong Oxidizers such as:
• acids
• sulfur
• chlorine
• burnt fuel i.e. exhaust from: forklifts,
boilers, jet aircraft
• nitrogen oxides
• ozone
• welding fumes
• plastic molding fumes
c. Ammonia
d. Solvent fumes:
• chlorinated degreasers
• ink solvents
e. Airborne dust and particles
f. Paper digester fumes
Locate your compressor in the coolest
area possible. For every 18°F above
195°F, the operating life of any fluid
is reduced to about half that at 195°F.
Some mineral oils begin to form varnish at
temperatures above 200°F. QuinSyn fluids
are more forgiving than mineral oil at high
temperatures. QuinSyn-XP is designed to
operate at sustained temperatures above
200°F. The life of other QuinSyn fluids will
be shortened at high temperatures.
Air intake should provide contaminantfree, cool air. A Quincy heavy-duty intake
filter will reduce the risk of abrasion and
increased wear. An air filter does not
eliminate reactive gases. Inspect your filter
monthly and replace as required.
Fluid Analysis Program - General
Quincy’s fluid analysis program is offered
to all customers using QuinSyn fluids
in Quincy Compressor Rotary Screw
Compressors. This service provides
optimum drain intervals for compressors
operating on QuinSyn fluids. Monitoring of
the total acid number (TAN), barium level
and/or viscosity throughout the life of the
fluid provides maximum protection to your
machine, while best utilizing the extended
life features of QuinSyn.
The fluid analysis provides historical
information, detailing items such as
hours on the fluid, viscosity and total acid
number (TAN). Should results appear
unusual or suspicious, a detailed analysis
can pinpoint specific contaminants.
A detailed report is furnished to you,
your Quincy Distributor and the Quincy
Compressor factory upon completion of
the fluid analysis.
Although QuinSyn fluids are rated by hours
of life expectancy under normal operating
conditions, it is recommended that fluid
samples be taken every 500 to 2000 hours
and sent to Quincy Compressor Fluid
Analysis until a history of performance
in a specific compressor application is
established. Once the appropriate drain
interval is established, the frequency of
the fluid analysis can be reduced unless
operating conditions change.
The depletion of antioxidants, change of
viscosity, barium and acid levels all occur
with time. It is extremely important to
change QuinSyn before the antioxidants
are completely depleted. If the fluid is left
in the compressor beyond its useful life,
removing all of the spent fluid is difficult.
The oxidation products remaining can
considerably shorten the life of the new fill
of QuinSyn fluid.
NOTICE!
All Quincy Compressor extended
airend warranty programs require
that fluid samples be sent to Quincy
Compressor Fluid Analysis a minimum
of every 2,000 hours.

Section VI - Compressor Fluids
QuinSyn-Plus
QuinSyn-Plus is the factory fill for all rotary
screw compressors and vacuum pumps
manufactured at the Bay Minette facility
unless a different fluid is requested.
QuinSyn-Plus is a synthetic hydrocarbon/
ester, ISO 46 viscosity fluid with an
8,000 hour life under normal operating
conditions (exact fluid life is determined by
the fluid analysis program).
QuinSyn-Plus is totally compatible with
QuinSyn. Machines currently running with
QuinSyn fluid can be topped off with
QuinSyn-Plus with no adverse effects.
Some advantages of QuinSyn-Plus are:
• Superior demulsability (ability to
separate from water)
• Less susceptible to varnish
• Extremely low volatility
• Excellent corrosion protection
• Outstanding low temperature
properties
• Exceptional thermal stability
• Excellent oxidative stability
• Better gas-fluid separation

Applications
QuinSyn-Plus is suited for use in rotary
screw air compressors operating in
harsh service conditions where the fluid
is exposed to higher temperatures for
extended periods of time. Fluid thermostat
temperature settings can be elevated to
assist in reducing water content in the
fluid in high humidity applications. Please
consult Quincy Service Department for any
thermostat changes.
Disposal
QuinSyn-Plus is considered nonhazardous
waste. Disposal of this fluid should be
done in accordance with Local, State, and
Federal regulations. Should condensate
need to be treated, Quincy’s QIOW fluid/
water separators are required.
Fluid Analysis Program
QuinSyn-Plus fluid is included in Quincy’s
fluid analysis program.

QuinSyn-XP
Section VI - Compressor Fluids
QuinSyn-XP is the factory fill for high
pressure units (units operating above
150 psig full flow). QuinSyn-XP is totally
compatible with QuinSyn-HP 68 (the fluids
can be mixed together with absolutely no
problems). Aftermarket orders for QuinSynHP 68 will be filled with QuinSyn-XP.
QuinSyn-XP is a custom blended
polyolester (POE) fluid ideally suited for
rotary screw air compressors. QuinSyn-XP
is an ISO 68 viscosity fluid with a 12,000
hour life at 100 & 125 psig full flow under
normal operating conditions and 8,000
hours as a high pressure fluid (exact fluid
life is determined by the fluid sampling
program).

Applications
QuinSyn-XP is designed for applications
where the fluid is exposed to elevated
temperatures for extended periods of time.
Fluid thermostat temperature settings
can be elevated to assist in reducing
water content in the fluid in high humidity
applications. Consult Quincy’s Service
Department before making thermostat
changes.
Disposal
QuinSyn-XP is considered nonhazardous
waste. Disposal of this fluid should be
done in accordance with Local, State, and
Federal regulations. Should condensate
need to be treated, Quincy’s QIOW fluid/
water separators are required.
Fluid Analysis Program
QuinSyn-XP will be analyzed similar to
QuinSyn although the primary concern is
the total acid number (TAN). Supplemental
“on site” TAN kits will be applicable to this
fluid as well as QuinSyn-PG.

Applications
QuinSyn-PG is best suited for applications
where high humidity exists and the
machine cannot be shut down to drain
water from the reservoir.
Disposal
QuinSyn-PG is considered nonhazardous
waste. Disposal of this fluid should be
done in accordance with Local, State,
and Federal regulations. Separation of
this fluid from condensate will require
those separators designed to handle
fluid emulsions. The QIOW fluid/water
separator is suitable for separation of fluid
emulsions such as QuinSyn-PG. Please
contact Quincy’s Service Department for
more details.
Fluid Analysis Program
The fluid sampling for QuinSyn-PG has
been extended to 2,000 hours because of
the superior quality and forgiving nature of
this fluid.
Primary concerns with this fluid are the
total acid number (TAN) and barium levels.
QuinSyn-PG will not be condemned on
water percentage nor antioxidants but will
be condemned on low barium and high
TAN values. The barium in the fluid acts as
a corrosion inhibitor, therefore low limits
have been set for this additive (see fluid
parameters for limits).

QuinSyn-F
Section VI - Compressor Fluids
QuinSyn-F is Quincy’s food grade fluid,
suitable in applications where there may
be incidental food contact. Compliant with
FDA 21 CFR 178.3570 (Lubricants With
Incidental Food Contact), QuinSyn-F is
authorized by the USDA with an H-1 rating
for use in federally inspected meat and
poultry plants. Since the fluid is viewed as
a possible indirect food additive, the limit
for food contact is 10 PPM. Near white in
color and low in volatility, QuinSyn-F is
ideal for clean service.
Fluid Life
QuinSyn-F provides an expected life
of 4,000 hours under normal operating
conditions.
Disposal
QuinSyn products are considered
nonhazardous under the OSHA Hazard
Communication Standard 21 CFR
