Safety Precautions
Read this manual and follow all instructions
prior to installing or operating the
compressor.
Listed below are some, but not all, safety
precautions that must be observed with
compressors and compressed air systems.
WARNING!
Failure to follow any of these precautions
may result in severe personal injury,
death , propert y damage and/or
compressor damage.
• Air from this compressor will cause
severe injury or death if used for
breathing or food processing. Air
used for these processes must
meet OSHA 29 CFR 1910.134 or
FDA21XDE178.3570 regulations.
• Disconnect and lockout all power
supplies to the compressor plus any
remote controllers prior to servicing the
unit.
• Never assume it is safe to work on the
compressor because it is not operating.
Many installations have automatic start/
stop controls and the compressor may
start at any time.
• A properly sized pressure relief valve
must be installed in the discharge
piping ahead (upstream) of any shutoff
valve (block valve), heat exchanger,
orifice or any potential blockage
point. Failure to install a pressure
relief valve could result in the rupturing
or explosion of some compressor
component.
Do not change the pressure setting of
•
the pressure relief valve, restrict the
function of the pressure relief valve, or
replace the pressure relief valve with
a plug. Over pressurization of system
or compressor components can occur,
resulting in death, severe personal
injury or property damage.
• Never use plastic pipe, rubber hose,
or soldered joints in any part of the
compressed air system. Failure to
ensure system compatibility with
compressor piping is dangerous.
• Never use a flammable or toxic solvent
for cleaning the air filter or any parts.
• Do not remove any guards or cabinet
panels or attempt to service any
compressor part while the compressor
is operating.
• Do not operate the compressor at
pressures in excess of its rating.
• This compressor is designed for
use in the compression of normal
atmospheric air only. No other gases,
vapors or fumes should be exposed to
the compressor intake, nor processed
through the compressor.
• Relieve all pressure internal to the
compressor prior to servicing. Do not
depend on check valves to hold system
pressure.
2 Quincy Compressor-QGB
• Observe control panel displays daily
to ensure compressor is operating
properly.
• Follow all maintenance procedures and
check all safety devices on schedule.
• Never disconnect or tamper with the

General Description
The QGB™ line of rotary screw compressors
covers a horsepower range of 20 to
60. These belt driven compressors
have standard full load pressure ratings
of 100, 125 and 150 PSIG. The large,
127mm rotors allow Quincy to operate
these compressors at lower speeds than
competitive makes.
The compressor is a single stage, positive
displacement, fluid-flooded rotary screw
type unit, consisting of two precisionmachined rotors. The drive rotor is driven
through a v-belt arrangement.
All components are attached to a
heavy-duty steel frame. Controls and
indicators are arranged on a control panel.
Acoustical cabinets are available to reduce
sound levels.
The Compression Cycle
The compression cycle of a rotary screw
compressor is a continuous process from
intake to discharge with no reciprocating
mechanisms starting and stopping as
found in reciprocating compressors. The
compressor consists of two rotors in
constant mesh, housed in a cylinder with
two parallel adjoining bores. The male
drive rotor has four lobes that mesh with
six flutes in the female rotor. All parts are
machined to exacting tolerances.
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
Back to Table of Contents
Section II - Description
When the compressor is operating,
a partial vacuum is produced at the
compressor inlet. Air entering via the air
filter flows through the inlet valve into
the rotor housing where it is compressed,
Cooling System
Air-cooled Fluid Coolers
The air-cooled fluid cooler and aftercooler
are finned aluminum tube design. QGB
20 and 30 horsepower models use a onepiece combination cooler/aftercooler, while
QGB 40 thru 60 horsepower models use
a two-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 receiver 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.
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.
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.
Moisture Separator
A combination moisture separator and
water trap is provided for collecting and
expelling water to the customer’s drain.
Quincy Compressor-QGB

Section II - Description
Back to Table of Contents
Capacity Control System
As the motor starts driving the compressor
rotors, air is drawn in, compressed and
discharged into the air/fluid reservoir.
When the air pressure in the air/fluid
reservoir exceeds the set point of the pilot
valve (normally 100 PSIG), the valve opens
and passes a controlled volume of air to
the inlet valve air cylinder.
The air forces a piston to move within
the cylinder, closing the inlet valve. The
compressor will continue to run, matching
air demand with air delivery by constantly
adjusting the position of the inlet valve.
The inlet valve regulates compressor
capacity between
rated delivery.
When maximum pressure (typically 10
PSIG above normal full load pressure)
has been obtained in the air system,
complete compressor unloading occurs.
The pressure switch located in the control
panel sends a signal to the control and
the solenoid valve opens, venting the
residual pressure from the blowdown valve.
At the same time, control air from the
reservoir check valve is directed through
the solenoid to the inlet valve air cylinder.
The inlet valve is held in a closed position
preventing the intake of air into the
compressor and serving as a check valve
preventing reverse air/fluid flow through
the inlet valve and air filter.

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 Section V - Maintenance
or Service Preparation.
Auto Dual
With the controller set to run in auto dual
mode, a solid state timer is activated
when the unload pressure is reached. This
timer is adjustable within a ten (
range. When the timer reaches the end
of its delay period, the compressor will
automatically shut down and assume a
standby mode. Upon a drop in system
air pressure (to the load set point), the
compressor will restart automatically. The
timer should be set during unit start-up to
a minimum of six (6) minutes.
During the unloaded/timing mode, if
plant pressure drops, the compressor will
continue to operate, resetting the timer
and instructing the inlet valve to reopen.
Continuous Run
When set to run in Continuous Run mode,
the compressor operates continuously,
matching air demand as a differential pilot
valve controls the position of the inlet
valve. When maximum system pressure is
reached, the compressor unloads, venting
the air/fluid reservoir and, although the
compressor continues to run unloaded, no
air is compressed.
Load/No Load
In the Load/No Load mode, the
compressor does not modulate the inlet
valve. The valve is either fully open or it is
closed. If system demands include regular
periods of air usage at less than full load,
a large compressed air storage capability
is required with this type of control.
Without adequate storage, rapid cycling
may occur. This will cause wide system
pressure fluctuations that may affect the
performance of equipment using the
compressed air. Load/No Load works with
Auto Dual control to turn the compressor
off during extended periods of no demand.

Location
Back to Table of Contents
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.
WARNING!
Under no circumstances should a
compressor be installed in an area
exposed to a toxic, volatile or corrosive
atmosphere, nor should toxic, volatile
or corrosive agents be stored near the
compressor.
Section III - Installation
CAUTION!
Clean, fresh air, of sufficient quantity,
is required for proper compressor
operation.
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!
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.
Removal or modification of sound
insulation could result in dangerously
high sound levels.
Quincy QGB™ 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!
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.

Transit Lock
A transit lock is used to secure the motor
platen during shipping to prevent damage
to drive components.
The transit lock is a piece of threaded rod
located between the motor platen and the
compressor sub base. It is marked with a
warning label.
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.
NOTICE!
Once the compressor has been located
and secured at the installation site, the
transit lock must be removed before
operating the unit.
To remove the transit lock, remove the
nuts on the threaded rod and remove
the threaded rod from the mounting tabs
provided on the motor platen and the
compressor sub base.
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.
Pressure Vessels
Air receiver tanks should be in accordance
with ASME Boiler and Pressure Vessel
Code Section VIII.
12 Quincy Compressor-QGB
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.

Relief Valves
Back to Table of Contents
Section III - Installation
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 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.
Electrical
Relief valves are to 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
any personnel. Always direct discharge
from relief valves to a safe area away from
personnel.
Relief Valve
Before installation, the electrical supply
should be checked for adequate wire size
and capacity. During installation, a suitable
fused disconnect switch 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 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 elect r ical enclosures and
components must be appropriate to
the area in which they are installed.

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.”
1926.303 Paragraph 7 published
WARNING!
Cabinet panels and drive guards must
be fastened in place before starting
the machine and never removed before
lock out/tag out of the main power
supply.
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.
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.

Start-up & Operation
The non-cycling design of the refrigerated
dryer assures proper dew point control
at all load conditions. The refrigerant
compressor runs continuously when the
dryer is “ON”. All dryers are installed
with fan cycling switch. These fans will
cycle with respect to the load changes,
ambient temperature fluctuations, and the
cleanliness of the condenser. Standard
units are designed to operate under the
following conditions:
1) Inlet Air Temperature - 100°F design
120°F maximum
2) Inlet Air Pressure - 100 PSIG design
175 PSIG maximum
3) Ambient Air Temperature - 40°F
minimum 110°F maximum
notiCe!
At temperatures above the 100°F
design, refrigeration capacity will
decrease. Operating air pressures
below the 100 PSIG design will reduce
system capacity.
Caution!
STARTING THE DRYER WITHOUT
ENERGIZI N G T H E C R A N K CA S E
HEATER WILL CAUSE PREMATURE
FAILURES OF THE REFRIGERANT
COMPRESSOR. Failure to comply with
procedure of energizing crankcase
heater bef ore star t-up may void
warranty.
Operating Range & Control Settings
(R-134a refrigerant)
Air dryers with three-phase power supply
are equipped with a compressor crankcase
heater. This heater must be energized by
closing the disconnect switch or circuit
breaker a minimum of 6 to 10 hours before
start-up. Power to the air dryer can be left
on to energize the crankcase heater for
the off-cycle, during evening or weekend
shutdowns.
Shutdown Procedure
Turn the power switch to the OFF position.
Caution!
Contact factory before authorizing any
warranty refrigeration service on the air
dryer. Identify the dryer by model and
serial numbers when calling factory.

Maintenance
Back to Table of Contents
Section V - Integrated Dryer (option)
The dryer is factory tested before shipping.
All controls are calibrated for automatic
operation. If the dryer is installed in clean
surroundings, within the temperature limits
of the specified ambient, the dryer will run
trouble-free for a very long time. Routine
maintenance procedures recommended
are the following:
1) Check the fan motor(s) for proper
operation to maintain the cooling air
to be drawn through the condenser
and blown over the refrigerant
compressor.
2) Clean the condenser periodically to
maintain the proper heat transfer on
the condenser coil. Dirty condenser
will raise the head pressure of the
refrigeration system and trip the
compressor “off” at the overload
control. Running the compressor
on high head pressures may cause
premature failures. Check the
ambient temperature limits to be
maintained at the installation.
3) Pressure drop across the dryer may
increase slowly as the particulate
material coming through the air
stream plugs up the internals of
the heat exchanger. A back-flush
procedure is recommended to clean
the air system.
To back-flush, disconnect air dryer, plug
the drain line and fill the air system with
the detergent water solution. Hold it for
4-6 hours. Circulate the detergent from air
outlet to air inlet with a pump. Flush the
system with warm water. If pressure-drop
still exists, contact factory.

Automatic Drains
The recommended settings for the drain
time are determined by the dryer moisture
load. The cycle time should be adjusted to
approximately 2 minutes. The drain time
should be set3-5 seconds, so the drain
expels all of the liquid and then a short
burst of air. These adjustments may be
refined by trail and error method.
Periodically check the automatic drains
for proper drainage. If the drains are not
functioning, the condensed moisture will
be re-entrained downstream of the air
dryer. Electronic solenoid operated drains
may be manually tested periodically for
proper operation.
Drain Valve Clean Up Procedure
A) Depressurize the drain valve.
B) Disconnect the power source.
C) Remove the valve from the
compressed air system.
D) Remove the solenoid coil.
E) Remove the stainless steel sleeve
from valve body.
F) Clean the valve body internals, and
all other components.
G) Replace diaphragm as needed. The
valve rebuild kit is available.
H) Assemble the valve parts.
I) Connect the solenoid coil.
J) Install the drain valve in the system.

Compressor
Refrigerant compressors normally do not
need any maintenance. The compressor
will unload or adjust for different load
conditions with the refrigeration controls.
Any time power is applied to the
compressor, and the suction pressure is
higher than the specified readings, the
compressor is either not pumping or
failed electrically, or tripped “off” at the
overload protection. If the compressor
does not automatically reset within a few
minutes, it requires servicing. Service must
be performed by a qualified refrigeration
technician.
Dual Pressure Switch
This safety switch protects the refrigeration
system. If the refrigerant pressure falls
below or above the normal operating
range, this switch trips the compressor.
Manually reset the switch after rectifying
the fault to run the dryer again.
Expansion Valve
Integrated air dryers are equipped with
a thermostatic expansion valve, factory
set to maintain a superheat of 8 to 10°F.
These valves do not need adjustment in
normal operation. Generally, superheat
adjustments are needed only at the time
of valve replacement. Expansion valve
service must be performed by a qualified
refrigeration technician

Hot Gas Bypass Valve
Integrated air dryers come equipped with
modulating hot gas bypass valves. This
valve maintains the refrigerant suction
pressure in varying load conditions.
The dryer will run from no load to full
load conditions without freeze-up. The
operation of this valve is automatic. If
the valve needs adjustment, turn the
adjusting stem clockwise to raise the
suction pressure, and counterclockwise to
lower the suction pressure. This adjustment
should be made under a no-load
condition. When the adjustment is made,
turn one quarter of a turn at a time, and
wait 3 to 5 minutes between adjustments.
Once the adjustment is complete, secure
the adjusting stem with the locknut that is
provided. Careful adjustment of this valve
is necessary for normal operation of the
air dryer. Hot gas bypass valve adjustment
may be made by maintenance personnel.

Air Filter
Back to Table of Contents
Section VI - Servicing
The standard QGB
™
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.

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
QGB™ 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:
®
at no charge.
• 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.
• 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.
Using a brass drift, tap the shaft
b.
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.
CAUTION!
• Remove the four bolts securing the seal
adapter to the suction housing.
• 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).

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
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.

Differential Pilot Valve
WARNING!
Never adjust the pressure higher than
the factory setting. Death or serious
injury and compressor or property
damage could result.
Open a manual vent valve to allow the
compressor to exhaust air to the outside
and start the unit. By manual regulation,
slowly close the valve, allowing the
unit to build air pressure to the desired
modulation point and hold (100 PSIG
standard). Adjust the screw on the bottom
of the differential pilot valve so that a slight
Pressure Setting
stream of air can be felt coming from the
orifice adjacent to the adjustment screw.
When the air is felt, air is beginning to pass
through the pilot valve to the air cylinder
on the inlet valve, causing the valve to
modulate toward its closed position,
thereby reducing the volume of air being
compressed.
To raise the pressure, turn the adjusting
screw in (clockwise). To lower the pressure,
turn the screw out (counter clockwise).
Maximum full load pressure is
standard QGB™ units. Minimum full load
pressure with modulation and standard
controls is 75 PSIG.
100 PSIG for
The pressure setting determines what
pressure the compressor will load and
unload. Standard factory settings are
listed in the QGB Specifications. If a lower
setting is desired, adjust the differential
pilot valve first and set the pressure cutout point to 15 PSIG over the desired full
load pressure. Refer to HMI Control Panel
Operation in Section IV for instructions
on adjusting the pressure settings. The
pressure settings should unload the
compressor by the time it reaches the 20%
load point. Raising the pressure without
changing the compressor speed above
factory settings will result in high amp
draw and drive belt failures. Consult your
parts book for proper sheave and belt part
numbers.

V-belt Drive Maintenance
Back to Table of Contents
Section VI - Servicing
QGB series compressors are equipped
with an automatic belt-tensioning device
and require no adjustments between belt
replacements.
WARNING!
The automatic spring tensioner system
should not need disassembly. If a
component in the automatic spring
tensioner system is damaged and
needs replacement, be sure to relieve
the tension in the spring before doing
so. DO NOT attempt any adjustments
to the automatic spring tensioner
system without first relieving the
tension in the spring. Failure to do
may result in component damage,
system damage, or personal injury.
Belts must be replaced when
automatic belt tensioning indicator pin
(#8) has reached full length of travel
in its adapter groove. The indicator
pin is used as a visual aid to show the
amount the belts have stretched and
give a visual indication to when the
belts need to be replaced. As the
belts stretch, the spring (#3) along with
motor weight, forces the tensioner rod
(#5) down to keep adequate tension in
the belts. As this occurs, the indicator
pin which is pressed into the tensioner rod
will move down in the slot in the clevis
adapter (#2) that is pinned to the clevis
(#1).
Use caution when working with any
spring assisted mechanism. When
compressed, this spring can release a
significant amount of energy without
warning, causing serious injury.

If at any interval the belts appear to need servicing (show signs of thermal stress or
excessive cracking), there are nicks in the sheave grooves or the indicator pin has
bottomed out in the groove, please contact Quincy Compressor.
2) Thoroughly inspect the tapered bore
of the sheave and the tapered surface
of the bushing. Any paint, dirt, metal
chips, fluid or grease MUST be
removed.
CAUTION!
DO NOT USE LUBRICANTS. Use of
lubricants can cause product breakage
during installation.
3) Position bushing and sheave
assemblies and rough align with a
metal straight edge. Mount sheaves
as close to the compressor and/or
motor housing as practical to avoid
excessive bearing and shaft loads.
With key on shaft, slide loosely
assembled unit onto shaft so that
cap screw heads are on the outside.
Locate unit in the desired position
on the shaft. When installing large
or heavy parts in the conventional
position it may be easier to mount
the key and bushing on the shaft
first, then place the product on
the bushing aligning the holes and
installing cap screws.
CAUTION!
When mounting on a vertical shaft,
insure that the sheave and bushing do
not drop during installation.
4) Tighten cap screws alternately
and evenly to the wrench torques
specified in the bushing data table on
page 5. Note: When tightened there
will be a
the bushing flange and the hub.
1/8” to 1/4” gap between
Should this gap close, then either
the shaft is undersized or the wrong
bushing shaft size is indicated.
CAUTION!
EXCESSIVE SCREW TORQUE MAY
CAUSE DAMAGE TO EITHER BUSHING
AND/OR PRODUCT!
5) Tighten the set screw over the key
and torque to the value listed in the
bushing data table on page 5.
6) Some conditions may exist where
step 5 will have to be completed
before step 4 as the set screw will not
be accessible once the sheave is in
place.
7) After all screws have been torqued
to their proper values, re-check the
alignment. The laser alignment
tool is highly recommended for
aligning sheaves. If the alignment
is out more than two marks on the
laser alignment tool, redo alignment
starting over at step 3.
NOTICE!
Misalignment of the sheaves will reduce
belt and sheave life by increasing
wear and increase the probability of
belt turn over by decreasing stability.
Misalignment comes in three varieties:
Horizontal angular, vertical angular
and parallel. Sheave alignment should
be within .078. This is the total of all
parallel and angular misalignment.
Check sheave misalignment in at least
three places after rotating one of
the sheaves 120 degrees each time,
to locate the position of maximum
misalignment.

Belt Drive Removal Instructions
Back to Table of Contents
1) Remove all bushing cap screws.
2) Install cap screws into threaded jack
holes.
3)
Tighten all jack screws alternately
and evenly, beginning with the screw
farthest from the bushing saw slot,
until bushing grip is released. Slide
sheave and bushing assembly off the
shaft.
Belt Drive Alignment Instructions
Section VI - Servicing
CAUTION!
Excessive screw torque may cause
damage to either the bushing and/or
product. Uneven pressure on jack
screws may also damage the bushing
flange making removal difficult without
damage to the product.
Straight Edge Alignment Procedure
Horizontal Angular (Shafts in same
horizontal plane but not parallel)
1) To check, use straightedge or string
near sheave centers.
2) To correct, loosen motor mounting
bolts and rotate motor until all four
points touch straightedge.
Vertical Angular (Shafts in same vertical
plane but not parallel)
1) To check, place straightedge 1/4
radius from the outside diameter of
both sheaves as shown:
a. Repeat on opposite side of shaft.
b. Straightedge should touch four
points indicated in each position.
2) To correct, loosen sheave so it slides
easily on shaft until all four points
touch straightedge. Tighten sheave in
position. IMPORTANT: Sheave should
be mounted as close to bearing as
possible to reduce overhung load
on bearing. Relocate equipment, if
necessary
Quincy Compressor-QGB

Parallel (Shafts are parallel; sheaves not in
line)
1) To check, use a straight edge or
string near sheave centers.
2) To correct, loosen sheave and
relocate on shaft until all four points
touch straightedge. Tighten sheave in
position. IMPORTANT: Sheave should
be mounted as close to bearing as
possible to reduce overhung load
on bearing. Relocate equipment, if
necessary.
Laser Alignment Procedure
(Recommended)
1) Attach a laser alignment block to
each sheave.
2) Turn on the alignment lasers on each
block.
CAUTION!
Avoid laser contact with the eyes.
3) Check alignment. The figure
below shows how to read the laser
alignment tool. The sum of the drive
and driven misalignment should be
no greater than two marks.
NOTICE!
Never “pry” the belts into the
sheave grooves. This can damage
the belt cords and lead to belt
turnover, short life or actual
breakage. Without exception,
the most important factor in the
successful operation of a v-belt
drive is proper belt tensioning.
Too little tension re s u lts in
slippage, causing rapid belt and
sheave wear. Too much tension
can result in excessive stress on
belts, bearings and shafts.

Deflection Gauge Instructions:
If an o-ring deflection gauge is used to
measure static tension the double barrel
o-ring gauge must be used. The required
deflection distance and deflection force are
provided in the charts above.
Sonic Meter Instructions:
Turn on the power. Press the “Power”
key and the LCD screen display appears
as follows: The LCD screen is back lit for
use in low light conditions. The screen and
back light remain on for up to five minutes
of inactivity, and then the unit automatically
turns off. The opening screen displays the
contents of the data storage register that
was last being used when the STM was
turned off. Values for (1) “MASS” (Belt
Mass Constant), (2) “WIDTH” (Belt Width),
and (3) “SPAN” ( Belt Span Length) are all
displayed simultaneously.
Enter belt mass constant:
M = ____.__ g/m
Belt mass constants are provided on the
charts above. Press the “MASS” key and
enter numbers on the keypad. Make sure
the decimal is placed correctly in the
display panel. If your entry is incorrect,
press “MASS” again and the cursor returns
to the original position.
Enter belt width or number of rib/strands:
W = ____.__ mm/#R
When using the Sonic Tension Meter on
the QGB drives with PowerBand® belts,
be sure to use the appropriate mass
constant and enter the correct number
of belt strands being measured. There is
no need to multiply the mass constant by
the number of ribs/strands, as the Sonic
Tension Meter will calculate the correct
total belt mass.
Example: For a V-belt drive using four
individual 3V belts enter “1” for the belt
width (“Width” key). The Sonic Tension
Meter will display the static belt tension
per individual belt. When measuring the
belt tension in the V-belt drive, make sure
the V-belts do not interfere with each other
while vibrating. If the same drive used a
4-strand 3V PowerBand® belt instead of
single belts enter “4” for the belt width
(“Width” key). The total belt tension for
all four belts is measured as the entire
belt vibrates. The Sonic Tension Meter will
display the total static belt tension for the
PowerBand® belt (for all strands within
belt).

Enter the span length:
S = ____.__mm
The span length represents the distance
between the contact points on adjacent
sprockets/pulleys/sheaves. This distance is
given in mm for each Beta unit.
Measurement
Press the “MEASURE” key and the green
LED light will begin flashing. Tap the belt
span to make the belt span vibrate. Hold
the sensor approximately 1 cm (0.4 inch)
from the belt or closer without touching
the belt. The green LED light will continue
to flash until a signal is received by the
sensor, then the green LED light will turn
off and a wave-form graphic will appear
on the LCD screen. After the signal is
processed, the measured belt tension is
displayed, the meter beeps three times,
and the green LED light turns on indicating
a successful tension measurement. After
a tension reading has been obtained,
pressing the “Hz” key toggles the LCD
display output between tension, frequency,
or both. If the belt signal cannot be
measured, or the measured frequency
or the calculated belt tension is out of
the range of the meter, the red LED light
will turn on. When this occurs, either the
tension or frequency fields may also display
ERROR. To make another tension reading,
simply tap the belt again. The auto-trigger
feature will automatically re-activate the
meter without pressing the “MEASURE”
key.
Tension Display
T = ______ Kgf or lbf or N
The displayed output of measured
force can be switched between units
of Kilograms force, Pounds force, and
Newtons. This can be accomplished as
follows:
With the unit powered off, press the “0”
and “9” and “Power” keys at the same
time. The meter will then turn on with
the current unit of measure displayed.
Units can then be changed by pressing
the “SELECT” key until the desired
unit appears. Press and hold down the
“POWER” key again until the meter turns
off. Now turn the meter on for normal
operation. Data entered into the unit must
still be in SI units of millimeters and grams.
Frequency Display
F = ___Hz
Pressing the “Hz” key toggles the LCD
display output between tension, frequency,
or both.
Measurement Errors
If either the calculated belt tension or
measured frequency cannot be displayed
the red LED light will turn on and the
LCD screen may display “ERROR”. If an
error has been made in the measurement,
“ERROR” will be displayed. Check the
accuracy of the mass constants, width and
span values and retry the measurement
until a tension or frequency value is
displayed. With the auto-trigger feature it
is not necessary to press the “Measure”
key again. When a tension or frequency
reading is obtained, take at least two
additional readings for comparison.
Three readings in relative close proximity
indicate reasonably accurate belt tension
readings. Tension measurements made
on belts at very low tensions may yield
greater variability and a greater probability
for errors. If a tension reading cannot
be obtained, the belt may be too loose
to generate a clear harmonic frequency
signal. If this is the case, the belt may need
to be tightened in order to obtain a tension
reading. The optional Inductive Sensor
is more effective at very low frequencies
than the conventional microphone sensors,
and may provide better results. NOTE:
Frequency only readings must have data
values in the storage registers or the
meter’s red LED light will stay on.

Lubrication
Back to Table of Contents
Section VII - Compressor Fluids
Most Quincy Compressors are equipped
with a positive displacement fluid pump
mounted to the compressor and directly
driven by one of the rotors. 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. Models not equipped

Fluid level is monitored by a sightglass or
a dial gauge while in operation. Fluid level
should be in the “run” area on the dial
gauge or completely fill the sight gauge.
DO NOT OVERFILL.
with a fluid pump use pressure differential
to circulate the fluid. Positive pressure
maintained in the reservoir forces the fluid
throughout the machine.
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.

the machine before proceeding.
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

Fluid Filter
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.
NOTICE!
Use genuine Quincy replacement
filters only.
Figure 1-3. Spin-on Fluid Filter
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:
• as indicated by the fluid filter
maintenance indicator when the fluid is
at normal operating temperature
• every 1,000 hours
• every fluid change
NOTICE!
The fluid filter maintenance indicator
may read high upon start up on
cool mornings due to sluggish fluid
creating higher than normal differential
pressures. Monitor indicator after the
fluid warms up.
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
Back to Table of Contents
Quincy’s fluid analysis program is offered
to all customers using QuinSyn fluids
in Quincy Compressor
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
®
Rotary Screw
Section VII - Compressor Fluids
®
and sent to Quincy Compressor
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.
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.
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.

QuinSyn PG
QuinSyn PG is a custom blended
polyalklene glycol/ester (PAG). QuinSyn
PG is an ISO 46 viscosity fluid with an
8,000 hour life under normal operating
conditions (exact fluid life is determined
by the fluid analysis program) and is the
chosen fluid for Quincy’s new five-year
airend warranty effective June 1, 2000 (see
Blue Alert #566). Under extended warranty
conditions QuinSyn PG fluid life is rated at
8,000 hours or one year, whichever occurs
first.
Typical Properties of QuinSyn PG ISO 46
Viscosity @
Viscosity @ 210°F ASTM D445 9.4 cSt.
Viscosity Index ASTM D2270 163
Specific Gravity 60/60 0.98
Flash Point ASTM D92 485°F
Fire Point ASTM D92 525°F
Applications
QuinSyn PG is the recommended fluid in
high humidity applications due to its ability
to hold water. 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
100°F ASTM D445 52.4 cSt.
this fluid from condensate will require
those separators designed to handle
fluid emulsions. The QIOWA 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. The new five-year extended
warranty with QuinSyn PG requires
2,000 hour sampling as a condition of
maintaining the warranty.
NOTICE!
To maintain warranty compliance, fluid
samples of QuinSyn PG must be sent
to Quincy Compressor® Fluid Analysis
a minimum of every 2,000 hours.
Because this fluid differs from QuinSyn,
different methods are employed to
evaluate the fluid in the sampling program.
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 we have set
low limits for this additive (see page 60 for
limits).

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 QIOWA 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.

Converting to QuinSyn
QuinSyn fluids are compatible with the
materials and elastomers used in mineral
oil systems. Converting your compressor
from mineral oil to QuinSyn or QuinSyn IV
may be as easy as a simple flush to remove
any sludge and varnish present. Emphasis
must be placed on draining after each
step. Contaminants left in the compressor
after flushing have a direct effect on the
fluid’s life. Once the oxidized material
(varnish) is dissolved in the QuinSyn Flush,
the cleaner and varnish must be removed
from the compressor and system parts
(particularly in areas like filters, coolers
and piping, etc.). See your Quincy
Compressor® Distributor to assist in the
evaluation of your compressor.
