Compressor Airend
 A standard C-Face mounted motor ensures that the motor
and compressor will be properly aligned when the
compressor leaves our factory… and stays that way.
 The integrated mounting flange allows access for coupling
maintenance. The flexible dropout coupling can be replaced
without removing the motor!
 A cartridge-style, triple-lip seal arrangement ensures the oil
stays in and contaminants stay out.
 Designed to be direct driven
with no gears or belts involved.

Fluid/Air Separation System
Separator Element
 Integral separator element module.
Modular design reduces complicated
piping connections for easy installation
and maintenance.
 “Enclosed” one-piece construction
allows quick-change without disconnecting
discharge piping – simple servicing.
 High efficiency separator element
ensures oil carryover of 1~ 3ppm.

Fluid System
 Integral thermostatic valve and fluid filter
element. Modular design reduces piping
for easy installation and maintenance.
 “Enclosed” one-piece construction allows
for quick-change without having to
disconnect other components for simple
servicing.
 High efficiency glass microfiber fluid filter
provides absolute protection to the airend.
QUINCY ROTARY SCREW AIR COMPRESSOR
QGL 15-37kW
Fluid System
 Uses QuinSyn line of synthetic
fluids - standard factory fill being
QuinSyn PLUS, a fully synthetic
fluid
 Varnish free operation
 High viscosity index
 Excellent corrosion protection
 Water holding capability
 Efficient cooling
QUINCY ROTARY SCREW AIR COMPRESSOR
QGL 15-37kW
Cooling System
 Oversized cooler ensures
reliable operation in ambient
temperatures as high as 46 ℃
 Aftercooler approach
temperature as low as 8℃
 Designing the discharge of hot
air from the top of compressor
facilitates energy recovery
installations
QUINCY ROTARY SCREW AIR COMPRESSOR
QGL 15-37kW
Piping System
 Oil piping uses prefabricated
steel pipes: neat layout, assured
performance and reliable.
 SAE “O”-ring fittings provide the
most reliable sealing at joints

QGL 15-37kW
Intelligent Control
 LCD display，simple and high clarity interface
 Measurement Unit selection (psi/bar, ℃/℉)
Comprehensive Protection ：

High temperature shutdown

Low temperature shutdown

High pressure shutdown

Motor overload shutdown

Power fault shutdown

Phase/Pressure/Temperature monitor
 Temperature transducer and temperature
sensor for double-protection
 Service timer/reminder
QUINCY ROTARY SCREW AIR COMPRESSOR
QGL 15-37kW
Intelligent Control（continuation）
 Time-delay restart to avoid starting loaded.
 Control options：
Continuous Run: load/unloads according to system demand
without shutdown.


Auto-dual: allows compressor to shut down for energy savings.
Auto-restart: allows compressor to automatically re-energize
and return to service after loss of incoming power.

Options：
 Pressure switch control：the compressor can continue to run
if the pressure transducer is fails.
 MODBUS communication protocol：for remote monitoring and
control of compressors via RS485 network

Gauge Control
 Gauge display: stable and reliable
 Standard protection：

High temperature shutdown

High pressure shutdown

Motor overload shutdown

Power fault shutdown

Phase monitor
 Two control options：

Continuous Run：load/unload, no shutdown
Auto-dual：load/unload, with timed shutdown
for energy savings.

Electronic System
 Wye-delta reduced voltage
starter
 Uses Siemens components
for reliability and quality
 Phase monitor is standard,
for protection against phase
loss, unbalanced voltages
or phase reversals.
