Inlet Air System
Design of Inlet Air
Silencer Compartment
Inlet Air for the
compressor & air required
for cooling the motor is
drawn directly from outside
the enclosure. This raises
efficiency and improves
cooling conditions.
The entire enclosure and
silencer compartment is
padded with sound
absorbing foam to lower
sound levels.

Inlet Air System
POWERCORE Inlet Filter Element
(Patented Technology)
Patented Technology.
Performance is 10 times
better than traditional paper
elements. Pressure drop is
low – raises efficiency of the
compressor.
Particle removal down to
3 micron at 99.9% efficiency
for complete protection.
Long service life, easy
change-out of filter element.

Inlet Air System
Quincy Positive Closure Inlet Valve
Capable of modulation with capacity
range of 20 – 100 %, which is higher than
machines of similar competing lines. The
wide modulation band ensures stable
pressure in air supply, reduces energy
consumption due to varying load
changes and extends the life of the motor.
The positive closure inlet valve is able
to close totally. During unload, air enters
the airend from the bypass valve. If there
is a sudden loss of supply power or in the
event of emergency stop, the inlet valve
completely closes and prevents a fluid
backflow. The inlet valve operates using
pressure from the reservoir and makes
operation stable and reliable.

QGD 110-160kW
The QUINCY Airend
Axial Flow Inlet
The directional flow inlet
housing chambers the air
flow towards the rotor
housing in an axial
direction, reducing
turbulence that would
cause an increase in
temperature of inlet air.
Drawing air into a
chamber ahead of the
rotors allows the full length
of the rotor to be used.
The result is improved
efficiency by 5% to 7%
over traditional radial flow
designs.

Oversized Bearings
Oversized bearings last
longer.
Discharge end triplex
tapered roller bearings for
stable operation and
increased compressor life.

The Quincy Airend
Airend Shaft Seal
Triple lip PTFE shaft seal
assembly
Outer dust seal protects
the triple lip seal and forms a
scavenge cavity.
Scavenge cavity is linked
to the inlet valve via a return
line and the vacuum ensures
no fluid leakage.
The scavenge line is
equipped with a check valve
that prevents any fluid from
following from the airend to
the scavenge cavity when
compressor is shut down.

Fluid/Air Separation System
All new separation
technology, modular multipleseparator design, that
provides larger surface area
for fluid/air separation.
Using centrifugal
separation & gravity prior to
separator, the combined
effect lowers oil carryover to 3
ppm or lower.
All connecting pipework is
designed to the sides of the
reservoir. Separator element
change can be accomplished
without disconnecting any
pipes. Design is ergonomic.

leakage from thermal stresses
QUINCY ROTARY SCREW AIR COMPRESSOR
QGD 110-160kW
Cooler Pack
Designing the discharge of hot air
through the top of the compressor facilitates
ducting for hot air discharge or energy
recovery installations.
Suction-type coolers and venting the hot
air discharge via top of the compressor also
lowers sound levels.
The horizontal air ducts for ventilation
within the enclosure keep the temperature
rise to 6℃ or lower,ensuring adequate
cooling for the motor. The size of the inlet
ducts can be adjusted to regulate cooling to
suit operating under different conditions.
Aftercooler is fitted with moisture
separator.
Water cooled option available.
