Superior Energy Savings Capability
Example:
To analyze: QGD45kW / 8 Bar compressor, the demand air of a
customer/1year: 3x106m3 (a 45kW compressor delivers air in full
operation: 1year/6000hours), total power consumption is:
Quincy Compressor:6.4 kW/(m3/min)/60 x 3x106=320000 kW·h
1Class Compressor:7.2 kW/(m3/min)/60 x 3x106=360000 kW·h (Save 11.2%)
2Class Compressor:8.1 kW/(m3/min)/60 x 3x106=405000 kW·h (Save 21%)
If electric power cost is RMB1/ kW·h，the customer will realize the
benefit of reduced operational costs with the Quincy compressor
in 1 year:
Quincy comp. VS. 1 Class compressor: (360K- 320K)x1= RMB 40,000
Quincy comp. VS. 2 Class compressor: (405K- 320K)x1= RMB 85,000

Inlet Air System
Fresh Air for the compressor &
cooling the motor is drawn
directly from outside the
enclosure.
Raises operational efficiency.
 Fresh air improves cooling
conditions.
 The entire enclosure and
silencing compartment is padded
with sound absorbing foam to
lower sound levels.

Fluid / Air Separation System
Specially designed fluid/air separator element ensures
minimal oil carryover
Using centrifugal separation / gravity prior to separator
& element, the combined effect lowers oil carryover to 3
ppm or lower.
Safety Relief Valve for high pressure protection
QUINCY ROTARY SCREW AIR COMPRESSOR
QGD/QGV 30-90kW
Lubricant System
Fluid Filter：Quincy high efficiency
glass microfiber fluid filter provides
absolute Air End protection.
Spin-on fluid filter cartridge allows
quick change-outs.
 Imported high quality Thermal Control
Valve ensures machine operating
conditions are stable and constant.
PTFE high pressure tubing, with
stainless steel metal exterior protection,
for extended tube lifetime.
QUINCY ROTARY SCREW AIR COMPRESSOR
QGD/QGV 30-90kW
Cooling System
 Centrifugal fan – low sound levels,
low power consumption. Quiet and
Efficient.
 “Air Suction” design for higher
efficiency.
 Reliable operation in ambient
temperatures as high as 46 ℃.
 Designing for discharge of hot air
through the top of the compressor,
facilitating ducting for hot air
discharge or energy recovery
installations.

Reduced Vibration Design
 Vibration isolators are fitted
at 3 points under permanently
aligned motor and Air End,
effectively absorbing vibration.
Flexible pipe Coupling is
suitably used where required
resulting in lower noise and
vibration.
