This raises efficiency and improves cooling conditions. The entire enclosure and silencer compartment is padded with sound absorbing foam to lower sound levels. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW 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. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW 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. QUINCY ROTARY SCREW AIR COMPRESSOR 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. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW The QUINCY Airend Oversized Rotors High Efficiency, Lower Power Consumption, Airend Life of 130,000 hours QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW The QUINCY Airend Oversized Bearings Oversized bearings last longer. Discharge end triplex tapered roller bearings for stable operation and increased compressor life. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW 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. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Drive 380V/3P/50Hz IP54（TEFC） motor from renowned Chinese manufacturer. “C” flange connected motor and airend for permanent shaft alignment. Direct drive, no belts/gears/coupling, hence no transmission losses. Flexible dropout coupling. Stable reliable operation. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Electronics and Controls Main Electronic & Control Components Wye-Delta reduced voltage starters and electronic components use SIEMENS branded components.

Multiple network sequence design and options. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW 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. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Lubricant System Quincy high efficiency glass microfibre fluid filter is designed for full flow for total protection. Imported high quality thermal control valve ensures operating conditions are stable and constant. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Quinsyn Fluids Uses Quincy QuinSyn line of synthetic fluids - standard factory fill being QuinSyn- PLUS fully synthetic fluid Varnish free operation High viscosity index Excellent corrosion protection Water holding capability Efficient cooling QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Cooler Pack 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℃. Aftercooler approach temperature is 8℃ or lower Fluid Cooler & aftercooler are mounted separately to prevent resultant cooler 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. QUINCY ROTARY SCREW AIR COMPRESSOR QGD 110-160kW Piping System Air piping joints are flange connected. Flexible hose is suitably used where required. Leak-free and fuss-free installation/dismantling.
