3. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 Inlet Air System POWERCORE Inlet Filter Element (Patented Technology) • Particle removal down to 3 micron at 99.9% efficiency for complete system protection. • Long service life, easy change-out of filter element.

4. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 Inlet Air System Quincy Positive Closure Inlet Valve • capacity range from 0% to 100% by On/Off control model, simple and reliable. • Positive closure inlet valve eliminates current peak penalties during start up. • The inlet valve is closed completely against the fluid return.

5. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 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.

6. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 The Quincy Airend Oversized Rotors • High Efficiency, Lower Power Consumption, reliability. • Oversized rotors:Ø321 mm

7. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 The QUINCY Airend Oversized Bearings • Oversized bearings last longer. • Discharge end triplex tapered roller bearings for stable operation and increased compressor life.

8. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 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.

9. QUINCY ROTARY SCREW AIR COMPRESSOR QSI200-280 Drive Train • 380V/3P/50Hz IP54（TEFC）motor from renowned Chinese manufacturer. • Direct drive, no belts/gears/coupling, hence no transmission losses. • Flexible dropout coupling. Stable reliable operation.
