General Description of Quincy QSF Series Air Compressors
The compressor is a single stage, positive displacement, fluid-flooded helical screw type unit. The
compressor consists of two precision-machined rotors. The male rotor is driven by a gear train,
connected to motor shaft through a flexible drop out type coupling. The male rotor has four lobes that
mesh with a female rotor consisting of six flutes. Both rotors are housed in a single cast iron cylinder.
The unit has an inlet port at the power-input end and a discharge port at the opposite end.
All models use positive pressure in the reservoir to circulate fluid through the system.
All components are attached to a heavy-duty steel frame. Controls and indicators are arranged on a
control panel. Acoustical cabinets are available to reduce sound levels.
