Page 9: Section Ii - Description
Section II – Description 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. -
Page 10: The Compression Cycle
QSF specifications. The cooler fins must be kept clean at all times. Fluid leaving the receiver passes through a thermal mixing valve before traveling on to the cooler. The purpose of the thermal valve is to maintain a minimum fluid discharge temperature at the compressor of approximately 180 Fahrenheit. Quincy Compressor – QSF Series... -
Page 11: Modulation Control Standard
Auto/Dual Standard The Auto/Dual system is standard on the Quincy QSF Compressor. The control uses a programmable timer to shut the compressor down if it stays unloaded for the programmed time period. The timer should be set during unit start up for a minimum of six (6) minutes. -
Page 12: Electrical System Description
F. They are not suitable for salt laden, corrosive, dirty, wet or explosive environments. The QSF series compressors utilize 460V incoming power through a magnetic motor starter. A transformer in the control panel reduces this voltage to 120 VAC for the various controls on the unit, which is then reduced to 24 volt for the electronic controls. -
Page 13: Indicators
This indicator signals when the filter element needs to be cleaned or replaced on the QSF. NOTE: Both the standard and stock versions include a programmable change interval timer on the air filter, fluid filter and the air/fluid separator element. Quincy Compressor – QSF Series... -

High temperature shutdown may result. All models are intended for indoor installation; however, it is possible, with certain modifications, to accommodate some outdoor locations. Cabinet models are water-resistant but not water tight. Sheltering from rain, snow and freezing temperatures is mandatory. Quincy Compressor – QSF Series... - Page 15 The Quincy QSF models are essentially vibration free; however, some customers may choose to bolt the unit to the floor to prevent the accidental breakage of piping or electrical connections as a result of being bumped.

See control panel for the proper wiring diagram. Quincy would like to emphasize the importance of providing adequate grounding for air compressors. The common practice of grounding units to building structure steel may not actually provide adequate grounding protection, as paint and corrosion build-up may exist. -

PSI maximum. Water temperature should be 50°F minimum/90°F maximum. Clean air is essential for your Quincy QSF compressor. Always select a source providing the cleanest air possible. When an outside air source is used, keep all piping as short and direct as possible. Use vibration isolators and support all piping correctly. -

Fluid Specifications We recommend that all Quincy gear drive rotary screw compressors be filled with QuinSyn IV or QuinSyn synthetic fluid. QuinSyn IV or QuinSyn is available from any authorized Quincy distributor. For applications requiring a food grade fluid, we recommend QuinSyn F. Sustained (3 hours or more) of discharge temperatures over 210 F, require the use of QuinSyn HP fluid. -
