Rotary Screw Compressor

The Quincy QSF

Is quiet, efficient, and when it comes to top quality, fluid-flooded Rotary Screw Compressors you can count on the Quincy QSF. Backed by an optional five-year factory airend warranty, the QSF ensures dependability. In addition, the QuincyQSF features as standard: microprocessor control, Wye-Delta reduced voltage starting, and oversized coolers that facilitate operation in ambient temperatures up to 110º F. Securing your sound investment, the QuincyQSF optional enclosure attenuates sound levels as low as 74dBA.

Long running advantage

Time tested tapered roller bearings support each rotor on the discharge end with cylindrical roller bearings on the inlet end - giving the QuincyQSF a 100,000 plus hour life expectancy. Plus, the QuincyQSF has a triple lip seal on the drive shaft that prevents fluid from escaping the airend and an internal scavenge between the seals that carries any migrating fluid back to the airend. This redundant seal system adds up to lower maintenance costs and years of performance.


Inside the QSF

Sound investment

The QuincyQSF employs standard drive motors with a NEMA C-face mount for permanent alignment of the drive coupling. When combined with the QuincyQSF optional enclosure, sound levels can be as low as 74dBA. Hinged enclosure panels allow for convenient maintenance and easy access to service components.

Enhanced Capabilities

Now, when it comes to accommodating even the most demanding conditions, the Quincy QSF is second to none. Operation temperatures are hot, especially in compressor rooms. This is why the Quincy QSF is designed with oversized fluid coolers and aftercoolers allowing the enclosed Quincy QSF to operate efficiently in ambient temperatures as high as 110º F.

The QuincyQSF manages compressor capacity to match system demand through electronic control. Standard control is modulation with unload capability to reduce horsepower when demand decreases. The QuincyQSF can also operate in load/no-load and auto dual mode (timed shutdown), ensuring maximum load flexibility while offering overall energy efficiency.
