Profile: Quincy Compressor is a manufacturer of rotary screw and reciprocating air compressors and vacuum pumps. These products are marketed through Quincy's domestic and international distribution system. The new Quincy global belt series of rotary screw compressors is created specifically for light and medium industrial applications. Our air compressor systems are designed and engineered to provide the most cost effective compressed air production possible. These compressors have special lap gap rings that limit oil carryover to less than 2 ppm. Our specialization in compressed air has resulted in excellent pressure control products that stop fluctuating plant header pressure, as well as automation controls that deliver the most efficient compressor arrangement for a plant.
