Reciprocating Compressor

QR: Unmatched Reliabilities

Not everyone can offer an industry standard. The Quincy® QR-25 is the industry standard for reciprocating compressors. Because the QR-25 runs at slower speeds than other compressors, it has a lower operating temperature and achieves maximum compressor efficiency. The QR-25 features durable cast iron construction for longer life and less downtime, and heavy-duty disc-type valves for efficient air flow. The result is more air per horsepower. And the QR-25 series gives you unmatched flexibility. Choose horsepower from 1/3 to 25, choose single stage or two-stage, or choose base mount or tank mount. No matter which QR-25 model you select, you're choosing Quincy Quality. Because of that quality, the QR-25 is backed by the most comprehensive five-year warranty in the business. It's the standard of durability, commonly in use for 20, 30, even 40 years

Quality features performing quality functions Intake unloaders allow for loadless starting, system flexibility, energy savings, and less wear and tear on motor Individual valve pockets allow easy access for routine maintenance High-pressure pistons are cast iron for strength and long life Cast iron cylinders maintain rigid tolerances for high efficiency Intercooler has large circular fins for maximum heat dissipation and longer life Tapered roller bearings are oversized and easily adjusted for trouble-free operation Cast iron crankcase and flywheel for strength and durability Cast iron valve seats are lapped for a total seal, eliminating need for discharge line check valve. Valve design lets the QR-25 run efficiently at lower temperatures Steel valve discs use low-lift design for better efficiency and less downtime Aluminum connecting rods with oil passage for full flow lubrication to piston pins to extend compressor life Rifle-drilled, counterweighted one-piece crankshaft reduces vibration, extends life of bearings and wrist pins Hydraulic unloader protects compressor if oil pressure drops below normal (when loadless starting or  dual control is specified) Pressure lubrication with positive displacement oil pump to assure constant lubrication of all critical  wear areas Spin-on oil filter for convenient, clean lubrication Slow speed operation requires less maintenance, produces more CFM per horsepower Loadless starting for lower energy costs and less wear on motor Intake unloaders reduce work and horsepower when demand is low, thus lowering operating costs and extending life. They also unload the intercooler for the lowest unloaded horsepower possible. Safe-Q-Lubrication permits the compressor to start load-free until oil pressure rises high enough to close the hydraulic unloader. Dual oil filtration, first at the oil pick-up tube, second through the spin-on oil filter.
