Quincy QR-25® Features & Benefits

Quality Features Performing Quality Functions
-	Intake unloaders allow for loadless starting, system flexibility, energy savings and less wear & tear on motor	-	Aluminum connecting rods with oil passage for full flow lubrication to piston pins to extend compressor life
-	Individaul valve pockets allow easy access for routine maintenance	-	Rifle-drilled, counterweighted one-piece crankshaft reduces vibration, extends life of bearings and wrist pins
-	High-pressure pistons are cast iron for strength and long life	-	Hydraulic unloader protects compressor if oil pressure drops below normal (when loadless starting or dual control is specified)
-	Cast iron cylinders maintain rigid tolerances for high efficiency	-	Pressure lubrication with positive displacement oil pump to assure constant lubrication of all critical wear areas
-	Intercooler has large circular fins for maximum heat dissipation and longer life	-	Spin-on oil filter for convenient, clean lubrication
-	Tapered roller bearings are oversized and easily adjusted for trouble-free operation	-	Slow speed operation requires less maintenance, produces more CFM per horsepower
-	Cast iron crankcase and flywheel for strength & durability	-	Loadless starting for lower energy costs and less wear on motor
-	Cast iron valve seats are lapped for a total seal, eliminating need for discharge line check valve	-	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
-	Valve design lets the QR-25® run efficiently at lower temperatures
-	Steel valve discs use low-lift design for better efficiency and less downtime	-	Safe-Q-Lubrication permist the compressor to start load-free until oil pressure rises high enough to close the hydraulic unloader
-	Two-stage capability: 200psig at continuous ooperation, up to 500 psig intermittent on certain models	-	Dual oil filtration, first at the oil pick-up tube, second through the spin-on oil filter
-	Rebuildable components	-	Low maintenance requirements
-	Manually reversable oil pump	-	Dual control available as an option
