The QR-25 is pressure lubricated in all critical areas, runs at slower speeds, and features durable cast iron construction for longer life and less downtime. Please take a look at the legendary heritage of the QR-25 below.
Reciprocating/Piston Air Compressors
A reciprocating air compressor is a positive-displacement compressor that uses a crankshaft-driven piston and cylinder to compress the air. A single-stage reciprocating piston compressor works by drawing the air into the cylinder where it is compressed in a single-piston stroke of approximately 120 PSI and then sent to a storage tank. A two-stage compressor includes an additional steps where the air is compressed by a second, smaller piston to a pressure of up to 175 PSI.
Compressors decrease the amount of space air takes up by compacting it. A reciprocating compressor is a positive-displacement air compressor that uses a crankshaft-powered piston and cylinders. Our piston air compressors use either a single- or two-stage process to compress air.
Compressing air decreases its volume and increases its density without changing it to liquid. Here is how a reciprocating air compressor works:
- Gas enters the cylinder through the intake valve.
- The piston pulls away from the intake valve and allows the gas to pass into the cylinders.
- The crankshaft powers the piston, which compresses the gas in one stroke of about 120 pounds per square inch (psi) of pressure.
- In two-stage compressors, air travels to a second cylinder for another round of compression. A second piston compresses the gas at a pressure rate of 175 psi.
- Once complete, the compressed air is sent to a storage tank for use.
Features
- Intake unloaders allow for load less starting, system flexibility, energy savings, and less wear on the motor.
- Cast-iron valve seats are lapped for a total seal, eliminating the need for a discharge line check valve.
- Individual valve pockets allow easy access for routine maintenance.
- Steel valve discs use a unique low lift design and cast-iron bumpers for increased
efficiency and less downtime. - High-pressure pistons are cast-iron for strength and long life.
- Cast-iron cylinders maintain rigid tolerances for high efficiency.
- Aluminum connecting rods with oil passage for full flow lubrication to piston pins to extend compressor life.
- Intercooler has large circular fins for maximum heat dissipation and longer life.
- Rifle-drilled, counter-weighted, one-piece crankshaft reduces vibration, extends life of bearings and wrist pins.
- Hydraulic unloader and Safe-Q-Lube protects compressor if oil pressure drops below normal (when loadless starting or dual control is specified).
- Tapered roller bearings are oversized for trouble-free operation.
- Pressure lubrication with positive displacement oil pump to assure constant lubrication of all critical wear areas.
- Cast-iron crankcase and flywheel for strength and durability
- Spin-on oil filter for convenient changes and clean lubrication.
Quincy Compressor QR-25 Specification & Warranty
Reciprocating air compressors are compact options workers can apply to natural gas processing and delivery and oil refining. These air compressors work across industries to give you powerful compression.
Our premium, top-of-the-line pressure lubricated piston air compressor is the QR-25. It’s a heavy-duty compressor that is pressure lubricated in all critical areas and delivers up to 25 hp. Available in single- and two-stage versions, the QR-25 is designed to operate at slower speeds and is equipped with intake loaders that minimize work. The rugged cast iron construction ensures a long life expectancy, less downtime and easier maintenance. Other key features include loadless starting, a manually reversible oil pump and rebuildable components. Seen as the industry standard in piston compressor technology, the performance of Quincy’s QR-25 is legendary.
STANDARD QUALITY FEATURES
- Slow speed operation requires less maintenance, produces more CFM per horsepower.
- Valve design lets the Quincy QR-25 run efficiently at lower temperature,
eliminates need for discharge line check valves. - Load less starting for lower energy costs and less wear on motor
- Intake unloaders reduce horsepower when demand is low, which lowers operating
costs and extends valve life - Intake unloaders also unload the intercooler for optimum unloaded horsepower
- Safe-Q-Lubrication permits the compressor to start load-free until oil pressure rises to engineered setting to close the hydraulic unloader
- Crankshaft throws have babbit inserts to protect the running surfaces of the rod and crankshaft
- True Blue 5 Year Warranty
