Loaded with rugged features, the Champion R-Series splash-lubricated compressors deliver high performance, long life and tremendous value.

1 Multi-finned cylinders - Cooler operating temperatures result in longer life and consistent performance over time.

2 Integral cylinder/head - Gasketless design eliminates the possibility of blown head gaskets for trouble-free operation.

 3 Balanced pistons - Aluminum alloy first-stage piston is weightmatched to the cast iron second-stage piston, ensuring proper balance.

 4 Piston rings - Two compression rings and one oil control ring provide excellent oil control, and high efficiency air delivery.

 5 Lightweight connecting rods - High-density, die-cast aluminum alloy rods minimize reciprocating weight. An integral, precision-bored crankpin bearing and a needle bearing for the piston pin properly distribute bearing loads for longer bearing life than bushings.

 6 Pressure relief valves- Located in interstage and discharge.

 7 Intercoolers - Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency.

 8 Optimized cooling fan/flywheel - Precision balanced flywheel has fan blades for optimum compressor cooling and life.

 9 Reliable, high-flow valves - Single-unit, disc-type valves provide low lift and long life. Discs are made of corrosion resistant Swedish steel. Valves are easily serviced by removing the manifolds only.

10 Oversized main bearings - Tapered roller-type main bearings provide full contact and support of the crankshaft plus delivers the longest possible life.

 11 Balanced crankshaft - Constructed of rugged ductile iron with large diameter throws for minimum bearing loads and counterweights to minimize vibration.

 12 Large capacity crankcase - Rugged cast iron oil reservoir has convenient sight gauge glass, corner oil fill boss and large oil drain.

 13 Loadless starting - Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.

Compressor Pump Warranty

Each new Champion Assembled Unit has a five (5) year warranty on the compressor pump only, against defects in materials or workmanship under normal use and service, from the date of installation or sixty-six (66) months from the date of shipment by Champion or a Champion distributor, whichever may occur first. 

The five-year extended warranty covers parts and labor and is prorated over the five years as follows:

Year One — 100% coverage
Year Two — 90% coverage
Year Three — 80% coverage
Year Four — 70% coverage
Year Five — 60% coverage

Head valves are warranted for Year One only. Champion makes no warranty on components and/or accessories furnished to Champion by third parties, such as electric motors, gasoline engines and controls. These are warranted only to the extent of the original manufacturer’s warranty to Champion.

Electric motors must be equipped with thermal overload protection to have warranty consideration.  The extended five-year warranty will apply to ASME air receivers if they are installed on rubber vibro isolator pads or approved equivalent.

5-Year Electric Motor
Any Champion package purchased after January 1, 2003 built with a Baldor electric motor are warranted for 60 months from start-up or 63 months from shipment. Other manufacturer’s motors furnished due to customer request or special requirements carry the motor manufacturer’s warranty.

Limited Warranty
Warranty shall not apply to any equipment, which has been subjected to misuse, neglect or accident, nor shall it apply to any equipment that has been repaired or altered by any person(s) not authorized by Champion. Failure caused by lack of proper maintenance is not covered by warranty.

In no event shall Champion be liable for consequential damages or contingent liabilities arising out of failure of any compressor or part to operate properly. When a compressor pump or component is changed or replaced during the warranty period, the new/replaced item(s) is warranted for only the remainder of the original warranty period. Complete warranty details are included in compressor operating manual.

Package Warranty
Champion warrants each new air compressor package to be free from defects in material and workmanship under normal use and service for a period of one year (12 months) from the date of installation or 15 months from the date of shipment by Champion.

U.L. Standards
Champion, in common with other major, industrial compressor manufacturers, does not market compressors, which are

U.L. listed. In general, U.L. is concerned with electrical components that may be utilized on compressor units, rather than a complete compressor package or system. All electrical components used on Champion compressors are

U.L. listed. Each component – motor, starter, pressure switch, control panel – carries a U.L. identification mark on the nameplate or inside the electrical enclosure cover. The mark will be the letters “UR” reversed (as if held up to a mirror), indicating the item is “recognized” by U.L. On tank mounted units, the air receiver tank and tank pressure relief valve are ASME Code. The tank carries a National Board Registration number, which appears on a stamped, metal plate welded to the tank.
