Champion R-15B

The Champion R-15B is a two-stage cast-iron bare replacement pump for Champion R-Series reciprocating compressors – the air-end and flywheel only, supplied with no motor and no receiver tank. It is rated to pair with 3-7.5 HP motors and drives compressed air to 175 PSI when mounted to a host tank. Construction is two-stage, splash-lubricated cast iron built for sustained industrial duty in automotive service, fabrication, and production settings. The R-15 pump is the air-end used in complete units such as the HR7F-8 (80-gallon); sold on its own as the R-15B it includes no tank. Because delivered flow depends on the paired motor and speed, confirm displacement and motor pairing with a certified Champion distributor.
