Industrial Air Power Redefined with the R-70 Pump
The Champion BR20 is built for high-volume, continuous-duty industrial performance.
Equipped with the robust R-70 cast-iron two-stage pump, this 20 HP base-mounted compressor delivers 77.8 CFM @ 175 PSI while operating at only 664 RPM, producing more air at a slower speed for cooler, quieter, and longer-lasting operation.
The BR20 is designed for integration into central air systems, multiple-user setups, or installations that require a dedicated compressor without a tank — offering efficiency, reliability, and true industrial strength.
R-70 Pump vs. R-40 Pump — The Next Evolution in Performance
Champion’s R-70 pump is a significant upgrade from the R-40. Both are precision-machined, cast-iron, two-stage designs built for endurance, but the R-70 offers greater displacement, larger valves, and enhanced cooling capacity for heavy-duty applications.
