Industrial Air Performance Built for Demanding Environments

The Champion HR20-12 delivers rugged, continuous-duty performance for manufacturing facilities, automotive production, and industrial plants that require large-volume, high-pressure air.
Powered by Champion’s proven R-70 cast-iron two-stage pump, this compressor produces 77.8 CFM @ 175 PSI while running at only 664 RPM, ensuring efficient, cool, and quiet operation with long service life.

The 120-gallon ASME-certified horizontal tank provides ample air storage to reduce cycling and maintain steady pressure — perfect for production lines or multi-tool operations.

The R-70 Pump — Heavy-Duty Air Power for Industrial Applications

The R-70 is Champion’s large-displacement two-stage pump engineered for 20-30 HP compressors. Compared to the smaller R-40 pump, it features larger bores, improved airflow passages, and a low-speed design that maximizes efficiency and durability.

Benefits of the R-70 Pump:

• High output capacity (77.8 CFM @ 175 PSI)

• Low operating speed (664 RPM) for cooler running and reduced wear

• Heavy-duty cast-iron construction for longevity

• Oversized cooling fins and flywheel for efficient heat dissipation

• Reliable two-stage compression for maximum air pressure and efficiency

This combination of power and efficiency makes the HR20-12 ideal for continuous industrial use where performance and reliability are non-negotiable.
