Dual R-70 Pumps for Continuous-Duty Industrial Power

The Champion HR20D-24 is a duplex industrial-duty air compressor designed for facilities that require massive air capacity, built-in redundancy, and continuous operation.
Equipped with two R-70 cast-iron two-stage pumps, each powered by its own 20 HP motor, this unit produces a combined 155.6 CFM @ 175 PSI — providing high output with exceptional efficiency and reliability.

The 240-gallon ASME-certified horizontal tank ensures steady air supply and reduced cycling, while the duplex control system allows alternating operation between pumps for balanced run time or simultaneous operation during peak demand.

Dual R-70 Pumps — Power, Redundancy, and Reliability

Champion’s R-70 pump is a proven industrial performer, combining low-RPM operation with high efficiency.
In a duplex configuration, two R-70 pumps provide double the output while maintaining cool, quiet, and dependable operation.

Duplex System Advantages:

• Massive Air Output: 155.6 CFM @ 175 PSI total

• Automatic Alternation: Balances pump runtime for longer system life

• Peak-Demand Capability: Both pumps can run simultaneously when needed

• Built-In Redundancy: Ensures continuous air supply even if one side requires maintenance

• Low-RPM Design: Each pump operates at just 664 RPM for cooler, quieter operation

The HR20D-24 is built to handle the toughest industrial applications — keeping your operation running smoothly without interruption.
