Description
Champion HR7D-12 Air Compressor – 7.5 HP R-Series Duplex Industrial Air Compressor (120 Gallon)
The Champion HR7D-12 Air Compressor is a heavy-duty R-Series duplex reciprocating air compressor system designed for automotive shops, light manufacturing, maintenance facilities, and industrial workshops requiring reliable compressed air with built-in redundancy. It features two 7.5 HP three-phase electric motors (15 HP total system power), dual Champion R-Series R-30 two-stage cast iron compressor pumps, and a 120-gallon ASME-certified horizontal air receiver tank.
Engineered for continuous-duty industrial performance, the HR7D-12 provides stable airflow and long service life through Champion’s proven splash-lubricated R-Series pump design, which operates at low RPM for improved cooling, reduced wear, and high durability.
This system delivers approximately 51.2–51.6 CFM at 175 PSI, making it suitable for multiple pneumatic tools and medium-sized production environments.
