Champion HR7D-12 is a 7.5 HP two-stage splash-lubricated 100%-duty-cycle reciprocating air compressor in the Champion HR Duplex series, delivering 51.2 SCFM at 175 PSI on a 9-gallon receiver, wired for 230 V single-phase. Maximum operating pressure is 175 PSI. The HR7D is a duplex (twin-head) configuration, weighing 1,305 lb. MPN HR7D-12. Retail pricing is approximately $12,700.

The small 9-gallon tank reflects the expectation that duplex compressors feed dedicated system tanks. Gaps: no OEM Champion HR Duplex datasheet URL; no dB rating; voltage (230 V single-phase for duplex 7.5HP) needs OEM verification.
