Champion HR7D-24

Champion HR7D-24 is a 7.5 HP duplex two-stage reciprocating industrial air compressor delivering 51 SCFM at 175 PSI maximum pressure on a 240-gallon horizontal ASME tank. The duplex configuration pairs two R-Series cast-iron pumps for near-continuous duty and built-in redundancy, wired for 230V single-phase. Unit weight is 1,675 lbs at a verified list price of $14,793. The dual-pump architecture suits body shops, production cells, and fabrication floors where one pump can service while the other runs. Remaining gaps: duty cycle percentage and individual pump CFM ratings not available in current data; OEM datasheet URL unconfirmed.
