Champion HR7F-12 – 7.5 HP 120-Gal 2-Stage Air Compressor

Champion HR7F-12 is a 7.5 HP two-stage piston air compressor delivering 25.6 SCFM at 175 PSI on a 120-gallon horizontal tank, wired for 230V single-phase, with a flywheel drive pump (HR7F designation). The two-stage cast-iron pump compresses air in two stages for improved volumetric efficiency and cooler discharge temperatures at 175 PSI. The 120-gallon horizontal receiver buffers demand spikes for sustained shop-floor operations — impact tools, air ratchets, spray guns, and die grinders. At 175 PSI rated output, this model meets pressure requirements of virtually all industrial pneumatic tools. Champion backs this line through its authorized service dealer network. Key gaps: motor RPM, decibel rating, weight, and OEM datasheet URL not in catalog; catalog shows 25.6 SCFM here vs 22.3 SCFM for other HR7F-12 entries — variant difference not yet confirmed.
