Champion HR7-12

Champion HR7-12 is a 7.5 HP two-stage splash-lubricated piston compressor with the cast-iron R-30 pump, mounted on a 120-gallon horizontal ASME tank and rated 25.6 SCFM at 175 PSI at 570 pump RPM. Champion’s R-Series Advantage line has been a workhorse of automotive and tire shops for decades; the slow 570 RPM pump speed is a real durability advantage that contributes to long pump life and low noise versus higher-RPM piston competitors. ACFM at lower setpoints is 28 at 125 PSI and 31.9 at 80 PSI. Standard package is 230/460V three-phase, with magnetic starter, automatic tank drain, low oil-level monitor, air-cooled aftercooler, and dual-control panel. Best for 3-5 bay auto shops, tire shops, body shops, fabrication facilities, and any application that needs 175 PSI service air without stepping up to a rotary screw. Champion (now part of Gardner Denver) backs the pump with a 5-year extended warranty when registered. Made in the USA.
