Ingersoll Rand 2475N7.5

Ingersoll Rand 2475N7.5 is a 7.5 HP two-stage splash-lubricated piston compressor with the legendary Type 30 cast-iron pump, rated 24 SCFM at 175 PSI on an 80-gallon vertical ASME tank. The Type 30 platform has been an industrial standard for decades; this generation features individually cast cylinders, an overhung crankshaft, automotive-style two-piece connecting rods, and balanced pistons that reduce vibration and extend pump life. Ingersoll Rand publishes a pump-life expectation of more than 15,000 hours of trouble-free use. The Premium Package (P suffix) adds an air-cooled aftercooler, automatic tank drain, low oil-level shutdown switch, and high-efficiency intake filter with sound attenuation baffles. Standard package is 230V single-phase; three-phase 460V variant is also available. Best for 2-bay auto shops, body shops, woodshops, fabrication and weld shops needing a long-life 7.5 HP industrial piston without three-phase. Ingersoll Rand backs the pump with multi-year warranty when registered. Made in the USA.
