Champion HR7-24 is a 7.5 HP two-stage reciprocating piston air compressor delivering 25.6 SCFM at 175 PSI on a 240-gallon horizontal tank, wired for 208V single-phase. Oil-free lubrication eliminates contamination risk, making it suitable for food processing, pharmaceuticals, and any application demanding clean, dry air. ASME-certified tank and Made-in-USA construction. Motor turns at 1,750 RPM; air outlet is 1-inch NPT. At 1,236 lbs and simplex configuration, this unit targets permanent installations in medium industrial shops requiring sustained output at high pressure without oil carryover. Priced around $7,382 (verified May 2026). Key gaps: duty cycle rating and noise level (dB) not confirmed from primary sources.
