Overview
The Champion L07RS Variable Speed Rotary Screw Air Compressor is a belt-driven, oil-injected single-stage compressor engineered for efficient, quiet operation in light industrial and commercial settings. Powered by a 10 HP / 7 kW TEFC motor with inverter drive, it delivers 42.9 ACFM at 110 PSIG with exceptional turndown capability, modulating from 100% to minimum load to match air demand precisely and save up to 25% energy. The precision-machined EK76 airend features 76mm rotors and achieves ISO 1217-certified performance across pressures from 110 to 190 PSIG. Operating at just 63 dB(A), the L07RS is ideal for noise-sensitive environments. Available in base-mount or plug-and-play AirStation configurations with 80, 120, or 240-gallon tanks and optional refrigerated dryers, this compressor combines advanced microprocessor controls, robust construction, and flexible installation options for reliable compressed air with minimal footprint and downtime.
