Ingersoll Rand Nirvana VSD Oil-Free Rotary Screw Air Compressors 37-45 kW

Ingersoll Rand Nirvana oil-free rotary screw compressors pair a matching variable speed inverter with a hybrid permanent magnet (HPM) motor for efficiency at all speeds, delivering 100% oil-free air certified to ISO 8573-1 Class 0. The 37 and 45 kW models deliver up to 6.71 m³/min, with no motor bearings, pulleys, belts, couplings or motor shaft seals to wear out.

The Ingersoll Rand Nirvana is a variable speed oil-free rotary screw air compressor that delivers 100% oil-free compressed air certified to ISO 8573-1 Class 0, for critical applications in food and beverage, pharmaceutical, textile and electronics processes. A variable speed inverter is matched to Ingersoll Rand’s hybrid permanent magnet (HPM) motor, which keeps efficiency high across the speed range, allows wide turndown and virtually unlimited starts and stops. The HPM drive has no motor bearings, pulleys, belts, couplings or motor shaft seals to wear out, leak or need replacing.

The 37 to 45 kW range covers two models: the IRN50H-OF (37 kW) delivering 5.66 m³/min at 7 bar and 5.07 m³/min at 8.5 bar, and the IRN60H-OF (45 kW) delivering 6.71 m³/min at 7 bar and 6.20 m³/min at 8.5 bar. Stainless steel components, dual-vented seals and precision-machined rotors with UltraCoat protection are built for reliability, Ultra Coolant runs up to 8,000 hours between changes, and the compressors are designed for ambient temperatures up to 46 °C. Both models are available air-cooled or water-cooled, are controlled by the Xe-Series controller with a colour display and remote access, and measure 2,080 × 1,120 × 2,070 mm. For larger sites see the Nirvana 55-75 kW. For fixed speed oil-free compressors up to 75 kW, see the Ingersoll Rand Sierra, and pair either with desiccant air dryers.
