Variable Speed Drive Contact Cooled Rotary Screw Compressors
By matching a standard variable speed inverter with a HYBRID PERMANENT MAGNET® motor, IR is first-to-market with a true variable speed drive compressor. In both single and two-stage, the Nirvana compressor has fewer rotating parts than any other air compressor in its class. And the Hybrid Permanent Magnet motor driving the Nirvana compressor raises the standard on compressor reliability to an unequaled level.
There are no motor bearings in the HPM® motor. And since the HPM motor directly drives the compressor, there are no gears, pulleys, belts,
couplings or motor shaft seals to wear out, leak or need replacing. And there is nothing to get out of alignment. Coupled with IR's time-proven, reliable airend, Nirvana is as low- maintenance as an air compressor can get.
