Nirvana runs at 95 percent efficiency throughout its entire speed range. 2.Exceptional Reliability: Nirvana has fewer rotating parts than any other compressor in its class. The HPM motor uses no bearings and directly drives the compressor, eliminating gears, pulleys, belts, couplings and motor shaft seals. 3.Transcendent Technology: Nirvana's exclusive Hybrid Permanent Magnet motor has revolutionized compressor performance by providing more air over a wider range with no increase in power consumption.
