Variable Speed Drive Oil Free Rotary Screw Compressors
Only lngersoll Rand offers Nirvana Oil-Free, the world's first true variable speed oil-free compressor for critical oil-free applications requiring the highest quality of air and the greatest reliability available on the market. By matching an innovative modular variable speed inverter with a HYBRID PERMANENT MAGNET® motor, IR is again first-to-market, this time with a true variable-speed drive, oil-free air compressor.
The two-stage Nirvana Oil-Free compressor has fewer rotating parts than any other rotary air compressor in its class. And the Hybrid Permanent Magnet motor driving the Nirvana Oil-Free 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 pulleys, belts or couplings to wear out, leak or need replacing. And there is nothing to get out of alignment. Coupled with lR's time-proven, reliable two-stage oil-free airend, Nirvana Oil-Free is as reliable as an air compressor can get.
