Advanced Compression Module
Decades of oil-free rotary compressor experience have taught us how vital the rotor/housing coating is to initial and lasting compressor performance. As a result, "Ultracoat" was designed specifically for this oil-free compressor application, with its unmatched adhesion, durability, and temperature resistance properties the key selection criteria. Combining the Ultracoat process with stainless steel module components, provides the customer with optimum long term compressor performance. In short, this means more compressed air for the operating cost dollar. -
Design Excellence
The Nirvana Oil-Free package features were designed for optimum customer benefit. The 115° F ambient rating lessens the chance for nuisance shutdowns due to summer heat or dirty coolers. The package air flow materials of construction, stainless steel for cold-side piping, aluminum for the moisture separators, and the non-corrosive compression module components add to the compressor's operating life and insure the delivery of clean compressed air. -
Design Flexibility
With Nirvana Oil-Free, the choice is yours for an air or water-cooled package. Both have been designed for optimum performance and industry leading application range (65-150 psig). -
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. -
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.
