Nirvana - Rotary Screw Air Compressors

Variable Speed Drive.Contact-Cooled Rotary Screw Air Compressors

Rotary Screw Air Compressors

By matching a standard variable speed inverter with a HYBRID PERMANENT MAGNET® motor, Ingersoll Rand is first-to-market with a true variable speed drive compressors. In both single and two-stage, the Nirvana rotary screw air compressors has fewer rotating parts than any other air compressor in its class. And the Hybrid Permanent Magnet motor driving the Nirvana compressors 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 compressors, 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 Ingersoll Rand's time-proven, reliable airend, Nirvana is as low-maintenance as an air compressors can get.


  • Field-replaceable motor stator provides dramatically improved uptime
  • Integral design, fewer parts and fewer connections help eliminate trouble spots, leaks and failures
  • Time-proven quality airend and inverter
  • Maximum efficiency at virtually any load

Comparison of Rotary Capacity Controls

Nirvana rotary screw air compressors deliver constant pressure and maximum efficiency at any capacity.

The Nirvana motor turns off at 25% capacity and automatically turns on when air pressure decays

Nirvana rotary screw air compressors deliver constant pressure and maximum efficiency at any capacity.

Nirvana Two-Stage Beats the Performance of Any Other VFD Compressor at Full or Part Load

Rotary Screw Air Compressors
  • The typical compressors operates at an average of 70% load.
  • The Nirvana VSD decreases the overall energy cost 22% 30%, compared to a fixed speed rotary air compressors.
  • The Nirvana VSD decreases the overall energy cost 22% 30%, compared to a fixed speed rotary air compressor.
  • Maximum energy savings is achieved by the Nirvana two-stage yielding 33%-41% savings.

Rotary comparison at 70% average volume capacity; 4,000 hours per year; ,05/kWh Traditional purchase decision factors represent only 20% of the cost to own and operate a rotary screw compressors while energy represents 80% of the life cycle cost. Only nirvana will save at least 28% of the energy cost over its life. NIRVANA WILL REDUCE THE TOTAL LIFE CYCLE COST TO OWN AND OPERATE AN AIR COMPRESSORS
