Variable-Speed Drive, Oil-Free Rotary Screw Air Compressors

1 Variable-Speed drive , Oil-FreeRotary Screw Air CompressorsOIL- free NIRVANA Oil-Free . ATRUE variable speed drive Oil-Free AIR COMPRESSOROnly Ingersoll-Rand offers Nirvana Oil-Free , the world s first true variable speed oil-freecompressor for critical Oil-Free applications requiring the highest quality of air and the greatestreliability. The two-stage Nirvana Oil-Free compressor offers:nFewer rotating parts than any other Rotary air compressor in its Permanent Magnet (HPM) motor has no bearings, thus raising the standard oncompressor reliability to an unequalled pulleys, belts or couplings to wear out or need replacing the HPM motor directly drivesthe s time-proven, reliable two-stage Oil-Free MOTOR STATOR PROVIDES DRAMATICALLY IMPROVED UPTIMEN irvana Oil-Free s high-efficiency HPM motor has virtually no wearing parts.

2 Should the motor besubjected to a catastrophic electrical surge or other electro-thermal event that damages one ormore of the motor coils, the stator is quickly and easily replaced in the field by authorizedtechnicians. The Nirvana stator exchange program provides: nQuick, convenient expense than a motor RELIABILITYTHE REVOLUTIONARYHYBRID PERMANENT MAGNETMOTOR HAS NO BEARINGS AND VIRTUALLY NOWEARING Oil-Free 'S INTEGRAL DESIGN, PATENTEDPACKAGING AND HPM MOTOR ELIMINATE TROUBLESPOTS, EFFICIENCY LOSS AND FAILURE. TIME-PROVEN QUALITY AIREND Not everything in the Nirvana Oil-Free compressor is brand new.

3 At the core of every NirvanaOil- free compressor is IR s rugged, reliable, two-stage Oil-Free airend. Used in thousands ofcompressors worldwide, IR s advanced Oil-Free airend features:nUnmatched rotor profile accuracy and repeatability. The airend is precision-machined in atwenty-step manufacturing coated with UltraCoat the most durable rotor coating PERFORMANCEULTRACOAT. SOLVING THE NEED FOR BETTER Oil-Free PERFORMANCE AND ENERGY SAVINGSThe challenge: to give our customers an Oil-Free Rotary compressor that operates at peakperformance throughout its lifetime. With the introduction of our fixed speed Oil-Free compressor ,Sierra, we introduced has proven to be unmatched in its protects every Sierra airend and now every Nirvana Oil-Free airend.

OUR CUSTOMERS GET MAXIMUMCAPACITY AND LOWER ENERGY COSTS OVER A LONGER AIREND LIFE 555115 F/46 C AMBIENT RATED PACKAGE FOR LONGER RUNNINGPERFORMANCEN irvana Oil-Free compressor is rated for 115 F/46 C throughout the entire package.

5 This meansthat the motor, coolant, electrics, controller and cooler design are rated for high ambientconditions. This increases performance by allowing fewer nuisance and electrics aredesigned to handle the highambients which can causecontroller failures if not properlydesigned. nMOTORMany compressor manufacturerswill simply put a high ambientmotor on their package and claimthat it s rated for highertemperatures. In the Nirvana Oil-Free , high ambient operationapplies not only to the compressormotor, but to the entire means that the motor,coolant, electrics, controller andcooler design are rated for highambient Nirvana Oil-Free cooler designprevents nuisance shutdownscaused by fouled coolant utilized in a Nirvana Oil-Freecompressor is also rated for 115 F/46 Cambient so that its properties do notbreakdown and cause EFFICIENCYNIRVANA WILL REDUCE THE TOTAL LIFE CYCLE COST TO OWN ANDOPERATE AN AIR COMPRESSORIR s exclusive VSD provides unequalled energy efficiency.
