Ingersoll Rand's rotary screw air compressors have a pedigree stretching back to the 1960s when the original IR electric driven rotary air compressors were created with the family name of "Pacair". Since that time, continuous research and development has produced generational changes; with the progressive advent of microprocessor control, variable speed drives, high efficiency two stage and oil free configurations, long life synthetic lubricants, energy-saving innovations including heat recovery kits, multiple control modes and constant pressure capability to name but a few.

Today’s machines have cast iron separator tanks, very little plumbing and even innovative high tech motors with dedicated variable speed controls, running cost calculators built in, computer aided maintenance like the latest cars, the ability to stop and start endlessly without damaging the motor or blowing down the compressed air system, built-in intelligence that enables them to run with other machines as a highly efficient module, single point maintenance access, longer periods between services, capacity increases available at the insertion of a pre-purchased electronic "key" and of course a number of extended warranty options.
