Ingersoll Rand, a supplier of compressed air technology and vehicle service tools and equipment, said it has launched several new models in its rotary screw air compressor line. Models include the 5- to 15-HP, the 15- to 50-HP and the Nirvana variable-speed drive 7.5- to 40-HP rotary screw air compressors.

Nirvana rotary screw compressors have low power consumption at start-up, full-load and part-load conditions; delivering energy savings of up to 35% compared to competitive models, the company said. Component integration is enhanced by the IntelliDrive integrated variable-speed drive (VSD) power system. A simple firmware upgrade enables shops to add to their air capacity without having to upgrade to a new compressor, allowing the Nirvana compressor to grow along with a shop’s business, the manufacturer noted. The top-of-the-line Nirvana compressors deliver operating flexibility and a total air system (TAS) in one package, along with sound suppression as low as 65 dBA, the company added.

All the compressors are built around reliable, low-speed air-ends and motors that deliver more air for less horsepower, cutting energy costs and extending compressor lifespan, the company explained. Smart integration—with 70% fewer connections— the company said eliminates leaks and pressure drops, maximizing reliability. Air leaks are further prevented by using hydraulic type SAE O-ring fittings on all critical connections, Ingersoll Rand added.

All compressors are designed for easy operation and installation, with small footprints to help save space. The easy-to-use operator interface, convenient location of the service panel and easy access to internal components simplify maintenance and enable shops to install the unit close to a wall, the company said. Smart, energy-efficient controls eliminate wasteful unloaded running by quickly cycling the compressor off when not needed.

A quiet shaft-mounted centrifugal fan blower reduces power consumption and noise, simplifies ductwork, improves cooling and requires no maintenance, according to company. Quiet operation also allows the rotary screw air compressors to be installed closer to point-of-use, cutting costs and ensuring a better, safer work environment.
