Ingersoll Rand Rotary Screw air compressors are built around reliable, low-speed airends and motors that deliver more air for less horsepower. A whisper-quiet shaft-mounted centrifugal fan blower reduces power consumption and noise, simplifies ductwork, improves cooling and requires no maintenance. Ingersoll Rand Rotary Screw air compressors are ideal for waterborne paint applications where clean, quality air is essential. Models include the 5 to 15 hp (4 to 11 kW), the 15 to 50 hp (11 to 37 kW) and the Nirvana variable speed drive 7.5 to 40 hp (5.5 to 30 kW).
