20 - 75 HP Rotary
Air or Water Cooled


Oil-free rotary screw compressors are used in a wide range of production and service facilities where clean air is required. The Kobelco KNW Series compressors meets the requirements of NFPA99 for use as a medical air compressor. A touchscreen display and the low sound level are ideal for applications where ambient noise poses operational difficulties.

25 - 500 HP Rotary
Variable Speed Drive


The integration of a variable speed drive into Kobelco's KNW Series standard air-cooled assembly promotes energy savings. Equipped with Allen-Bradley VFD, the lower system pressure reduces kW and leak load, and there are no current spikes at start up. The VFD energy savings result from operating at a lower unloaded kW and a shorter unloaded run time.

40 - 500 HP Rotary
Air or Water Cooled


The 2-stage design of Kobelco's oil-free compressors operating at pressures of 40–150 PSIG and capacities from 170–2400 SCFM are ideal for pharmaceutical, food processing, and semiconductor applications. The design delivers energy and cost savings through high efficiency rotors and anti-friction bearings for long life and smooth operation. Axial thrust is reduced by incorporating an air pressure operated thrust balance piston on each stage. This arrangement minimizes thrust loading thus increasing bearing life.
