Oil-Free Air Compressors
Oil-free air 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.
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.
