This document provides information about an oil-free screw compressor series that has improved performance over previous models through a two-stage compressor design and reduced internal piping pressure loss. Key features include an oil-free rotor chamber design that introduces no oil, stainless steel shaft seals to prevent carbon dust generation, and twin atmospheric shaft vents to prevent oil from entering during unload operation. Technical specifications for air-cooled and water-cooled models are provided.

1. OIL-FREE SCREW COMPRESSOR
Performanceof this serieshas g
than that of previous models. This has been achieved hy adopting
a two-stagecompressorwith good Specific Power Consumption (kW/m3/min),
cing the pressureloss of the internal piping.
Providing the ultimate in clean air...........
The oil-free design introduces absolutely no oil to the rotor
chamber in process. Stainlesssteel shaft-sealrings are used to
prevent the generation of carbon dust. and Kobelco's patentt
twin atmospheric shaft vents prevent lubricating oil from
unloadoperation.
