Kobelco products are known for their long operating life, minimum maintenance, and low operating costs. The two-stage, oil-free, rotary screw compressor provides completely oil-free air because no oil is allowed in the compression chambers. Both compression stages employ a new patented Super Rotor design, known to be the most efficient, two-stage, oil-free rotary screw air compressor on the market. This new asymmetric rotor profile provides the lowest power consumption per cubic foot of compressed air.
