Kobelco Family of Oil-Less Recipricating Air CompressorsOil-Free Rotary Screw Compressors

High-Quality, Quiet and Energy Efficient

The Kobelco KNW Series assembly is designed and constructed to exacting quality standards. These standards result in assemblies with long operating life, minimum maintenance and low operating costs.

The Kobelco KNW Series oil-free rotary screw air compressor is designed, manufactured, assembled, and tested in the United States and is delivered ready for operation. The two-stage 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, which is acknowledged to be the most efficient, twostage, 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. The efficiency is further enhanced by a unique load/unload control system that is simple and trouble free.

The compressor air end is a heavy-duty, two-stage design with each stage driven by a common gear. These components are arranged in a single modular design to form a compact unit which is mounted on vibration isolators to a structural steel base. No special foundation considerations are required.
