Rogers KNW Series

The Rogers KNW Series oil-free rotary screw air compressor — which is designed and built to the highest standards, resulting in minimal maintenance, long operating life, and low operating costs — provides either 20-50 or 40-500 HP. Because no oil is allowed in the compression chambers, the two-stage rotary screw compressor is able to provide completely oil-free compressed air. The Rogers KNW Series employs a new patented Super Rotor design for both compression stages.

This Super Rotor design is why the Rogers KNW Series is widely accepted as the most efficient two-stage, oil-free rotary screw air compressor on the market — not to mention that this novel new asymmetric rotor profile has the lowest power consumption per cubic foot of compressed air. And the Rogers KNW Series' unique and easy-to-use load/unload control system further enhances its efficiency.

The Rogers KNW Series' compressor air end is a heavy-duty, two-stage design in which both stages are driven by a common gear. The compressor components are arranged in a single modular design, forming a surprisingly compact unit that is then mounted on vibration isolators to a structural steel base (no special foundation required).

The Rogers KNW Series features precision-machined timing gears, which are mounted on each rotor shaft in order to maintain accurate clearances between rotors. To ensure long operating life and smooth operation, the bearings are anti-friction type, and the electric motor is directly coupled to the input drive shaft by way of a flexible coupling.

In order to reduce axial thrust, an air pressure-operated thrust balance piston is incorporated at each stage, minimizing thrust loading and further improving bearing life. The programmable microprocessor controller is a state-of-the-art design that maximizes operating efficiency and versatility. The Rogers KNW Series operates quietly thanks to its sound-attenuated enclosure, and the doors and hinged and pinned for easy removal.
