Economic operating cost.

The system adopts infinitely variable control Capacity adjustment within 0-100%. When the air consumption decreases, the Capacity and motor current will be reduced accordingly; when the air is not used, air compressor will run empty and stop automatically after long-time no-load running. When the air consumption is increased, the loaded operation is restored. Therefore, it has optimal energy conservation.

Good environmental suitability.

Designed with supernormal cooling system, it is particularly suitable for high temperature and humidity environment in Asia. Thanks to good vibration isolation technology and noise reduction measures, Kaishan screw air compressor is installed with no need for dedicated foundation, but minimum space for ventilation and maintenance only.

Design characteristics of screw rotor profile:

1. It fully realizes "Convex-Convex" engagement to assist in the formation of hydrodynamic lubrication film, to reduce horizontal leakage passing the contact zone, and to improve efficiency of the compressor; improve rotor processing and testing property.

2. It adopts the design thought of "large rotor, large bearing and low speed method", thus its revolving speed is 30-50% lower than that of other brands to reduce noise, vibration, and exhaust temperature, improve rotor rigidity, increase service life, and reduce sensibility to sundries and oil carbide.

3. Its power range is 4~355KW, where 18.5~250KW applies to the compressor without direct-coupled gearbox, 200KW and 250KW apply to the compressor with Level 4 direct-coupled motor and the speed is as low as 1480 rmp.

4. It fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Capacity Air Compressors.
