Product Details
30 hp 3 phase electric oil-injected rotary screw drive stationary double screw air compressor
KAISHAN LG oil-lubricated rotary Screw Compressor adopts 0~100% infinitely variable control of Capacity to realize optimal energy saving effect.
- Design Characteristics of Screw Rotor Profile:
- 1. It fully realizes “Convex to 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.

Why use a rotary screw air compressor?
Rotary screw air compressors are popular in factories, plants, or any manufacturing facility due to the cycle on which it runs. Whereas other types of air compressors can only work for on/off cycles, rotary screw compressors run non-stop around the clock. These rotary compressors actually work best when you leave them on 24/7. With a 100% duty cycle, rotary screw air compressors should not be shut off and started back up on a recurrent basis.
As long as a screw-type air compressor is sized correctly, its efficiency is superior to most other air compressors. While this does depend on the design of a particular brand of the compressor, the best models on the market help factories maximize efficiency across the chain of production.

In 2005, cooperating with Xi'an Jiaotong University compressor
research institute and interlinking with the state 863 project, the
group successfully developed a high-tech product: screw air
compressor's core part : screw rotors . It marks the end of relying
on import this unit from overseas only in China. The success has
made Kaishan group the first in the industry which owns the
intellectual property, core technique and competitive advantage
among large-scale equipment manufacturers in China. In 2006,

a large-scale and diversified manufacturer with its own patent core
technique and core competitiveness. We are striving to rejuvenate
our national industry and develop as the pillar of Chinese air
compressor industry in a yearning for greater contribution to
China's harmonious society construction and national equipment
manufacturing industry development.
