The running costs of the economy 
 0-100% of the displacement steplessly. When the gas consumption is reduced, the displacement decreases, followed by motor current is also reduced; without gas, air compressor, empty running, empty for a long time automatically shut down. Gas consumption increases, the recovery of heavy vehicles. Energy-saving effect is optimal. 
 Good environmental adaptability 
 Extraordinary cooling system design, especially for the Asian high-temperature, high humidity environment. Excellent vibration isolation and noise reduction measures, so that the installation of the mountains brand screw compressor without a dedicated basis, only to set aside a minimum ventilation and maintenance of space, you can settle your compressor. 
 Screw rotor profile design features: 
 First, the full realization of the curved face of the Surface meshing, thus contributing to the formation of a hydrodynamic lubrication film, reducing the contact zone of the lateral leakage, improve compressor efficiency; as well as to improve the processing, test performance of the rotor. 
 Two, using the design ideas of the greater trochanter bearing, low-speed ", speed 30 ~ 50% lower than other brands, can reduce noise and vibration, reducing the exhaust temperature and improve the rigid rotor and prolong life, reduce the impurity and the sensitivity of the oil carbide. 
 Third, the power range of 4 ~ 355KW, of which 18.5 ~ 250KW are Direct more 200KW and 250KW 4 pole motor Direct gear box, speed as low as 1480 r / min. 
 Four, fully meet or exceed the national standard GB19153-2003 "air compressors energy efficiency limit value.
