6000V/10000V direct rotary screw air compressor

Direct drive screwcompressor: 1.Excellent powerful compressor airend; This air end is equipped with latest rotors with bigger diameter and low rotate speed,SKF overloading bearing and three stages special oil seals guarantees the air efficiency and the useful lifetime,and reduce the radial vibration and air noise. 2.Air coling model Highy engrgy-saving centrifugal cooling system. Special for powerful compressor(the consumption of electricity is only 7.5kw for 250kw-315kw models. 3.water cooling model High efficiency water-cooled cooler. The element of the cooler consists of the high efficiency finned copper tube and is combined wiht precise shell.This combination effectively improves the heat exchange rate between compressed air and water,reduces the consumption of the cooling water. 4.High efficiency motor Output efficiency is up to 96%, Degree of protection:IP23 or IP54, Service factor:SF=1.20, The special equipped SKF overloading bearing, Low noise and long useful lifetime.
