Permanent Magnet Industrial 8 bar Two Stage Screw Type Air Compressor Machines 30hp
Two-stage Compression Double Screw Air Compressor, screw rotor adopts a two-stage compression engine, is to use two groups of size is not consistent, reasonable distribution of pressure, lowering the pressure level at each level compression ratio. Reduce the leakage and improve the volumetric, reduce the bearing load, improve the bearing life, prolong the life of the host. The inlet of the main engine adopts the axial inlet, and the intake noise is reduced. Direct drive, high efficiency, low vibration and low noise.
