 DM Series Permanent Magnet Variable Frequency Screw Compressor

Permanent magnet Direct Screw Air End

It is a unique new design, which combines the permanent magnet motor and the speed control frequency converter. It couples with the high quality air end, which shows the advanced screw compressor technology.

It can provide the unique energy-saving effect and super reliability. There is no motor bearing. The screwing compressor is driven by the permanent magnet motor. There is no consider about the attrition of the gear,pulley,belt, coupling,shaft seal and the moving parts, which leads to the leak or change parts. Meanwhile, it not need to consider the calibritionfor the gear coaxial seal. The high-effect converter technique will reduce the operating costs prodigiously, which can provide you a real excellent technology.
