C-Power CPM Oil-Cooled Permanent Magnetic Variable Speed Screw Air Compressors offer high performance at a cost-effective price range. They come equipped with a new generation airend (EU-COMP) that minimizes the backflow of compressed air for higher overall efficiency. Large rotor and low speed design lead to less vibration, less noise and longer service life. High precision bearings and high quality shaft seals ensure low leakage, IE5/IP65 high efficiency oil-cooled permanent magnet synchronous motor ensures uniform cooling, no degaussing, long service life and reliable energy savings.
