Outstanding performance
A new generation of bilateral asymmetric screw rotor profile, polishing process, high efficiency, low noise. Base on the design of the 3D cavity body and the flow channel, the flow resistance is small. Special thrust bearing for compressor, high precision and long lifetime. Crane mechanical seal, reliable and durable. Efficient oil and gas processor, exhaust oil content is not more than 5ppm.
