The kernel of each screw air compressor lies in the bare compressor, and the screw is milled and grounded for high precision by state-of-the-art numerical control processing center. With the advanced technical process and high- quality materials and high-precision measuring method, each part is guaranteed for highest precision, and combined with fine grinding of screw profile and computer-based multi-step rotor control process, the rotor profile is guaranteed for 100% precision.
The compressors in ERC series rotates by means of triangular belts, coupling direct connection and gear change. The compressors are reasonably structured to ensure excellent operation and easy and correct installation, commissioning and maintenance, and it can also realize maximum rotational efficiency and longer useful life.
