一、Features: 
1. Stainless steel material, reliable sealing element, integrated double-end mechanical seal are adopted, so achieve zero leakage when pressure feeding gas.
2. The gas containing a large amount of water vapor and small particles can be aspirated and the gas which is soluble in water or not easily in contact with water can be compressed when other liquids are used as working fluid.
3. The parts which can be supplied in unit are as follow: electric control system, gas-liquid separator, heat exchanger, condenser, etc., which constitute a complete unit, automatically monitored and controlled automatically.
4. In terms of compressor performance, it can completely replace similar foreign products.
5. There are two types of structures: single and double stage.
