Shanghai Baosi Compressors Corporation Limited is a private company founded in March, 2005, which is specialized in designing and manufacturing of screw compressors using air power and technical process(including petroleum, coal seam gas). Its headquarter is located in Yuanmao Jinhao International mansion, Xikang Road in Shanghai. Now Baosi company have owned the manufacturing base as large as 120,000 square meters(first-stage).
Shanghai Baosi own a number of professional skill members engaged in design and production of process gas compressors. We import professional devices used for screw rotors and shell processing, in which the rotor slot milling machine of 5A, 3A, 2A are more than 10 sets, and the Mazak introduced from Japan used for shell fabrication are more than 10 sets.
Since Shanghai Baosi&rsquos inception, we have continuously invented the products on the screw compressors used for compress flew with independent enterprise intellectual property relying on our technological development ability and advanced processing equipments, including：
&bullFirst CBM screw compressor used for CBM pressurization in China
&bullFirst natural gas screw compressor used for production, pressurization and recollection of oilfield that can all-day control and operate by itself without manual operation in China .
&bull First natural gas screw compressor driven by the gas engine used for the low tension natural gas pressurization in China, that means the fuel of gas engine are from low tension gas in ground without external main power and water supply, as well as the cooling, lubrication and ignition control system of compressors.
&bullFirst pressurization and testing device used for low concentration methane CBM extracting in China.
&bullFirst CBM screw compressor used for suction and  pressurization of CBM in China.
