High Quality Direct-Driven Vacuum Pump (BSV10: 0.4KW)

In 2005, the Yi'nuo Baosi Group invested in founding Shanghai Baosi Compressor Co., Ltd. In Shanghai. The company engaged in the famous screw compressor design with manufacturing experts, enjoying the subsidies of the State Council for the first batch of screw studies and design engineers. After 4 years of research and development, we succeedd in mastering the unique BAOSI technology and design for the BAOSI screw rotor, which has independent intellectual property rights.

In May of 2008, the Yi'nuo Baosi Group invested in setting up Ningbo Baosi Energy Equipment Co., Ltd., which formally put the brand into large-scale production, with the steady development of the energy equipment industry and a growing technical team in July of 2009. So far, the company has formed a series of products including screw compressor air end/hosts, medium-pressure screw compressors, screw vacuum pumps, oil-gas multiphase pumps, skid-mounted liquefaction equipment, flammable gases (CBM, oil gas, petrochemical exhaust, biogas, shale gas and other industrial gases), and recycling engineering equipment.

The group now has assets totalling over 500 million RMB, 1800 staffs and 173, 333 m2 factory and office area, as well as more than 50 units of Japanese Mazak machining centers, more than 50 sets of screw rotor machines, 4 sets of German KAPP grinding machines, etc. Annual production reaches 60, 000 units of screw compressor air ends, 5000 sets of screw air compressors, and nearly 200 sets of industrial gas compressors. In regard to protection of intellectual property rights, we have applied for 39 domestic and abroad patents, 17 of which has been authorized, including 2 invention patents, 6 appearance design patents, and 9 utility model patents.
