What is the difference between HSS magnetic bearing turbo blower with other brands?

In my opinion, its the TEAM of HSS. 

HSS's core team is led by the winner of First Class Award of 2007 State Technological Invention Award. The team members come from well-known universities and aerospace research institutes of Tsinghua University, Beihang University and Chinese Academy of Sciences. 

CEO and CTO of HSS are the only combination who master the core technogy of magnetic bearing in magnetic bearing turbo blower, compressor and vacuum pump industry in China, and they are also the only combination that they are big shares holder around all the magnetic bearing technology companies of China. 

HSS is 100% technology-driven enterprise and HSS team leader don't position HSS as magnetic bearing turbo blower, compressor or vacuum pump developer, he position HSS as MAGNATIC BEARING SOLUTIONS. 

First Class Award of 2007 State Technological Invention Award is the highest awards in China.
