GUANGZHOU HAOZHI INDUSTRIAL CO., LTD.

1、High speed aerodynamic gas bearing：

The air dynamic pressure bearing developed by Haozhi hashigh stability, absolutely free of oil and grease,long service life, and the service life of starting and stopping is more than 200000 times.

2、High speed permane：

Haozhi has rich high-speed motor R & D and application cases.：the self-developed fuel cell centrifugal air compressor has a maximum speed of more than 120000 rpm, maximum rated power can be 30kW.

3、Efficient pneumatic system :

Haozhi has the ability to independently develop, manufacture and test the pneumatic system, and can reasonably select the schemes of single-stage compression,two-stage compression and turbine energy recovery according to the requirements of customers' fuel cell system, among which the turbine energy recovery scheme can save 10%-20% of power consumption.

4、High frequency driver :

Through independent R & D and customized development,Haozhi achieves the best matching effect between the compressor and the driver, and reduces the supporting cost of the compressor system to meet the performance and cost requirements of customers.

5、Precision manufacturing and testing:
