Gas is sucked into High Pressure Fan is from the gas inlet port then it enters the side channel. Under the high-speed rotation of the impeller, due to the centrifugal force, the gas is compressed by the vortex and finally it is discharged of the pump body in acceleration through the gas outlet port to achieve the raised intake gas pressure. Complete product models can meet the requirements of various specific applications. Any axial installation can be achieved to meet any space requirements and reduce installation costs. Motors(50/60hz) with wide voltage and double frequency are adopted; Clients’ needs all over the word can be met well.
