Multistage centrifugal fan is a vertical split turbine compressor. Compared with traditional Roots fan and single-stage high-speed centrifugal fan, it has comprehensive cost-effective advantages in pressure, energy consumption, noise, reliability and investment cost. In recent years, with the improvement of international manufacturing technology, the improvement of design concept and the improvement of control technology, its advantages have been widely recognized, more and more used in all walks of life, is an economic and reliable power equipment.

Product characteristics：

It adopts the design and manufacturing technology synchronized with the international, and fully considers the pursuit of high pressure and high efficiency in the current application field in the design of the model. The efficiency of the impeller is as high as 92% and the efficiency of the main engine is as high as 80%.

Adopt high precision mold, aluminum alloy integrated casting, after precision machining and dynamic balance test to complete. Compared with the traditional welded impeller, it has the characteristics of light weight, high efficiency, uniform mass distribution, high dimensional accuracy and less manufacturing defects.

No power thin oil lubrication system, aluminum alloy air-cooled oil box, ensure continuous trouble-free operation, no oil pump, no cooling water, low maintenance cost.

The high pressure type fan outlet high pressure side bearing external standard cooling fan to ensure normal bearing temperature.

Medium and above models use balance plates to offset part of the axial force to ensure smooth rotor operation and extend bearing life.

The high-precision common base is used to carry the fan, the motor and all its accessories, which effectively ensures the coaxiality of the fan and the motor, and reduces vibration to a greater extent than the split base.

Intelligent control system monitors the running status of the fan in real time, adjusts the flow pressure on demand in time, and integrates anti-surge system to ensure safe and stable operation.
