Turbine Blower

The air suspension high-speed centrifugal fan is directly driven by a high-speed Permanent Magnet Synchronous Motor (PMSM) connected with the impeller. The speed is precisely adjusted by a Variable Frequency Drive (VFD), with no gearbox or speed increaser structure.

The impeller is directly connected coaxially with the motor, and the shaft is supported by radial and thrust air suspension bearings.

As there is no mechanical contact and no lubrication system required during operation, the fan achieves high efficiency, low energy consumption, low noise, reliable operation and long service life.

The main unit is lubrication-free and maintenance-free; the system only requires regular inspection of filters and electrical components.
