The magnetic suspension high-speed centrifugal blower developed and produced by Tianrui Heavy Industry is 100% contactless and frictionless, saving more than 30% power than the traditional blower. Its various technologies have a perfect combination of stability, reliability and efficiency.
Specifically, the optimized overall core technology (magnetic bearing, motor, impeller, others) provides stable and reliable operation. The centrifugal fan is an integrated structure, integrating the fan, PLC, VFD, MMI and other components.

Unique magnetic suspension bearing
- The rotor is suspended by electromagnetic force, and the bearing has no contact, no friction and no lubrication.
- Friction free rotation between bearing and shaft can greatly improve energy efficiency.
- Low noise, long service life.
- Real time signal acquisition and correction more than 10000 times per second to accurately control the rotor axis position.
Z durability, high speed motor
- 50000rpm ultra-high speed, efficiency of more than 97%, world-class.
- Simple design structure, suitable for various working environments, and durable operation.
Three dimensional flow backward curved impeller
- High strength aviation aluminum alloy
- Three dimensional flow backward bending design enables the fan to operate in a wide range of high efficiency, with an efficiency of more than 95%.
- 5-axis processing technology provides high-precision design scheme and excellent durability.
Efficient cooling system
- Efficient cooling system (air cooling/water cooling) is adopted without additional supporting equipment.
Advanced intelligent control technology
- Feixuan Maglev active control technology.
- international first-line brand frequency converter.
- An overall out of the box solution that saves preparation and installation time.
- The application of PLC control operation can meet the requirements of external environment changes more flexibly.
- Support multiple operation modes and communication protocols.
Z: maximized income
-The efficiency is more than 84%, and the life cycle does not reduce the efficiency.
-Energy saving of more than 30%, cost recovery in 2-3 years, and sustainable benefits.
-The noise is lower than 80dB, which can be installed and used in enterprises, parks, residential areas, hospitals and other environments.
-Integrated skid mounted structure, easy to install and basically maintenance free.
Conclusion:
Power saving, quiet, maintenance free, intelligent control.
The magnetic levitation blower of Tianrui heavy industry can effectively solve the problems of oil leakage, high noise, high electricity cost, high cost of maintenance and replacement of accessories and so on. To provide users with frictionless, oil-free, low-noise, low energy consumption green low-carbon environmental protection solutions.
