Below are some common questions and answers about the HMGB Magnetic Levitation Bearing Turbo Blowers from Shandong Huadong,

to help you understand performance, advantages, and whether it fits your application.

 

Q1: What is a Magnetic Levitation (Maglev) Bearing Turbo Blower, and how does it work?

 

The HMGB maglev blower integrates a magnetic levitation bearing, a high-speed permanent magnet synchronous motor, and a centrifugal impeller.

The rotor is suspended without mechanical contact, which reduces friction and wear.

Sensors monitor rotor position (vibration, space gap) and feed data to a control system.

The system adjusts electromagnetic force to keep the rotor aligned.

Air enters via an inlet, is pressurized by the impeller and expelled at required flow and pressure.

This structure gives smoother operation and less maintenance.

 

Q2: What are typical technical specs of the HMGB-55 model?

 

  • Pressure range: 30–50 kPa 

  • Capacity (flow): about 28–19 m³/min

  • Motor power: 55 kW

  • Noise level: below approx. 85 dBA 

  • Efficiency: up to ≈ 85 % for the blower unit; allows large turndown range; significant energy savings compared to traditional roots blowers

 

Q3: What advantages does HMGB maglev blower have over traditional Roots blowers?

 

Advantage

Details

Energy savings

Compared to a Roots blower input power of 150 kW, HMGB unit uses ≈ 75 kW for equivalent performance in some cases; annual saving in power consumption is very large. 

Smaller footprint

Maglev blower is more compact, less mechanical complexity (no large gears or oil lubrication systems) so space requirement is much smaller. 

Low noise

Below ≈ 85 dBA, due to reduced friction and well-balanced rotor. 

Wide turndown

HMGB models provide a large working range (turndown to ~87%) which helps handle variable duty cycles efficiently. 

 

Q4: Where are HMGB maglev blowers best applied?

 

These units are well-suited to industries requiring continuous operation, high reliability, and clean output. Key applications include:

  • Sewage / wastewater treatment for aeration systems 

  • Pharmaceutical / food processing where oil-free, low-noise air is needed

  • Textile, cement, power industries for boosting air or gas streams under pressure demands

 

Q5: What should you consider when choosing an HMGB maglev blower model?

 

  • Match your required flow and pressure from table of HMGB models (e.g. HMGB55, HMGB75, HMGB90, etc.) 

  • Check ambient temperature (recommended −10 °C to +45 °C) to ensure magnetic bearings work properly. 

  • Ensure power supply and variable frequency drive are compatible to benefit from full efficiency and control.

  • Evaluate noise restrictions and foundation or installation base since high-speed units need stable mounting.

 

Conclusion

The HMGB Magnetic Levitation Turbo Blower by Huadong offers an excellent upgrade path if you want a blower that is energy-efficient, low-maintenance, and compact.

For users who demand reliable performance with clean, quiet airflow, Airus HMGB models stand out.
