Variable Pitch Axial Flow Fans

Turbomachinery for Green Society

World Largest Class Variable Pitch Axial Flow Fan(10,000kW)
World Largest Class Variable Pitch Axial Flow Fan(10,000kW)

The first MHI variable pitch axial flow fan was developed as a forced draft fan for a thermal power plant in 1965. MHI has provided more than 500 axial fans since then.

MHI axial fans are operating in various fields such as thermal power plants, desulphurization facilities, blast furnaces, sintering furnaces, ventilation of tunnels, etc.

Main Features

Wide Lineup

  • MHI has a wide lineup of axial flow fans ranging from low pressure, high flow rate to high pressure, low flow rate. Customers can find the best product that fits their specification.

High Reliability and Quality

  • The reliability of MHI fans is achieved with wide experience and the latest technology.

Compact Size

  • High-flow-rate design based on CFD (computational fluid dynamics)
  • Performance confirmation by scale model tests and actual tests

Flexibility of Installation

  • The rotor is small and light, which leads to significant reduction in foundation construction cost.
  • MHI axial fans are adaptable to various installation means such as horizontal, vertical, on steel construction, intake-side drive, outlet-side drive, etc.

Low-Vibration

  • Safety design allows operating speed to have a sufficient margin to the critical speed.
  • Anti friction bearings with original damper structure contribute to low vibration of shaft systems.
  • Strict shop balancing limits vibration of each fan at the minimum level.
