Radial Vane Dampers

Radial Vane Dampers are designed with multiple blades around a center hub. This introduces swirl into the fan inlet, providing an efficient method of control and enhancing performance. Effox-Flextor brand Radial Vane Dampers utilize this design to change the fan curve as the damper moves, thereby eliminating low-volume stalling of the fan for increased fan performance.

Our Radial Vane Dampers are configured to deliver optimal performance, efficiency and durability, while maintaining low operating costs. With heavy-duty and self-supporting blades, requirements for any bearings or supports in the gas stream are eliminated, also enhancing fan performance.


  • Low Total Cost of Ownership
  • Smooth and reliable operation with multi-turn actuators
  • Premium quality construction materials for long life value


  • Cantilevered blade design with dual outboard bearings
