Radial Vane Dampers from Effox-Flextor-Mader (EFM) are used primarily on the inlet of centrifugal fans to direct flow and assist in pre-spinning the flow into the wheel. Radial Vanes are commonly referred to as Variable Inlet Vanes (VIV). The use of a radial vane damper enhances the performance of the fan by:
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.
