Fox Equipment - Radial Vane / VIV / IVC Dampers

Radial Vane /VIV /IVC Dampers provide additional flow control for fan inlets. Radial Vanes also provide pre-spin of the air into the fan. Starting the fan while the damper is in the closed position allows for a low horsepower startup. Fox Equipment supplies all radial vane dampers with a cantilevered blade design complete with two external bearings thus eliminating the need for blade support and bearings in the gas stream. Fox Equipment also has a cantilevered conical design for FD fan applications.
