RADIAL VANE CONTROL DAMPERS
These are primarily intended as fan inlet control dampers where, by introducing swirl into the inlet of the fan in the direction of rotation, the fan curve is changed as the damper moves, thus maintaining operation at an efficient point on the fan curve and eliminating the possibility of stalling at low volumes.
The dampers can be designed to suit overhung impellers or impellers with through shafts and can be built for double inlet fans and operated by a single drive mechanism.
Materials of construction and drive configurations are selected and designed to suit the application and customer requirements.
