Round Industrial Control Dampers

Round dampers for industrial control applications using a variety of materials and actuators.

The industrial round control dampers have solid flanges welded around the circular frame, providing a rigid base to support the butterfly-style blades. These are rated up to 30 in. wg static pressure and velocities up to 7000 fpm.
