Butterfly Damper - Air Flow Control

Our 3800 butterfly damper works with both the insulated and uninsulated 4 way steel commercial ceiling grilles. Allow for complete air flow control with this damper which opens and closes with a removable handle. The butterfly damper comes in a 6, 8, 10, 12, 14 inch size and is round in shape. Air flow control is a good way to efficiently block air from escaping your vent when it is not needed. Install the butterfly damper on the 4 way ceiling grilles by simply sliding clips into place on the back collar of the grille. Keep the air flow control handle in place or remove it when not in use so as not to be seen by customers.
