  1. #Description#
    BDD back draught dampers are manufactured using only the highest quality galvansed steel, with the gasket from polyurethane foam for low leakage. (RSK with gasket) 

    Specially  designed blades with closing spring insuring a tight seal.  This minimises back flow through the damper.

    Both ends on the BDD are manufactured small end so they all simply slot into spiral pipe.  

    BDD are also known as butterfly dampers, this is because there is a central sping that allows two blades to open.
