Photo of product family: Fire dampers with valve

The FDA-BU-KW / FDA-BU-KN coupling module is a combination of an air valve and a fire damper, coupled with a single housing. This is an alternative to typeical fire valves. The main advantages of the FDA-BU-KW / FDA-BU-KN are better fire rating and a smaller size with more product configurations and application options. The main component of the coupling module is the FDA-BU fire damper. The fire damper is available in Ø 100, 125, 160, and 200 mm. The wing blade of the damper provides a very low resistance to the air flow. The fire damper can be ordered with one or two optional limit switches to feed back the actual blade position.
