Product Description

American Aldes delivers the premier backdraft damper solution favored for residential, commercial and industrial installations around the world. The highly rated automatic backdraft damper provides a complete seal, with no leakage to prevent backdraft airflows. It has been designed for low pressure drop and to require almost zero pressure to open the damper flaps when air is flowing the correct direction. The entire assembly inserts into the ductwork for easy installation and prevent leakage. Available in 4", 5", 6", 7", 8", 10", 12", 14" and 16".

Installation

Backdraft dampers are simply fitted into the duct. The foam gasket provides a secure fit. 

Make sure the damper is oriented so that the damper blades are in the open position when the fan is on. The bades will close automatically when the fan stops.
