EM-11 : Extruded Backdraft Damper, Horizontal Mount
Model EM-11 is a horizontally mounted aluminum backdraft damper designed to permit vertical upward airflow while preventing reverse (downward) flow when the fan is off. The blades open under system pressure differential and close by gravity, delivering reliable, power-free backdraft protection. A discharge-side flange provides secure attachment, and adjustable counterbalance weights assist blade opening.
