Incorporating multiple sound absorbing technologies with the most powerful and efficient fans, ALDES kitchen systems always exceed expectations when it comes to performance.

Cape Backdraft Dampers

Dryer Vent Duct Accessories Dampers by American Aldes

American ALDES Cape Backdraft Dampers - 4" Backdraft damper. The Cape Backdraft Damper is designed to overcome the inefficiencies and limitations of traditional gravity or butterfly dampers. It incorporates a special fabric sleeve attached to the interior of a metal sleeve. The fabric sleeve will allow air to pass through in the desired direction of flow with minimal reduction in airflow.

features

• Minimal pressure loss in airflow direction. (Standard spring or gravity dampers offer more resistance to airflow and require higher opening pressures. At maximum opening, standard dampers have a smaller free area and create more turbulence, resulting in more static pressure loss and noise.)
• May be used in any orientation, other than for downward airflow
• Resists clogging by air-borne lint, making it an ideal damper for use with clothes dryer exhaust
• Silent operation
