The Cape Backdraft Damper is the ultimate one
way air flow valve, designed to overcome the inefficiencies and limitations of
traditional gravity or butterfly dampers.
The Cape Damper consists of a specially formulated fabric sleeve attached to an
outer metal sleeve. The fabric sleeve will allow air to pass through in the
desired direction of flow with miniscule reduction in airflow. For reverse
airflow, airflow that should be stopped by a backdraft damper, the Cape Damper
gives a better seal at a lower pressure and holds that seal as the pressure
increases. The Cape Damper is quiet, with no metal clanging sounds, and can be
installed in a horizontal or vertical orientation. It is available in two sizes,
4" and 6".
Best installed horizontal position. |
