Backdraft Prevention

By incorporating spring-loaded blades, backdraft dampers ensure that airflow only moves in one direction, effectively preventing the backflow of air into the system.

Robust Construction

The use of 24GA, G90 galvanized sheet metal ensures durability and resistance to corrosion. This makes them suitable for long-term use in various environments.

Rubber Gasket

The rubber gasket prevents air from leaking through the damper when closed.

Bulk Pack

The bulk packs offer convenience for contractors or other professionals who require multiple dampers for their projects.
