Non-return (backdraft) Dampers with Seals

Ventilation Ducting  | Dampers & Access Doors | Non-return Dampers |  Non-return (backdraft) Dampers with Seals



Lightweight aluminium blades on a light steel spring maintain the damper in the closed position when no air is flowing, preventing wind/drafts from flowing back through the duct. These dampers feature seals and rolled edges.
