Premium 6 Inch Back Draft Damper - High-Quality HVAC Ventilation for Fireplaces, Dryers & Exhaust Systems

Product Description

Tamarack’s Cape Backdraft Damper features a specially formulated fabric sleeve attached to a 6" outer metal sleeve that enables maximum air flow in the desired direction and closes with minimal pressure in the opposite direction. 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 Tamarack Cape Backdraft Damper is a non-mechanical in-line one way air flow valve that requires minimal pressure to open or close. Tested to UL 723 and NFPA 255 standards. This non-restrictive damper fits inside the duct.
