Features

💡【Quality Material】The backdraft damper is made of galvanized steel, the flap leaves are made of aluminu, and the axis and spring are made of stainless steel, which can withstand temperatures up to 50°C. 💡【Practical Features】The air duct choke prevents cold air or wind from entering the ventilation duct. The backflow flap opens and closes automatically at low air volumes. The valve is equipped with a smooth-running spring and a rubber gasket that create an airtight seal and grip between the damper and ducts. 💡【Easy Installation 】The backflow prevention valve is installed by pushing it into the ventilation duct to make it as mobile as possible. When the valve flap is installed horizontally, the position of the spring should be horizontal so that the valve flap can be opened and closed optimally. This also applies to vertical installation. Same for vertical installation. 💡【Multiple Usages】The draft blocker is designed for use in AC, dryer vent, exhaust, extractor or range hoods, heating systems, fans, vents and other residential, commercial and industrial HVAC applications. The back draft damper can be inserted into a flexible or non-flexible ventilation duct. 💡【Needs Attention 】This airflow regulating backdraft shutter is installed on the TD lip to improve ventilation by preventing air circulation when the fan is not in use. Plastic pipes are of different sizes and cannot be used with plastic pipes.
