Its spring-loaded flap allows one-way airflow, preventing backdrafts and improving HVAC efficiency. Easy to install with a push-in design, it’s ideal for a wide range of applications including ACs, exhaust fans, and heating ducts, ensuring enhanced indoor comfort and energy savings. ## Description 【Installation】The backdraft damper is installed by pushing it into the ventilation pipe as far as it will go. The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation. 【Function】This airflow regulating backdraft shutter fits over the TD lip and is designed to improve ventilation by preventing air from re-circulating when the fans are not in use. Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different. 【Wide Application】 These backdraft dampers can be widely used in ACs, exhaust fans, extractors, range hoods, heating ducts, vents and other residential, commercial and industrial applications. Review: very good product - it works very well...no more cold air in my kitchen. Review: Function. Durability. Easy install. What most products should focus on - Wasnt avail at big box stores near me so I scrambled to order this for my contractor installing the ductwork for my new kitchen stove vent. He said it was perfect and easy to install. It seems to be working great and our city inspector specifically went out of his way to check it. Passed without issue.
