Description
  • Antidraft duct insert: This item is designed for use with range hoods, bathroom fans, and other home HVAC applications. It features outer rubber gaskets that create an airtight seal and grip between the damper and ducts.

  • Mounting options: The product mounts horizontally or vertically to prevent backflow and debris from entering the ducting. It is made of galvanized steel with spring-loaded aluminum damper blades that open with minimal airflow.

  • Size and Finish: This damper is suitable for 4 in. duct openings. The overall product length is 5.03 inches and it features a powder coat finish.

  • Product Description: This ventilation ducting tool, designed for insertion into 4” ducting, prevents cold drafts and debris from flowing into ventilation systems. Built to be embedded in ducts, it made of sturdy galvanized steel and features two rings of outer rubber gaskets that enable an airtight seal in either a horizontal or vertical orientation. The damper blades, made of aluminum, are equipped with a light spring that folds with minimal airflow.

  • Applications: The spring-loaded antidraft damper is built for heavy-duty performance in applications such as overhead range hoods in kitchens, bathroom fans, and tumble dryers. It can be fully or partially inserted into your duct work using the rubber rings to hold itself in place. Other potential applications include maintaining pilot lights in water heaters and preventing debris from entering inline duct fans in enclosed spaces.

    High quality, tone down the damper strength

    This product appears to be of high quality; however, my 4 inch fan seems to struggle opening up the damper blades especially on the lower air flow settings. May end up removing it from the duct work and just rely on the outside vent cover to prevent backflow.

    The 4 inch backdraft damper is a quality product and is well packed for shipping from AC infinity. One improvement would be to reduce the number of spring windings by one or two that control the damper blades. The 4 inch motor has to work too hard to open the damper compared to the 6 inch setup. Otherwise it is a great product!
