I’ve got two of these hooked up in the attic so I can run two exhaust fans to one outlook. They lit the air flow freely, but only in the direction I want. Allows me to pass code! Nice product, easy install and since it’s in the attic no perceived noise inside (I don’t know if it’s load next to it). Good value! Review: Tight seal and quality construction - I needed some sort of back draft prevention for my bathroom vent fan setup because I was getting bugs and draft in my basement bathroom. These fit right up to other 4 inch ducting, and I used rubber connectors to secure these on. They look sleek, work great, and they have a great quality seal and don't let air back in. They have a double flap to prevent back drafting. I used two of them in my set up to keep each line isolated before a combining y connection ## Features - An antidraft duct insert designed for use with range hoods, bathroom fans and other home HVAC applications. - Features outer rubber gaskets that create an airtight seal and grip between the damper and ducts. - Mounts horizontally or vertically to prevent backflow and debris from entering ducting. - Galvanized steel body with spring-loaded aluminum damper blades that open with minimal airflow. - Fit for 6 in.

Nicely made product at a fair price! *by S***E on April 8, 2026* The AC Infinity products I’ve been getting all seen to be superior quality pieces (fan, collars, dampers). Couldn’t be happier. Shutters open easily but close solidly when there’s no air flow. Thank you a great product at a fair price! ## Frequently Bought Together - AC Infinity 6" Backdraft Damper, One-Way Airflow Ducting Insert with Spring-Loaded Folding Blades for 6” Ducting in Range Hoods and Bathrooms Fans - AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity Noise Reduction Clamp 6-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/185858231-ac-infinity-backdraft-damper-for-6-ducting](https://www.desertcart.co.uk/products/185858231-ac-infinity-backdraft-damper-for-6-ducting) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-26*
