The duct had feedback so we put this on to ensure the airflow was one way only and not flowing back into her dryer. IT was a perfect fit with the flexible duct tubing and the dryer. I did not need to bend or crimp anything. The flapper doors work very well and it’s a quality metal product. Very easy to install. So far it seems very durable. Great value for the money! Review: Best Inline Damper Ever! - Wow, this is beat my expectations. Works perfectly. Fits snug inside the duct. And its small size made a compromising situation that was very room to with, super easy! ## Features - Home Improvement: Especially suitable for inserting into dryer duct. Perfect for use in bathrooms, garages, sheds, campers, stopping inflow of air from AC units, range hood extractors, heating systems - Easy Installation: The duct damper opens and closes automatically, allowing only one-directional airflow. The damper blades open only in the outflowing air direction when the shutter is installed. The duct valve for 8-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation - Premium Material: The casing of the shutter is made of galvanized steel sheet. The dryer vent valve blades are made of aluminium. The shaft and spring are made of stainless steel - Great for Home Use: The inner rubber seal is used for better tightness and for noise reduction. The outer foam sealing strip provides good tightening and fixing of the backdraft damper inside the duct. The back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you must use steel duct clamps to secure the backdraft damper - Warm Prompt: Please note the diameter of this backdraft damper is 7.9" and it can be fit in a 8" diameter pipe or hole easily.

And its small size made a compromising situation that was very room to with, super easy! ### ⭐⭐⭐⭐⭐ Works for it's purpose *by M***J on June 14, 2025* We live in a very rural, windy area. Husband installed a vent for the microwave fan above our stove to vent outside. Any kind of wind had the vent making so much noise throughout the day Abe night. We finally got fed up with it and purchased this... it was extremely easy for him to install and sealed great! We no longer hear the extremely loud, annoying flapping and it has stopped so much backdraft. The fan ventilation system is even quieter than it was before! We've had it installed for over a month now with some pretty nasty storms and seems durable! ## Frequently Bought Together - FRESH SPEED 8-Inch Backdraft Damper Shutter Inline Spring Loaded for Dryer Duct - Hon&Guan 8'' Soffit Vent Cover, Round Vent for Bathroom & Home (200mm) - AC Infinity Flexible 8-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/527722787-fresh-speed-8-inch-backdraft-damper-shutter-inline-spring-loaded](https://www.desertcart.com.om/products/527722787-fresh-speed-8-inch-backdraft-damper-shutter-inline-spring-loaded) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-05-17*
