This immediately stopped any condensation inside the dryer thankfully! It was easy to install and took about 5 minutes- we attached it to the dryer hose with zip ties. Once installed I haven’t noticed any condensation on the dryer door or inside the dryer! The only thing I’m concerned about is eventually needing to removed it to check for lint build up around the ‘door’ that opens and closes but even if there is lint I’m happy there’s no more moisture inside the dryer Review: Size - It does not needs to be cramped to fit a 6 inch pipe ## Features - 【Product Contain】Package includes two backdraft damper with diameter of 6 inch/ 150mm.

This immediately stopped any condensation inside the dryer thankfully! It was easy to install and took about 5 minutes- we attached it to the dryer hose with zip ties.

Works great! *by J***N on January 23, 2026* Perfect for my installation. Too many of these type dampers have very stiff springs and it will not work with low CFM air flows. These are great. You can blow at them with your mouth and get them to open. And they seal very well. I use them for air circulation between rooms with fans set to about 60 CFM. The last ones I got restricted about 80% of the air. These only restrict maybe 10%. This is key for low CFM situations like bath exhaust fans, for instance. ## Frequently Bought Together - 2 Pcs 6 Inch Draft Blocker Backdraft Damper Duct Draft Stopper One-Way Airflow Ducting Insert Backflow Preventer Inline Fan Vent Deflector - AC Infinity Flexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust --- ## 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.be/products/522100013-2-pcs-6-inch-draft-blocker-backdraft-damper-duct-draft](https://www.desertcart.be/products/522100013-2-pcs-6-inch-draft-blocker-backdraft-damper-duct-draft) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-12*
