Fits well *by on Reviewed in the United Kingdom 5 July 2026* These plastic components are not always compatible but buying all Kair made parts meant they all joined up no problem ### ⭐⭐⭐⭐⭐ Stops the draughts *by on Reviewed in the United Kingdom 10 July 2025* Put this in our kitchen extractor fan vent to stop cold air in the coming in from outside.Read some reviews that people had found this rattling a bit when in the vent hose but haven't found these issues for us. Works well and significant drop in the cold air coming in through especially during windy and cold winter days.Worth the money for a quick DIY fix. ### ⭐⭐⭐⭐ Works fine but needed small modification to prevent it sticking open in my installation *by on Reviewed in the United Kingdom 6 September 2024* I installed this in a vertical duct above my cooker hood. I was getting cold draughts coming in during the winter and this completely solved that problem.There was one small issue in that when mounted vertically it is possible for the flap to open more than 90 deg, tip past the vertical and then stick in the open position. I added a small screw to prevent it opening more than about 85 deg and this seemed to fix that issue. ## Frequently Bought Together - Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Kair 90 Degree Elbow Bend 150mm - 6 inch Round Plastic Ducting Joint to Connect Round Duct Pipe or Flexible Hose - Kair Plastic Ducting Pipe 150mm - 6 inch / 350mm Short Length -Rigid Straight Duct Channel --- ## 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.tw/products/412374886-kair-150mm-6-inch-backdraught-shutter-ducting-connector](https://www.desertcart.tw/products/412374886-kair-150mm-6-inch-backdraught-shutter-ducting-connector) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-27*
