Review: Fit for purpose, with some modification. - Bought this to retro fit in the ducting of a 12v Manrose bathroom fan which, for some reason and unlike its predecessor, came without a backdraft shutter. As other buyers have mentioned, its a tight fit in 100mm ducting and I had to trim the outer central ridge on the shutter to fit it inside the ducting. Used a very sharp paperhangers knife to shave a millimetre or so from the ridge and it now fits perfectly, held in place, just in case, by a blob or two of silicone. Its working well so far: yes, it clatters when the wind blows but that goes with the territory when, as we do, you live in a windy coastal town. Not sure how long it'll last given the wear that the wind will place on the shutter's basic hinges, but Time will tell. Very easy to retro fit if you have the access, so recommended. Review: A good price. - Returned as wasn't needed. But the quality looked good in the packaging. ## Features - 150mm / 6 inch plastic ducting connector with inline backdraught shutter / gravity damper flap. - Stop smells and prevent cold air coming through your extract fan or ducting. - Will fit inside 150mm round pipe or 152mm flexible hose and can be used to join multiple lengths of pipe together to form a long duct run. - Perfectly suited for ducting your Tumble Dryer, Bathroom or Kitchen extractor fan, Hydroponics, In-Line Extract Fans, or Cooker Hood and other ventilation applications. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004X4SV8M | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 5,240 in DIY & Tools ( See Top 100 in DIY & Tools ) 7 in Ducting | | Colour | White | | Customer Reviews | 4.3 4.3 out of 5 stars (2,836) | | Date First Available | 19 April 2011 | | Item Package Quantity | 1 | | Item Weight | 99.8 g | | Manufacturer | Kair | | Manufacturer reference | DUCVKC363 | | Material | Polystyrene | | Part Number | DUCVKC363 | | Product Dimensions | 15.19 x 15.19 x 6.2 cm; 99.79 g | | Size | 150mm (With Flap) | ## Images ![Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Image 1](https://m.media-amazon.com/images/I/41JzPWXI1RL.jpg) ![Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Image 2](https://m.media-amazon.com/images/I/41rG0C0UKaL.jpg) ![Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Image 3](https://m.media-amazon.com/images/I/61oeG+fcQ8L.jpg) ![Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Image 4](https://m.media-amazon.com/images/I/61us8dqvHXL.jpg) ![Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Image 5](https://m.media-amazon.com/images/I/61Er40rgLjL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fit for purpose, with some modification. *by B***N on 26 January 2025* Bought this to retro fit in the ducting of a 12v Manrose bathroom fan which, for some reason and unlike its predecessor, came without a backdraft shutter.

But the quality looked good in the packaging. ### ⭐⭐⭐⭐⭐ Works really well. *by J***N on 5 February 2026* This works really well, it has a plastic lip half way down which you can shave a bit off to fit inside / in the middle of a 100mm tube. They're hard to get in stores for some reason, but it works really well, as soon as the fan starts it opens, then closes when it's off. ## 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.gr/products/50213535-kair-connector-with-backdraught-shutter-150mm-6-inch-non-return](https://www.desertcart.gr/products/50213535-kair-connector-with-backdraught-shutter-150mm-6-inch-non-return) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-25*
