Engineered as a one-way duct valve, it lets air pass freely in the outgoing direction and closes automatically the moment airflow stops – preventing cold air, moisture and odours from travelling back down your ducting. Built from a galvanised steel casing with lightweight aluminium blades and a stainless-steel shaft and spring, this non-return damper is tough enough for high-humidity areas and withstands temperatures up to 60Β°C (140Β°F). The integrated foam rubber seal keeps operation whisper-quiet and maximises air tightness, while the automatic blade action makes installation simple: push the damper fully into your duct, horizontally or vertically, and it works straight away. Ideal for homeowners, renters and DIY enthusiasts, the WeCooper backdraught shutter is the perfect companion for tumble dryers, bathroom extractor fans, kitchen cooker hoods, air-conditioning systems, garages and in-line ventilation setups, including hydroponics. When you are connecting a 150mm rigid pipe or flexible hose, this duct connector keeps your airflow one-way and your indoor air quality high. ## Features - HOME IMPROVEMENT: Pipe cover flap, butterfly valve. Especially suitable for inserting into 150mm round pipe or flexible hose. Perfect for use in Tumble Dryer, bathrooms, garages ,air conditioners, extractor fan, extractor hoods, Hydroponics, In-Line Extract Fans, and ventilation 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 6-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation - HIGH-QUALITY MATERIALS: 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. The shutter is able to withstand temperatures up to 140Β°F - GREAT FOR HOME USE: The foam rubber sealing on the damper reduces operation noise and provides extra air tightness – ideal for quiet spaces such as bathrooms, bedrooms and living rooms - WARM PROMPT: Please kindly confirm the size you need before ordering to make sure a fit. The 150mm back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you need to use steel duct clamps to secure the backdraft damper ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09TF3X67F | | Best Sellers Rank | 79,473 in DIY & Tools ( See Top 100 in DIY & Tools ) 196 in Ducting | | Brand | WeCooper | | Connector Type | Barb, Compression | | Country of Origin | China | | Customer Reviews | 4.2 4.2 out of 5 stars (327) | | Exterior Finish | Painted | | Inlet Connection Size | 10.5 Centimeters | | Inlet Connection Type | Compression | | Item Dimensions | 10.5 x 10.5 x 9.5 centimetres | | Item Highlight | 6-Inch Duct Connector Valve Galvanised Steel for Extractor Fan, Tumble Dryer & Ventilation HVAC | | Manufacturer | WeCooper | | Material | galvanized steel sheet, Stainless Steel, Aluminium | | Model Number | vent | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Outlet Connection Size | 15.24 Centimeters | | Outlet Connection Type | Female Iron Pipe | | Part Number | vent | | Set Name | Single | | Size | 6 inch | | Thread Size | G 1 1/4 | | Thread Type | NPT | | UPC | 700721630738 | | Valve Type | Butterfly Valve | ## Product Details - **Brand:** WeCooper - **Exterior finish:** Painted - **Inlet connection size:** 10.5 Centimeters - **Inlet connection type:** Compression - **Item Highlight:** 6-Inch Duct Connector Valve Galvanised Steel for Extractor Fan, Tumble Dryer & Ventilation HVAC - **Item dimensions L x W x H:** 10.5 x 10.5 x 9.5 centimetres - **Material:** galvanized steel sheet, Stainless Steel, Aluminium - **Number of Packs:** 1 - **Outlet connection size:** 15.24 Centimeters - **Outlet connection type:** Female Iron Pipe ## Images ![WeCooper Backdraught Shutter 150mm Non-Return Damper Flap - Image 1](https://m.media-amazon.com/images/I/61GtzyGRtgL.jpg) ![WeCooper Backdraught Shutter 150mm Non-Return Damper Flap - Image 2](https://m.media-amazon.com/images/I/31ddsKrWH+L.jpg) ![WeCooper Backdraught Shutter 150mm Non-Return Damper Flap - Image 3](https://m.media-amazon.com/images/I/51Z1TkOFUJL.jpg) ![WeCooper Backdraught Shutter 150mm Non-Return Damper Flap - Image 4](https://m.media-amazon.com/images/I/41RZVgzTnhL.jpg) ![WeCooper Backdraught Shutter 150mm Non-Return Damper Flap - Image 5](https://m.media-amazon.com/images/I/418v2f33jzL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - WeCooper Plug-in backflow flap, DN 150 mm, extractor extractor flap - Aygrochy 150 mm PVC Exhaust Hose, 3 Metres Ventilation Hose with 2 Hose Clamps, Stainless Steel for Mobile Air Conditioning, Dryer, Exhaust Fan, Extractor Hood, Ventilation System --- ## 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.gr/products/468047626-wecooper-backdraught-shutter-150mm-non-return-damper-flap](https://www.desertcart.gr/products/468047626-wecooper-backdraught-shutter-150mm-non-return-damper-flap) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-06*
