🌬️ Stop drafts, start comfort — the smart duct upgrade you didn’t know you needed!
The WeCooper 6-inch Backdraught Shutter Connector is a high-quality ventilation accessory designed to fit 150mm round ducts or flexible hoses. Featuring a galvanized steel casing, aluminum butterfly valve, and stainless steel components, it ensures durable, heat-resistant operation up to 140°F. Its automatic one-way airflow damper prevents backdrafts, reduces noise with foam sealing, and installs easily in both horizontal and vertical positions—ideal for dryers, extractor fans, and HVAC systems.

Great product.
Purchased this to replace the plastic one that came with a manrose in line extractor after I heavy handedly broke it. Glad I did as this is a far superior products and works great.

Good product
Very good product, well made and fair price. Installed on a Bosch kitchen extractor and the flaps open at all the 3 speeds.

Backdraft vent
Bought this to stop a draughty vent in a bathroom. The product is very well made but was not compatible with my bathroom fan as the spring connector was too strong for my fan, and couldn’t open the 2 flaps

Does exactly what it says. Unfortunately I had to remove it as it made a clicking noise when the wind blew which terrified the dog 🫣

Buen material, pero no es 100% estanco, aunque si reduce mucho, en mi caso el ruido del aire que entraba por el tubo
