WeCooper Connector with backdraught Shutter 150mm, Non Return 6-Inch Damper Flap to Connect Duct Pipe or Flexible Hose Pipe

very good , works as it should without backdraft . far better than manrose with the week spring that might as well not be there.

Well made.

Sorted my problem,works well!

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.

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

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

Seems decent quality for the price, no complaints

Just good quality

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 🫣

Works just fine

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

Para el extractor a funcionado pero cogi otro para el extractor del baño y no se abre falta potencia
