WeCooper150mm - 6 inch Connector with Backdraught Shutter, Non-Return Damper Flap to Connect Duct Pipe or Flexible Hose Pipe

I had to send you this back but this was my error. The product has a good rubber seal and is strong but the spring and flaps were too tight for my airflow so wouldn’t open. Product is great but as said not suitable for my purpose.

Slotted neatly between fan & hose; rubber gasket ensures a decent seal when flaps are closed. Springs were a little too strong for vertical use (mounted on ceiling fan) but was easy to twist the arms round so that the flaps were simply held down mostly by gravity; utility room is far warmer now, and fan still works when it needs to.

Where i live can be quite windy at times, and my bathrooms where cold with the draught coming through. This product worked, about 70% better. Simple install, well made, decent price. I had to add spongey tape to get a snug fit. Would recommend 👍

great product

Seems to be of good quality but it doesn’t work with my vent Axya Svara fan. It needs a much more powerful fan.

Really good well made product used to replace an existing backdraft fitting which just rattled in the slightest wind. Easy to fit & went inside existing 6” duct with no problems.

Really well made, I used on a Neff cooker hood and the flaps opened with ease even on the the lowest setting,some reviews suggest that the spring is too strong, seems perfect for a cooker hood especially if placed as close to the fan as possible, I doubt a tumble drying for example would have enough power

Build quality is good, fits well and is good value for money, light weight
