Good product and is working well.
Its very good product. Had to trim slightly on OD ridge to fit inside 110mm waste pipe in wall. But I knew that before buying. Its working really well, but wish it had been a bit cheaper. However, not complaining.Verified purchase: YesCondition: New

Effective Back Draught Units
Good value back draught units to stop the cold air/breeze coming through a room extractor unit. Much better than the twin flap with springs type of back draught unit. These gravity operated flaps don’t need any springs & should last for a long time. Have to be careful how these units are positioned in the trunking to make sure the flap doesn’t catch on the trunking when in open position but are very easy to fit and very good value for money.

Flap valve
A very simple piece of equipment that does exactly what is required. Works perfectly in a vertical position right behind a ceiling mounted fan which has an extraction rate of 73m^3/hr. Might work horizontally in fans with lower extraction rate, that would struggle to open the flap. What I don't get is why a bit of plastic worth less than 0.001 pence ends up costing so much when mass produced.Verified purchase: YesCondition: New

Back draught shutter saves money.
Easy to fit with plastic ties &/or heavy duty adhesive tape. The wind can be strong here but it stops the draught coming into the bathroom. And it saves money on my heating bill.Verified purchase: YesCondition: New

What I ws looking for.
Better than the shutters mounted on teh back of fans as these tend to rely on little springs that eventually break. Standard flexible tubing fitted snugly to each side of the shutter - secured with stainless steel hose clips for a long term fix.Verified purchase: YesCondition: New

Works great
Perfect. Connected two extraction ducting via a ‘Y’ branch. This back draft connector prevents air from one extractor to be blown into the other. Great value and works a treat.Verified purchase: YesCondition: New

Very effective back draft shutter
I've installed these and they eliminated cold air flowing back through the vents. they need to be mounted horizontally to be sure the flap closes properly, other than that with work very well.Verified purchase: YesCondition: New

Cheap but I suppose you get what you pay for
Supposed to be a back draft stopper but the flap and where it swivels on is very poor quality so not really fit for the job it’s supposed to do. Ended up buying a more superior model that was better suited for the jobVerified purchase: YesCondition: New
