Rated 4 out of 5 by from Does the job. Bought this to replace one that had been damaged by builders. Fitted easily and working as expected. Good price and the usual reliable service from Screwfix.

Rated 3 out of 5 by from Poor design The flap which should be closed when the fan is off is poorly designed - it hangs slightly open allowing drafts and noise. As other reviews had done, I needed to adjust it to try to make it close more. Unfortunately I could not find any small magnets in time, so just added an adjustable bolt to weight it closed. Annoying that the design does not work well, as otherwise it's fine.

Rated 2 out of 5 by from Disappointing Looks OK but you have to butcher the back plate before you even start. Fits round or rectangular solid duct, NOT flexy duct without gluing on solid duct first. Flap does not lie closed. Ended up modifying flap, fitting reversed, and 2 layers of foam tape to fill the gap. It does work quietly like that. Probably better to fit an internal flap valve & a fixed exterior grille.

Rated 5 out of 5 by from good product Used it for cooker hood ventilator. Just push it into the vent pipe. I have pebbledash external walls which obviously prevents a fully flush fit to the wall - bit of builders silicon around the edges, job done. Only thing to be aware of is the flap which does "flap" a little when its windy.

Can a standard tumble dryer hose be fitted to this, in an outbuilding one brick depth?

Asked by: CADJ

What is the distance between the location Fixings? Thanks

Asked by: DIYer214

Is this suitable to be fitted on the underside of a soffit or will the gravity flap constantly be open?

We have a draught coming back into the bathroom through the extractor fan. I want to replace the exterior vent that is mounted to the soffit (as it is just a simple grate at the moment) so would this vent be suitable?
Asked by: TimBrits
I would say not, as the face has to be vertical for the flaps to work. You need in in-duct model. I got one from Amazon as Screwfix do not sell one. Search "Kair backdraught shutter 100". There are other suppliers of similar products. The Kair one should be fitted in a horizontal duct. I haven't tried it vertically. Take care that the open flap does not foul the duct - works best in solid ducting.

How are fixing screws accessed?

It would appear that the item needs to be dismantled...….but how??
Asked by: weathersone
Hello, You would need to push the cowl section on each side and then pull away, this will give you access to the fixings.
