Kair Ceiling Extract Valve 100mm - 4 inch White Coated Metal Vent

Ricevuti perfettamente in tempo. Li ho utilizzati in una contro-soffittatura. Molto belli e perfettamente verniciati. Sono solidi e si avvitano perfettamente alla parte inferiore (che ho avvitato nel cartongesso).

Easy to fit, good quality. Paint finish isn’t the best but a bit of compound smoothed it up

I ordered this as a bit of a gamble to replace an existing fresh air intake in a WC. It was reasonably cheap so I thought I’d try it out and take the hit if it was rubbish. I wanted a vent that was adjustable and could be fully closed for winter months as currently when it is below freezing outside I have to take the plastic grille off my existing vents and fill the hole with a foam cutout. The reviews weren’t clear on whether you could do this, but you can. There is a nut on either side of a thread and you need to remove one of them (one is to make sure you don’t overtighten the vent and one to make sure you don’t loosen it so much it falls off). As a result I have now ordered another three to replace the other old plastic style vents I have. The only slight downside is the rotating part of the vent is slightly bent in that when it is in the open position one side has a slightly larger gap than the other, though as it is against a wall it’s not a dealbreaker for me.

Simple and stylish. Easy to fit. Adjustable and quite slick when installed

For fitting the screw holes are small and close to hole edge, so tricky for say plaster board, and whole thing must hang below ceiling. Would benefit from a plate which could be fixed to above ceiling side to sandwich together at various depths/thickness of ceilings/walls. This would be more robust and secure.
