is it suitable for a tumble drier and also a toilet fan.
Hi would a cowled grill be preferable for an application where it is subject to prevailing winds.
Hi. What plastic duct should I use to feed to this from the extractor fan ?
The male spigot on this 100mm Domus Cowled Grille will fit inside our Kair System 100 Round Duct Pipe.
The pipe is available in three lengths, so I would suggest selecting the most appropriate length for your cavity wall and duct run. Please see below for the hyperlinks to these products.

My kitchen extractor fan has a 200mmx200mm external grille on the outside of the wall which has 4 gravity flaps which rattle in the wind. Is there a cowled outlet grille the right size I can replace it with? Many thanks.
Would this product help reduce sound from a vent? If not, can you recommend any other product that can reduce noise from my neighbour's kitchen extractor fan? Thanks.
Hi, the product description of this black version calls this a cowled grille but the video is of a cowled product with a damper inside it and there is no grill that I can see? Is there a grill? I am looking for an outlet for my 150mm ducting from an extractor fan and I want to minimise noise. Thank you. Philip
Hi, Can you confirm that my order is for a 4" unit? Regards John Ridge
is this product suitable for gas hops
We have an outlet with a gravity flap and when the wind blows from a certain direction it drives us mad banging all day and night. Would the damper prevent this and how is it dampened?
Are they suitable for a vent in a room with a gas fire.
Hi, my bathroom extractor is fitted to a Screwfix vent - Manrose Cowl Vent Brown 100 x 100mm (14789) - but as it's NE facing it is still subject to rattling in the wind and is not doing what I want it to. Will your product minimise the wind noise? I prefer black as the colour.
