smells coming from the extractor fan

[jduncan69]

i have a ceiling mounted bathroom extractor fan which exits through the roof, is it possible to adapt so as to remove smelly back drafts when not in use?

thanks for any help

we had a fan with a non return "flaps" they close when fan not working, opened by pressure of fan, is that what you mean?

Smelly back drafts?

Lay off the curries mate

You can buy an inline backdraft shutter to fit inside the flexihose / ducting
Get them from a local electrical wholesalers

Andy (or anyone else), I have only seen these included in the fan housing and could do with putting one into my exiting duct work (just to stop drafts not smells). Can you give us a clue as to where you think these can be purchased ?

Thanks Andy, I wasn't being lazy on the search front, I knew about those. Some fans come with 'butterfly type' shutters in the fan housing which snap shut to close the housing when the air flow stops (fan switched off). I thought it was that type of device but independent of the fan, that you were referring to. Thanks anyway.
