Blow Back Extractor Fan

[Deleted User] · 2021-02-13 17:33:33

Hi folks For sure it's windy out there and have noticed very significant blow back via the kitchen extractor fan which I think is always there, but just less obvious. Is there an extractor fan exterior wall fitting that will significantly reduce blow back or will there always be a level of blow back into the kitchen? Thanks

You need an outside grille with back pressure shutter.
Something like this depending on your duct size

The oven extractor should also have a shutter.
