HI I have recently purchased a hygena app 2420 extractor fan and can’t find anywhere in the instructions where it can be changed to recirculation mode as I don’t have access to a outside wall.
I just thought when I purchased it that they all can be changed to recirculation mode and not all of them have to be flued out.
Is it something I am missing or can anybody help.
Thanks Shaun
but in recirculation mode you have to have carbon filters fitted to stop smells recirculating
so if your model has not got them its not suitable either or you would have to add them if they are available for it
has the model you have got grills at the top of the chimney? if yes fit it to the wall and the exhaust air comes back into the room through these vents but you still must get charcoal filters
