I have an Xperair fan GX9 fitting in the kitchen, having problems and needs to be replaced. Thinking of an Xperair WX 9 fitted ( the one that fits in the wall and does not protrude into the kitchen like the GX9) I consider the hole in the wall will have to be expanded. Am I likely to have any other problems ?
Due to the cost of these Xperair fans, is their a cheaper make on the market that would fit? Peter.
