Xpelair GX9. / WX9.
 

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?
