I am going to install a Vent-Axia Eclispe 100XT extractor fan in my bathroom, through the wall. It is 220-240v, however they say it is IPX4 rated, even though i would have thought it would have had to have been 12V, in order to meet this spec. I have got two positions that i can install it, on the furthest wall away from the door (2 metres only a small room). One position is above the bath at the opposite end from the shower, or the other position is in the opposite corner of the room about 1.5 metres from the bath. Would either of these positions be better then the other, or would it work just as well in any of them.
