I have a small (160mm square)ceiling-mounted Vent Axia extractor fan in shower room. It's far too noisy. Any suggestions for replacing it, ideally in same hole ? thank you

This fan will almost certainly be a centifugal type fan, which are always noisier than axial fans. My guess is that you have a fully enclosed bathroom and there is no window? if so the only ventilation is the fan. The main reason that a centrifugal fan has been fitted is that these are more powerful than the quiter axial type fans and are capable of forcing the moist/stale air over further distances, normally through a duct which runs to the exterior of the building some metres away. Whilst a new centrifugal fan should be quiter as it will not have worn bearings etc, care should be taken as if a whisper quite axial fan is fitted, it may not move much if any air at all and you could end up with s mould and condensation problem. Some manufacturers such as vent axia and xpelair do offer special low noise models, but these do tend to cost a bit more. Most registered part P electricians should be able to offer you a range of suitable replacements for your existing fan. Hope this helps.

It depends on what space you have above the roof. If it is in a loft then in-line fans are less noisy. Simply buy the fan and mount a grill ( the same size in the space left ). On a seperate issue - vent axia is a good make, if it has always been noisy you might want to check it out before buying a replacement. Check the ducting to make sure it has been damaged or squashed. Also check that it is not too long or has any un-neccesary length in it. Loose or in-correctly fitted duct will vibrate slightly and may be your noise problem. Hope this helps Nigel NJM Electrical

Is there any loft space above this shower room if so I would recommend a in line fan, this is were the fan unit it's self is in the loft and all you have at your shower is a grill , regards Alex (AM Electrical)
