• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

OK, I realise that silent is not very realistic but we're after a really quiet one. Victoria Plumbing advertise one with noise at 26dB which would be OK. If it actually was 26dB. But in reality it is 4x noisier as measured on my dB meter and Mark 1 lugholes. They did send a replacement but just as noisy.
 
The two main issues with fans are motor noise and blade tip noise. The smaller they are the faster they need to move to shift enough air. On small ones this pushes the motor noise high because they're small and whiney, and tip noise high because they're travelling so fast.

Larger fans tend to be quieter due to larger motors not having to work so hard and larger fins moving more slowly, generating less tip noise.

Unless you have a fairly large fan I don't imagine there's a suitably quiet one that exists out there without paying a LOT of money, or being prepared to buy one and swap the motor out for a better/more expensive model.
 
A bit off topic perhaps but perhaps something similar and simpler is available in UK.

Over here rather than have individual ceiling fans VMC (mechanically controlled ventilation) fan units are installed in the loft space . One unit extracts from all the wet rooms rooms, kitchen, WCs, bathrooms.
This one available from one of the sheds shed rated at just 11dba.

We certainly can’t hear ours and it is on 24/7. I have to hold tissue paper up to the vent to check if it is still on.

Thanks, chaps.

Thanks Andy. I'd seen that one but reluctant to shell out that much TBH. Humid air from the en-suite has it passed through a dehumidifier in the loft and the dry air (including the heat it had ...well, most of it) returned to the en-suite.

My reasoning for a small extractor was really only to remove certain smells but LOML assures me that she doesn't make smells! All the wiring is in situ and so I may not bother with one for the moment and see if I get a request at a later date.

Of course they don't Roger, I'm surprised you didn't know that. :ROFLMAO:
You don't have kids but those of us who did as well as a dog are fully aware that on car journeys the dog always got the blame. 😉

A few years ago I needed a larger removal of air in our old bathroom but I really really hate the noise so I installed a more powerful in line motor in the attic, worked well and virtually silent, reminded me a bit of a double ended bench grinder lol.

Panasonic WhisperQuiet fans, if you can get them where you are.

Yes they are available here but very spendy . Also they are only designed for ceiling extract which I can’t do.

A lightbulb moment just now makes me wonder if I put the fan at the other end of the ventilation pipe might work. Potential water ingress notwithstanding

Even a very quiet fan can be noisy if installed badly, a quite option is to use an inline fan in the loft and just duct it. This model is good and compact as well as quiet.

As I have already stated, venting via the loft or ceiling is not an option.

Out of interest I just looked up the vent axia 479086 from Andy’s link on the internet, it can be had for £54 which doesn’t sound bad for a supposedly silent extractor.

That’s a screen shot of the search I did, if you don’t fancy an unknown company Toolstation do it for £62.98
