Fitting a Bathroom Extractor Fan?

You will not eliminate the noise, but you can reduce it or make it more remote from the bathroom. Look at in line duct fans for a kick off.

Having just completed this exercise I would recommend:

Good quality in line fan. Rubber mounting. Isolate fan from duct with flexibles. Use smooth bore plastic duct with minimum bends. Look at Vent Axia calculator brochure for info. on sizing and install requirements. Go for large bore duct to reduce air speed for a given flow (even if you eliminate fan noise, you will get some air flow noise). Most in line fans will come with fitted or optional timer. Watch out for drop in flow rate with "concertina" style ducting!

I went Vent Axia in line fan with separate timer - very pricy. Time will tell if this was money well spent....still working on bathroom re-fit.

It may be worth you using a fan with humidistat - rather than just the timer sort. That way it will only run when there is something for it to do (assuming it is just moisture leveles you are trying to control)

Phil,

Accepted. The Silavent experience I had was definitely fan noise and the big problem was you could hear it running in the bedroom.

Thanks, some useful tips.

Thanks, I will consider that option.

As the toilet is in the bathroom, there would be advantages to having it on a timer. :-)

Or possibly a manual override to the humidistat.

You have to buy the top brands to reduce fan noise. Vent-Axia, etc. They cost well more than the cheapies in the sheds, but are well made and a "lot" quieter.

CPC do a humidistat one with a pull cord attached that you can use for manual override. It also has a LED that lights when it is on override.
