The never-ending list of jobs has now reached the point of needing an
extractor fan for the new loo. The requirements are straightforward:
effective, wall-mounted, quiet, no timer.

How long duct? Over a couple of metres you need a centrifugal fan.

That's easy: avoid a 4"er. Yes they're cheap, but don't shift much & are the noisiest. Also look at specs, noise varies greatly. And in some cases you can just use a vent/flap, no fan required.

Oh really? They are more noisy quite often. I'm sure I've seen ordinary fans
with longer ducts, but most were straight.

4", Air Extraction: 97m3/hr / 26 L/s Noise: 25dB(A) Wattage: 7.5w

As with any axial fan, the pressure capability is low.

It needs to be wall-mounted and will exhaust straight through the wall

Things are so complicated nowadays. Time was the privy ventilator was
just crescent, star or diamond.

I fitted an Envirovent
extractor fan recently. SIL100T is the 4"
timer version - on eBay around 30 quid, there are other versions
- pir, humidistat, etc. Looks very similar to the other
recommendation

After posting I looked at more details (my old Vent-Axia is making the odd
noise) and saw that it can take a lot of duct.
If/when I need a new one this'll be it.
