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
Any recommendations for WC extractor fans?

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. Brian

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