C4PS 4-inch Simply Silent Contour Extractor Fan Pull Cord

My old bathroom fan wasn't working when I moved in, so decided to buy a new one and wanted something that didn't just look like the normal circle with vents in it. This is that - it definitely looks more appealing and higher quality than a standard fan. It also feels higher quality. The installation was painless (although as the old fan was bodged in, I had to fill holes in first!) and the fan is effective in a bathroom with no window. It is a bit noisy though I run it on the higher speed setting, and I suspect that's not helped by my flat being rather small. If I close the bathroom and bedroom doors, I can't hear it (though then I imagine it struggling to pull air in the bathroom!). The noise isn't too annoying though. I've definitely had far worse! The timer - though not very well labelled for running time - is very easy to set with a small screwdriver, a stopwatch and a bit of experimentation. Edit on 22 May 2017: I've been so pleased with these that when my parents needed an extractor fan replacing in their house, I immediately purchased one of these and put it in. Still recommended! (Though setting the timers run time is still a guessing game)

This is a brilliant fan that is whisper quiet as described. However I would suggest that the higher speed is selected on install as the lower speed would only be any use for a continuous on situation as it does not move enough air otherwise. This fan was a direct replacement for one that had been installed for many years in conjunction with a bathroom light switch & the C4S made it sound like an old tractor by comparison. Installation was very simple with just a Neutral & a Positive connection. It was not even necessary to drill new fixing holes in the wall due to a very neat arrangement of two small spikes that grip the internal vent hole by tightening two small screws after inserting the body of the fan into the vent hole. I can highly recommend the C4S as it sets the standard by which all those nasty cheaper fans should be judged.Delivery was by return so what more can you ask!

I bought this to replace an older extractor that was (a) very noisy, and (b) didn't have a separate cord switch, so it was always on when the bathroom light was on. I'm very happy with this product as it's very quiet in operation, it was very easy to install using the existing wiring, and it clears the steam from the bathroom very efficiently. The product has two settings which you choose between before installation, although you could change the setting again post-install without too much hassle. I picked the faster setting to extract more volume of air and it really does work well.

fa il suo dovere egregiamente ha due velocità di funzionamento e questo modello non dispone di igrometro, personalmente l'ho tarato sulla velocità massima ed il suono è mio parere accettabile per la massa d'aria che è in grado di muovere, a velocità più bassa è appena percettibile. Di facile montaggio dispone di timer regolabile ovviamente si deve avere l'impianto predisposto con tre fili, in quanto l'aspiratore deve prelevare durante il funzionamento con il timerr l'alimentazione diretta.

Montage facile mais pas très solide : on aurais préféré 4 vis à chaque coin, plutôt que 2 petites pattes qui n'ont pas bcp d'emprise dans mon faux plafond. Il a l'air de tenir quand même. Concernant le bruit : je n'ai pas vu de variateur de vitesse; et il y a un petit cliquetis dans les pales, j'ignore où cela touche les bords je ne vois pas. Ca ira bien avec la tirette pour aérer de temps en temps.
