I want to replace my bathroom extractor - looks quite old and is a
strange size (I think) the front cover is, 160mm x 160mm. I can't see a
make on it but it is one of the type that switches on and off with the
light and stays on a minute or so after switching it off.

I want to replace it as its noisy but with a pull switch type so it
doesn't come on with the light all the time.

Any ideas on replacement? I don't need to replace the outside wall
louvre as it looks and works ok.

further to last post, have taken the extractor off to look at it, it
says 5927 timer model on it and no make.

Notice that it has 3 wires - 2 red and one black, if I was replacing it
with a switched type how many wires do they have - thought they had 2
wires? would it set any problems ?

Thanks

The unit has a timer in it.

There are two red wires - one from the raw mains, and one from the light
switch.

In use teh switched mains switches it on, and sets the timer.

It then runs off the unswitched mains for a few minutes if the light is
switched off.


You can get fans with pull cords built in. And with humidistats and the
like.

Wire em up to your taste.

Thanks
