I am in the UK. Can anyone recommended a 6 inch (150mm) window-mounted
extractor fan for a kitchen. Good value is important as I'm on a
budget.

I want a fan that is not too noisy or too powerful as the kitchen is
small (under 30 cu metres).

Could I use a variable speed controller like this one

Or does the fan have to be of a certain type? For example, able to run
at slow speeds, have a certain number of "windings", use a particular
method of starting, or whatever.

My old fan was 255cu m/hr (35W) and it was claimed the noise was 49
dBA. It was quite loud (1800 rpm) and too powerful.
