Does anyone know if this kind of ducting is suitable for a cooker hood with
600m2/h extraction:

I assume it's so cheap because it's more or less foil on a wire helix?

How long a length? What kind of fan in the extractor?

I've got the same stuff for a 450m3/h extractor, and no problems. As it's
150mm, I'm sure it can probably take plenty more.

Looking elsewhere I was being quoted nearly £100 for a 5m length of 150mm
ducting with wall plate!

Including the run up the chimney section of the hood, approx 4m with 2
90deg bends. I've no idea if the fan is centrifugal or not I'm afraid (can
you tell by looking?).
The hood is a Brandt AD229X and no tech spec has been supplied with it, or
on the website

That should be OK. If you can do the bends using the ducting and
curve it rather than using elbows then even better,

Yes. The impeller inside looks like a drum with blades around the
edge, rather than like a propeller.

Ah! It is centrifugal then - with two intakes, one at either end of the
axis.

Cheers Andy

That sounds fairly steep.
Have you looked at the Domus catalogue (available as a .pdf file
downloadable from their web site (www. domusventilation.com look
under 'ducting') and then asked a builders merchant to quote.

(If you know the fan performance, the catalogue also explains how to
calculate the suitability of different types of ducting.)
