Fume hood ventilation is this right ?

Now I have for my fumehood duct of 10cm pipe a plastic $20 ventilator which works fine for most experiments but not for e.g. metal melting when the plastic cannot withstand the heat.

So I need a metal ventilator.

I found this one (site in Dutch from an online shop in Holland)
http://www.ventilatorkopen.nl/epages/62166165.sf/nl_NL/?Obje...

It has a 10cm pipe connection and vents 240m3/h (now I have 105m3/h) but is far more robust.
Or can I just buy a second hand kitchen ventilation unit which is normally mounted above the cookplate ?

Not a good idea if you plan to exhaust flammable solvent vapors such as ether. If you do, you need a blower with the motor outside of the gas stream.

The fan that you are looking at looks like it will do a good job. Just make sure that there are no exposed electronics. If there are that could be a big issue, and could cause fire.
