Does anyone know a source for a kitchen exhaust fan designed to fit a corner application? I’ve searched the web and checked with numerous appliance dealers and no one knows of one. I’ve designed a layout with an electric cooktop sited diagonally in a corner and don’t want to use a down draft ventilator as they take up the entire cabinet and don’t work well anyway. My other alternative is putting a register and duct work in the wall and using a remote exhaust fan. I’ve seen them mentioned in Fine Home building but can’t locate them on the web or in any appliance store. Can anyone provide me with a lead? I plan to use round flex aluminum ducting. Any suggestions on minimum diameter?

Joel, try http://www.fantech.com
Depending on how long the run is and how many turns; and depending on the kind of cooking you do, 5" is the minimum and 6" is better. I have seen 7" and 8" but they are not the norm.
Tom: I have to use a downdraft because of the construction of the house. Went to Fantech & the rep told me I better get an 8 inch fan. Will probably suck my wife's wig off. It is humongous! Takes up half the cabinet next to the range.DonThe GlassMasterworks - If it scratches, I etch it!
Ha, now I make the connection: my kitchen exhaust is pulling my hair thin.
Checked out the Fantech site. They list airflow as .1 - .2 cubic meters per sec which by my conversion is less than the 200 cfm of even the lowest priced US units. Am I figuring wrong? Who's a US dealer?
Try EFI.org. They have a whole line of Fantech stuff and lots of other goodies.

One cubic meter = 35.3 cu ft. So 0.1 cubic meters/sec = 3.5 x 60 cubic feet per minute = 210 cu ft/min. 0.2 cubic meters/sec would be twice that.
silly me - I calculated wrong. Thanks.
Dan has the right calculation.
Sorry, the US Fantech site is http://www.fantech.net
They have kitchen units with airflow from 200-800cfm.
For a residential hood, range setup, 250 - 300 cfm exhaust is good. For that you would need an 8" exhaust duct or the equivalent. I would not recommend either aluminum or flexible duct. If you use a remote fan (in the basement under the kitchen?) an inline cabinet fan is readily available from a dozen different manufacturers.
I've got a fantech outside mount kitchen exhaust fan with the muffler they sell. Moves an incredible amount of air with an incredibly small amount of noise.
I'm thankful for the loyal opposition! It's hard to learn much from those who simply agree with you.
