Inline Duct Fan Recommendations?

[jam095]

Looking to build an exhaust system for my 3500W induction BIAB setup. Doing the math, looks like I need to be around 200 CFM or greater. Going to use a large pastry bowl as a hood.
Any recommendations on an inline duct fan? Trying to be conservative with this project.

I'm going to be building a brew room this summer, well I built the room already, going to outfit it for brewing this summer. Where can I find info on the calculations needed for my hood?

Just a point of reference for you. I bought this one, and it is a beast. I am doing 10 gallon batches with a 5500w element. I don't need much of the power, I would have been fine going smaller/cheaper.

Haus, Blichmann has published an article in BYO at least twice now on the subject. For electric, you divide the max watts of your element by 17.5 (i.e. 5500/17.5=314 CFM<) It's much different for gas.
