Ventilation question for eBIAB

[ishcor2000]

Just wondering if anyone has used this range hood on ebay for venting in an unfinished basement for an ebiab system.

Just wondering if this hood would keep up and help minimize moisture if i ran some duct work (less than 10' of duct) and vent it outside.

Curious to see what everyone thought. Thanks

My guess is that it would suffice, depending on the intensity of the boil. Not a huge deal if it falls behind a bit during the boil IMO, just let it run for 30-60 minutes after flameout.

Electric brewery mentions 300 cfm, this unit has 700 prior to adding ductwork...looks promising...

Thanks wilserbrewer. I was thinking same thing.

P.S. And thanks for the super fast shipping and the awesome bags!!!

Unfortunately CFM numbers are basically meaningless. It depends on the length of the run, how many turns, diameter of the duct, and the type/quality of the fan. it also depends on how vigorous the boil is. Given the extremely low price I would not expect anywhere near the rated CFM other than if the fan was blowing with absolutely nothing connected.

Does that mean it won't work? No, it just means that unless you get mech specs on the fan and how it behaves with duct loading, it's a guessing game.

For an electric based brewery a good rule of thumb is to divide the element size (in watts) by 17.6 to obtain the required CFM (cubic feet per minute). In my case I use a 5500W element in My boil kettle. 5500 / 17.6 = 312 CFM. I therefore require a fan that can move a minimum of 312 CFM in order to ventilate our electric brewery properly. Fans this size are readily available and reasonably inexpensive, you just need to make sure that the rating doesn't drop well below that once you add ductwork.

Already placed the order before reading Kal's input. As with most things on ebay it all seems to be a YMMV deal.
I'll just hope this fan doesn't suck or maybe I hope it does.

You definitely want it to suck.

You'll likely be fine - I just wanted to point out that CFM numbers (and comparing them between models) is a somewhat useless thing to do. There are so many variables.

Make sure to post back on how it works to help out anyone else looking/reading...

Good luck!

I bet it will still be adequate. It looks nice, has lighting, and is at a good price. Make sure and update how it works after you get it hooked up. If the fan turns out to be really weak I'm sure you can disable it (if needed) and hook up an inline fan in the ducting right after the hood.

To the OP - Can you share how this worked out for you? I'm looking at something very similar for the same situation you are in. Did this work out well for you?

Thanks!
