Default Ventilation Choices

Down to my final large piece needed to finalize the brewery. I know it's best to go with the vent set up Kal recommends but I'd like to try and not spend 20% of the overall brewery cost on ventilation. I brewed two five gallon batches at a time on my old stove using a microwave vent fan for many years with doors and windows closed in my one bedroom apt. Yes my place got really humid, smelled amazing, and eventually I had to clean the vents but I never had condensation anywhere. I'm sure I was doing unseen damage to the place, luckily it was a rental.

To keep costs down I've decided to go with a vent just over the boil kettle. I'd rather do a ductless version and just open the door and windows so I don't have to cut holes in the wall to the outside (not great re-sale value in a townhome kitchen) but if I do end up running ducting I only would need one right elbow from the top of the hood, then about four feet straight to the outside wall. Brewery is located in kitchen right next to a door and two windows.

I may end up building a hood myself and getting the vortex fan but I'm REALLY tempted to go with something like one of these if they would work.

What size batches are you doing? Assuming electric, and these being just to remove evaporation, I can't see why the lowest (760cfm) option wouldn't be more than enough power.

I agree with Brett. If it's only for moisture.

I would even consider just a bathroom fan type of setup. Most are much lower power, and much less expensive. They provide about 100 CFMs. If it's enough for a hot shower, it should be enough for a small 1 hr. boil.

The larger hoods you have links to should help keep the smell down too, if that's worth the extra couple hundred bucks to you. Plus they look way cooler!

Ya, I read it as the OP was looking to replace their existing hood in their kitchen?

I currently don't have a hood where I'll be setting up my Kal clone electric brewery. 90% of the time it will be 5g batches with the occasional 10g batch. I was going off of Kal's ventilation recommendation, they seem over the top for what I'll need but I'd hate to get something set up and it not work well just because I tried to save a few hundred dollars. I don't care about smell at all (love when my place smells like wort) and it'll be in the corner of my kitchen next to a door, there's also two windows on the opposite wall.

Simple cheap solution if you don't mind sticking a fan in the window when you brew.

Or perhaps this link, I never knew there were window fans that pemitted opening / closing the window when mounted???

Just a couple suggestions, completely understandable if you want a professional looking hood set-up.

I'm using a Vornado fan on top of a hutch that blows across the top of my kettle and points toward an open window. Without it I got rain drops forming on the ceiling even with a large ceiling fan running in the center of the room. With the Vornado running, no problems with moisture build up or condensation anywhere in the house. I think it's somewhere around 500 cf/min.

I was thinking about using a fan to blow the across the kettle towards the open door which opens outwards but usually the cross breeze comes in through that door. Boil kettle is the one on the far left and the control panel will be mounted on the far right next to the door.

I love Amazon Warehouse for items like these. I recently bought one of the 400cfm vortex fans (used-like new) and 2 of these to cover the whole work area. They are now around $25 a piece but when I purchased them from Amazon Warehouse they were only $11 so I couldn't pass them up.

I will be putting a piece of clear plastic I have left over from a DIY projector ceiling mount I made to cover the top holes (I considered insulation like used on keezer builds around the collar as well) with the hood over the BK having a cut out for exhaust. I will use a 45* angle connector to the hose to keep it as low profile as possible. The hoods have two screw holes on the sides to bolt them together and then I will use a pair of clippers to cut the metal in between to make one large 5 foot hood.

This will exhaust out of my dryer vent I have in the same room. With the 400+ CFM fan I have read condensation is not a problem at all so I was not worried about a lip for condensation drip.

So overall cost will be roughly $110 or so with the connector and hose I still have yet to buy. I also trolled craigslist for some range hoods and found one similar to your first link that someone was trying to get rid of for $100 but they were 3 hours away so I didn't jump.

Hope this helps at least to give you ideas of outside the box hoods.
