Hi Guys,
Rather than brewing today I finished up my venturi wort aeration system. I thought someone might benefit from all the trial and error I did pulling it together.
My first several takes on this were inspired by threads on HBT (https://www.homebrewtalk.com/f51/cheap-easy-aeration-gadget-68218/) and this one (http://randystacye.com/diy_venturi.htm) but I found it didn't pull as much air in as I wanted. So I read over a few spec sheets for the various produced venturis that would fit my 1/2" system and stumbled onto this crazy video on YouTube: .
Long story short, I ended up making the system in the attached pics. This is a Mazzei 484 1/2" model (the clear model in the YouTube vid above is only a demo, I called Mazzei to try to buy it) with 304 stainless on the inlet from the BK and schedule 40 PVC on the outlet (it is only rated to 140F). You can Google to find all of this stuff.
Along the way I found the other guy who has a clear Mazzei (http://waterreclaim.com/product/ozone/manifold) and he gave some helpful tips: make sure you have at least 6" before and after the venturi to line up the flow and maximize aeration. He also said the way he set up his system on the pic above was far more effective than the way I eventually went with. But I'm not shooting to aerate a full municipal water supply like he is, so I'm fine with it.
Anyway, enough with the typing, here are some photos of it before and during operation. When running there is a solid column of foam that comes out after the venturi (the black T with a periscope for an air filter). Awesome! I'll brew with it next weekend and am sure it will be a game changer for my yeast.
Cheers!
PS if anyone comes up with a clear Mazzei please let me know! :rockin:
