Is there a reason you don't just use the 90° elbow alone, or a M-F 90° elbow coming out of the 45° piece? That is, it would be rotating out of the return, rather than crossing the container and starting against the opposite wall. I feel like this would raise the vortex to the top of the container, no matter how much you brew, allowing for the maximum amount of surface area for gas exchange... also, less stuff in the way.
The bulk head come into the tank several inches, I went with this setup, as you need to be able to Move it up and down like an arm, I can lower it and make a 3-4 gallon batch if I needed.
(I feel like this would raise the vortex to the top of the container) I'm not getting what your talking about here, there is NO WAY your going to get a faster or deeper Vortex with this setup, Of course someone could revise it, but this is simple, easy to clean and works, Hell build one and test it out!!!! Check out the pics I posted on the previous page, I just don't know how much better of a Vortex you could get using just
AIR .I'm not seeing why anyone would need or want more then that. If you find something that just makes it better on Your Vortex Brewer please hit me up and post it here.;)
