Hi Raymond,
I have not heard of that brand of fan, I will research them tonight. When I am talking about flow, its not air flow but the flow of the room. This will be a multi purpose room with 2 tables and so I need to have them both accessible and useable.
Can you be more specific about the issues with vortex fans? I have not heard anything bad about them and I thought they were recommended.
I have also included a drawing of the side view of my soon to be hood. I have a solid back and side baffles down to the table .
Thoughts? Concerns?
