Finally making my booth. As stated in other posts, I picked up a squirrel cage fan that is direct drive and so I won't be doing a negative pressure and room size is 5x8. The question I have in design is how to make the in/exit holes. Should the exit be smaller than inlet to force a more direct stream (like concentrated), or should they be larger or even the same size? I know it shouldn't be this difficult, but I'd rather measure twice, and cut once....
Thanks for your help in advance!!! I'll be posting pics of my progress....
