I took the 4" flange off of the input of the AA Fan so that it's running wide open. It then has the 4" out flange put on there with a 4 to 6 increaser. 6" ducting to the bulb end of the cool tube (6" Dia.). 6" Ducting from the other end of the tube out of the tent vented out of the room.

It's a DR100 39.5" x39.5"x72". Have a tower fan at full blast moving 90 degrees back and forth from the corner covering the entire area.
