That's crazy, you don't exhaust!
The reason I am returning it is because the 6" ports should be on top, for 6" exhaust fan. I want to exchange air roughly 3 x min. 8x4x7=224×3=672. 2, 4" fans will not give me that. Best rated cfm 4" I've seen is 190. Not enough for me.
Nor me. Just door open and flaps open. Has done the job for me so far.
