I have a 5x2x6.5 foot closet that I cool with a 6" inline fan rated at 400cfm. There is some short ducting, a tight turn, and a 6" carbon filter. I have a sheet of mylar with a zipper in it as a door. I have an 8" intake at the bottom. When the fan is on it sucks the tarp in very hard. It wouldn't be a problem but the strength of the pull keeps unsticking the zipper from the mylar. What is a more appropriate intake size for this setup. Would adding a 4" intake, or 2, above the 8" one be effective?
