I have a pretty large round fan, prolly about 10-12 in diameter and i have a homemade reducer hooked up to it down to a 4 inch vent covered w a homemade carbon filter. Im just wondering if anyone else has had the problem of the fan blowing air out of the front and the back? lol its really powerful but when its running instead of sucking air in thru the back it blows air out of the back... and the front.
