Here is an interesting question that arose during some random things I was doing: If you have a 4" duct, and have TWO 4" fans that you want to connect to it, how does that work? Both are 200 cubic feet per minute, and I want something that will do 400 cubic feet a minute. Its about 4x cheaper to do two fans that do 200 cfm as one that does 400 cfm.
The question is if say you have a "T" or a "Y" split of the duct and both fans are running simultaneously, will the two slow each other down by creating some sort of back suction or not?
