Re: One or two ducts to center vent?

the static presure or the air would increase by going with a single duct, but you will loose CFM ,(Cubic ft per min ) because you are transitioning the air flow in to a smaller area.

What i am trying to say is ....its like turning your water hose on and then puting your finger over half the outlet of the hose..........
