sizing ventilation system help

Postby cwk266 » Thu Sep 27, 2012 3:49 am

Hi I would like to change my existing ventilation which is a 100000 cfm exhaust fan with a open fresh air inlet that is running at a slight negative pressure to having a inline duct fan in a 30ft length of duct with 5 outlets evenly spaced and a end cap that will supply the fresh air for the exhaust fan.My question would be what type of inline fan tube axial or??What should the cfm for the intake fan be and what size of outlets would be required.The outlets would be unrestricted and the goal is to have the air out of the outlets have enough velocity to reach the opposite side wall which is 39ft.Thanks in advance for any tech input
