Thread: CFM Chart

  1. #1

    Question CFM Chart

    As a helper and novice -
    Is there a basic CFM chart for the various flex duct sizes somewhere on the web. I have received different numbers.
    from different techs. 5 inches to 14 inches

    Basic Manual D ,from http://www.acca.org ,is that it depends on the total equivalent feet of duct in each system, to know what each size duct will move in cfms.
