Summary: | A roof mounted ventilation assembly having fluidly coupled supply and relief fans is provided. One drive unit assembly may be operatively associated with both fans. A rotatably and vertically movable duct fluidly couples a supply discharge plenum to a roof-mounted air intake hood so that the former may move vertically and rotatably relative to the latter, thereby the present invention can selectively pressurize the spaced inhabited by the supply discharge plenum through a positive supply to relief air volume ratio. |
