Abstract
A ventilation fan which is adapted to be ceiling mounted such as in an attic space above a room ceiling. The fan is arranged to pass upwardly through the space between the ceiling joists in a compact arrangement and to be extended once it is disposed above the room ceiling to define an operating configuration. In the operating configuration, the air moving apparatus is swung outwardly from the housing of the fan on a pivotally mounted wall portion thereof. The fan redirects the upwardly flowing air from the subjacent room at a substantial angle to the vertical in the attic space for improved ventilation functioning.
