Abstract
A ceiling ventilation device, mountable in an opening in a ceiling between a pair of ceiling joists, includes a pair of mounting brackets. Each bracket, attachable at its ends to a pair of ceiling joists, includes a pair of spring biased mounting tangs spaced along the bracket. A housing defines an air intake opening and an air outlet opening and further defines, on each of two opposing sides thereof, a pair of tang receiving recesses spaced for alignment with and engagement by the tangs. A fan assembly, including a propeller assembly and a motor connected thereto, is mounted in the housing. Once the mounting brackets are connected to ceiling joists and positioned on opposite sides of an opening in a ceiling, the housing may be raised up into the opening such that the recesses in the housing are engaged by the tangs.
