A ceiling mounted fan ventilation device moves a fresh inflow of air from within a room such as a garage to said attic thereof in an effective manner in order to mitigate the climatic effects on the room due to adverse ambient conditions. The device is not only capable of moderating the temperature of the room, but also augments the existing ventilation system for the attic enclosure. The device may utilize the existing hole of an attic access means such as a disappearing stairway or scuttle hole thus negating the need for extensive modifications to an existing ceiling structure. Alternatively, a method is disclosed herein whereby the fan ventilation device may be mounted directly to the ceiling portion of the room. The device may be implemented in any type of room wherein it is desirous to maintain a fresh flow of air therethrough.
