Abstract
An air-exhausting apparatus, device, method of assembly and use for an attic and rooftop fan, which prevents water intrusion into the housing. The fan can include a tubular base having a bottom side mounted on a roof of a room, and an upper end portion converging toward a top side of the base. A coupling sleeve unit has a first coupling end portion sleeved fixedly on the base and cooperating with the base to define an annular draining passage therebetween, and a second coupling end portion opposite to the first coupling end portion. A fan unit is mounted in the coupling sleeve unit, and is operable so as to exhaust air outwardly of the room via air holes in the second coupling end portion of the coupling sleeve unit. A cover unit includes a cover body disposed on the second coupling end portion of the coupling sleeve unit, and a supporting frame interconnecting fixedly the cover body and the coupling sleeve unit. Wear and/or sound absorbers can also be included.
