Enjoy a more comfortable home with the Air Vent attic ventilator fan. This gable-mountable fan fits conveniently into the corner of an attic. It is able to ventilate a space that is up to 1,500 square feet in size. It moves up to 1,050 cubic feet of air per minute. By pulling hot air out of the attic, this energy-efficient fan can lower the workload on the central air conditioning system. You can set a temperature control to trigger the fan to turn on automatically.
