The award winning U.S. Sunlight Sunfan^® Solar Attic Fan ventilates up to 2400 square feet of attic space with a single fan, requiring fewer fans to properly ventilate your attic space. The new, patent pending, Smooth-Air Deflector design in the shroud of the fan enhances the efficiency of air flow, resulting in increased ventilation performance by up to 30% over previous models powered entirely by free and abundant solar energy. The SunFan^® Solar Attic Fan effectively reduces attic heat buildup in the summer months and moisture in the winter months. In the summer, your attic can easily reach temperatures of 150F, resulting in a battle between the attic heat and your air conditioner. With 43% of air conditioning design load based on high attic temperatures frequently reaching 150F, reducing attic heat also reduces air conditioning run-time. In the winter months, the building materials in your attic can absorb up to 28 gallons of moisture, contributing to mold and mildew growth.
