The Round Back Solar Roof Exhaust Fan runs off direct sunlight. Customers may want to install several solar fans for their roof, at the same time just like if the products were regular static roof vents. Solar roof exhaust fans, mechanically remove hot trapped attic air in the summer and moist air in the winter. Mechanical ventilation will make the home more energy efficient and will make the family more comfortable. Please note that the fan will not run during the evening; however the solar roof exhaust fan will continue to ventilate passively during the evening. The design of the solar fan will prevent rain, snow, insects & animals from entering the attic cavity.

The solar roof exhaust housing is 8 inches in diameter and is built with a 2 inch tall (clearance) collar. The model RBSF-8-C2 has square base (flange) that is 13 inches by 13 inches. Engineered for all weather zones 1 through 8 as long as the roof pitch is 4/12 or greater and the exhaust fan is installed no lower than 18 inches from the peak of the roof.  This solar fans can be installed down to 3 feet from the peak in climate zones 1 – 4 as long as the roof pitch is 3/12 or greater. RBSF-8-C2 is best used for a 3/12 to 12/12 roof pitch. Match the color of your fan with the color of your roof. There are many colors to choose from.
