Product Details

Active Ventilation Products Aura Solar Attic Fan exhausts air continuously by using solar and wind power for optimum ventilation performance. Model ASF-12-C2-BL has a 10-Watt solar panel providing energy to 4 EC fans on sunny days to increase the CFM (cubic feet per minute) of 740 of air flow performance. It is an excellent choice to exhaust attic heat in the summer to reduce hot attic temperatures. It will also exhaust moisture in the winter to keep the attic dry and cool to preserve attic insulation and prevent ice dams. The Aura Solar Attic Fan will produce 310 CFM at 11 mph without the solar powered fans through its patented engineered design with no moving parts. The attic fan is made of durable rust free aluminum and has 5 manufactured components: the vent head, 4 - EC fans, 1 - solar panel, vent collar and square flange. It has a 12 in. Dia throat opening with a 2 in. collar height and a 18 in. x 18 in. square flange. The vent head has three concentric cylinders with slotted vertical louvers. When air moves against the louvers of the outer and middle cylinders it is directed to create a circular airflow. The louvers of the inner cylinder face in the same direction as the air movement created by the outside cylinder. This air movement creates a Venturi effect which produces a vacuum or negative pressure to pull air from within the attic space.
  • No wiring or batteries required, operates on solar energy
  • Does not require electricity to exhaust air from attics spaces
  • Solar panel operates at 12-Volt
  • Solar panel is manufactured tempered glass; rugged design to withstand high wind pressure, hail and snow load; providing exceptional panel rigidity

  • Vent head has a flat one piece spun cap that prevents rain and snow from entering
  • Pitch capacity range: 3/12 to 12/12
  • Net free air: 113 sq. in. (0.78 sq. ft.)

            I wish I had bought 2!!
            We love this fan...we just had a new roof put on and all of the roofers were ecstatic that they didn't have to mess with any wiring when installing this. They actually pulled an old vent off of my roof and installed it right overtop of the cut-out. The guy that installed it said it kicked on as he was nailing it to the roof!!!

            This is a good buy!
            Easy to install, and dropped the attic temperature in my garage by 20 degrees.

              worst ever
              This fan was suppose pull 740 cfm, 4 three inch fans, can't pull that much. Took it outside to see how it would work before cutting hole in roof, glad I did couldn't feel no air movement. It's made of thin sheet metal, base is very flimsy. If you buy, put it in the sun, before cutting roof.......

              Cheaply made
              Flimsy construction. The 'fan' is actually a few cheap plastic fans, like the kind used inside a computer. The airflow is minimal even in full sunlight.
