Product Overview

Active Ventilation Products Aura Solar Attic Fan exhausts air continuously by using solar and wind power for optimum ventilation performance. Model ASF-12-C2-BR 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.

Customer Reviews

740 CFM Brown Powder Coated 10 Watt Solar Powered 12 in. Dia. Roof Mounted Attic Exhaust Fan is rated 3.8 out of 5 by 10.
Rated 5 out of 5 by from 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!!!

Rated 5 out of 5 by from Great Product !! The two fans I purchased lowered the heat in my attic. Making the inside of my home much cooler, resulting in a lower electric bill. I received exactly what I ordered, and the fans were delivered earlier than promised.

Rated 4 out of 5 by from Just installed today and was fairly easy. We just installed today and was fairly easy to do. As I was handing to my husband the small fans were already running. It is cloudy today, but they were still running. If they do this well on a cloudy day I am sure they will perform as expected.

Rated 1 out of 5 by from 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.......

Rated 3 out of 5 by from Simple design, functional Easy to install, and works in direct sun light. But the fans have no shroud around them making it not as good as it could be,causing the Suction to not be as effective.

Rated 5 out of 5 by from Great Product Our roofer said as soon as he took the vents out of the box the fans kicked on.Very quite and I can tell a big difference up stairs.

Rated 4 out of 5 by from Decent Device I installed this in my garage due to extreme heat in there during the summer. Like other reviews I read before buying this product, I found it to be an easy, straight forward installation. The vent fans worked right out of the box as soon as the sunlight hit the panel. Not all of the fans come on every day depending on quality of sunlight. Sometimes only the two large ones come on if it's cloudy. None come on when it's really cloudy. But it works perfectly at the moment. Can't say how it works keeping my garage cooler in the summer until next year, but I am happy with my purchase.

Rated 2 out of 5 by from 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.
