740 CFM Mill Finish 10-Watt Solar Powered 12 in. Dia Roof Mounted Attic Exhaust Fan
$96.00
Active Ventilation Products Aura Solar Attic Fan exhausts air continuously by using solar and wind power for optimum ventilation performance. Model ASF-12-C2 has a 10-Watt solar panel providing energy to 4 EC fans on sunny days to increase the CFM (cubic feet per minute) of air flow performance to 740 CFM. 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, preserving attic insulation and preventing 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 3 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.”,”highlights”:[“Rust-resistant aluminum construction ensures durability”,”Operates on solar energy to eliminate need for electricity”,”Backed by a 5-year warranty”
