Active Ventilation Products Aura Solar Attic Fan exhausts air continuously by using solar and wind power for optimum ventilation performance. Model ASF-14-C2-BR has a 15- Watt solar panel providing energy to 4 EC fans on sunny days to increase the CFM (cubic feet per minute) of 1007 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 360 CFM at 11 mph without the solar powered fans through its patented engineered design with no moving parts. The attic fan is made of corrosion resistant aluminum and has 5 manufactured components: the vent head， 4 - EC fans， 1 - solar panel， vent collar and square flange. It has a 14 in. Dia throat opening with a 2 in. collar height and a 19 in. x 19 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

Quiet fan operation; designed to run up to 40，000 life hours per fan

Inner vertical louvers will keep insects， birds and squirrels from entering the vent allowing optimal air flow and no maintenance

Round aerodynamic design can with stand harsh weather and wind forces of up to 200 mph

Pitch capacity range: 3/12 to 12/12

Net free air: 144 sq. in. (1.00 sq. ft.)

Ventilation rule 1:300: one unit per 600 sq. ft. of attic space (maximum up to 900 sq. ft.)

Brown powder coating finish is significantly greater at resisting scratching， chipping， and oxidation

Covered vent head is a flat one piece spun cap that prevents rain and snow from entering

Removable vent head for easy access

Exhausts air continuously even after the sun sets or on cloudy days

Works 24/7， helps to reduce energy costs

1007 CFM at 0.1 SP
