The 18-inch Aura Solar Attic Fan is 18 inches in diameter and has a 2-inch tall collar. The model ASF-18-C2 exhausts air out at 1,740 CFM. All 18-inch solar attic fans have a standard 23" x 23" square flange.
Benefits:
- Keeps your home or building comfortable and energy-efficient
- The fan runs virtually silent at 1,740 cfm
- Fan gets electricity from direct sunlight
- Works passively with the wind when there is no sunlight
- Inner louvers prevent insects and animals from entering the vent
- Round aerodynamic design withstands harsh weather
Installation:
If installed no more than 2 feet from the peak, this fan can be installed on a roof with a pitch of 3/12 to 5/12 in all climate zones. However, with modification, it can be installed on a 12/12 pitch in all climate zones.
The Aura Solar Attic Fan is ideal for ventilating steep-slope roofs. It removes heat during the summer and moisture during the winter to provide ventilation all year. Keeping the attic dry during the winter will preserve attic insulation and prevent ice dams.
18-inch-diameter fans are considered commercial size and should be used in commercial settings. For those looking to ventilate their homes, please view roof vents with a smaller diameter.
How it works:
The Aura Solar Attic Fan uses direct sunlight to power its fan. The panel above needs bright, uninterrupted sunlight, preferably on a south-facing roof. Never point the solar panel in a northern direction, or it will not work.
Solar attic fans exhaust air continuously, even without the sun (on cloudy days and evenings). They work passively due to the Venturi Effect. When the wind blows against the outer louvers, this creates a vortex of air within the head, creating an upward draft that allows air to flow out of the vent.
The 1/8-inch louvers prevent rain, snow, insects, and animals from entering inside the fan.
