4-Inch Aura Solar Attic Fan | Model ASF-4-C2 | 91 CFM
The 4-inch Aura Solar Attic Fan is 4 inches in diameter and has a 2-inch tall collar. The model ASF-4-C2 exhausts air at 91 CFM. All 4-inch solar attic fans have a standard 10-inch x 10-inch square flange.
Benefits:
- Solar fan reaches 91 CFM for attic ventilation
- Keeps your home comfortable and energy-efficient
- Works passively with the wind when there is no sunlight
- Inner louvers prevent insects and animals from entering the vent
- Round aerodynamic design can withstand 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 7/12 in all climate zones. However, a simple modification can allow the solar attic fan to be installed on a 12/12 pitch in all climate zones.
The Aura Solar 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.
How it works:
The Aura Solar 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.
The Aura Solar Attic Fan will continuously exhaust air without the sun (evenings and cloudy days) because it works passively due to the Venturi Effect. When the wind blows against the outer louvers, this creates a vortex of air within the head, which creates an upward draft that allows air to flow out of the attic.
The 1/8-inch louvers on all sides prevent rain, snow, insects, and animals from entering inside the fan.
