Installation:
Aura Solar Attic Fans are a perfect replacement fan for Roof Wind Turbines, which frequently stop working because of corrosion. The Solar Attic Fan has a high-efficiency fan to provide excellent ventilation year-round. It exhausts heat in the summer and moisture in the winter.
The Solar Attic Fan also works passively using the Venturi Effect. When the wind blows against the outer louvers, an upward draft is created, allowing air to flow freely out of the attic.
How it works:
Working off direct sunlight, the Solar Attic Fan Retrofit's solar panel should not be facing north. The more south in direction, the better, as long as there is no shade from trees or other obstructions.
The vertical louvers continually exhaust air while preventing rain and snow from entering. The vertical louvers also keep out insects and animals, allowing for optimal airflow. In addition, the round design is aerodynamic to withstand wind speeds beyond 200 mph.
Roof turbine parts wear out, even if the vent is balanced perfectly. If a roof turbine makes noise, it slows down because it is worn out. It will likely allow rain and snow into the attic when it slows down. The Aura Solar Retrofit will prevent rain and snow from entering the attic for the life of the roof.
