4-inch Aura Solar Attic Fan | Model ASF-4-C8 | 91 CFM
The 4-inch Aura Solar Attic Fan is 4 inches in diameter and has an 8-inch tall collar. The model ASF-4-C8 exhausts air at 91 CFM. All 4-inch solar attic fans have a standard 10-inch x 10-inch square flange.
Benefits:
- Keeps your home comfortable and energy-efficient
- The fan runs virtually silent at 91cfm
- 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 can withstand harsh weather
Installation:
Exhaust fans with a collar height of 8 inches or greater are typically used for low-slope or flat-roof ventilation. However, if installed less than 4 feet from the peak, this fan can be used on a 0/12 to 5/12 pitch roof in climate zones 1-6.
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 and cool during the winter will preserve attic insulation and prevent ice dams.
How it works:
The Aura Solar Fan uses both solar and wind power to power the ventilator. However, the fan only works with solar power when in bright, direct sunlight on south-facing roofs.
However, it exhausts air continuously, even without the sun. 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, 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.
