The 12 inch Aura Solar Attic Fan is 12 inches in diameter and has an 8 inch tall collar. The model ASF-12-C8 exhausts air out at 740 CFM. All 12 inch solar gravity fans come with a standard 17″ x 17″ square flange.


  • 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


Exhaust fans with a collar height of 8 inches or greater are typically for low slope or flat roof ventilation. However, if installed less than 4 feet from the peak, this fan can go 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 will remove 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 to power the ventilator. 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. As a result, creating an upward draft which allows air to flow out of the vent.

The 1/8 inch louvers prevent rain, snow, insects, and animals from entering inside the fan.
