The Aura Gravity Fan exhausts air continuously even when the motor is off. This attic fan works passively because of the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow out.
This Attic Fan is also available with an optional Shut-Off Switch, Thermostat, and Humidistat (THSOS).
The 16 inch attic fan will remove heat from the attic during the summer. In addition, it will also remove moisture during the winter.
This movement of air is proportional to the wind speed and is measured in cubic feet per minute (CFM). Therefore, wind speeds of 11 mph for a 16 inch attic fan produces 497 CFM of air exhaust for attic ventilation.
