The 14 inch Aura Attic Fan is 14 inches in diameter and has a 12 inch tall collar. The model AF-14-C12 exhausts air out at 1,000 CFM. All 14 inch gravity fans come with a standard 19″ x 19″ square flange.
This fan is an attic exhaust fan. It has an all aluminum construction making it durable and long lasting.
With 1/8 horsepower and 1,000 CFM, this 14 inch attic fan is perfect for ventilating all attic spaces.
A collar height of 12 inches is for low slope or flat roof ventilation. However, if installed on the upper portion of the roof, this attic fan can go on a 0/12 to 5/12 pitch roof in all climate zones.
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 14 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 14 inch attic fan produces 360 CFM of air exhaust for attic ventilation.
