8 Inch Aura Attic Fan | AF-8-C12 | 250 CFM

The 8 inch Aura Attic Fan is 8 inches in diameter and has a 12 inch tall collar. The model number is AF-8-C12 and exhausts air out at 250 CFM. All 8 inch gravity fans come with a standard 13″ x 13″ square flange.


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 in and out of the vent.

This Attic Fan is also available with an optional Shut-Off Switch, Thermostat, and Humidistat (THSOS).

Motor Type: Shaded Pole C – Frame

With 1/55 horsepower and 250 CFM, this 8 inch vent is perfect for ventilating smaller attic spaces.

How it works:

Even when the motor is off, the attic fan will still ventilate passively. In other words, even the smallest breeze can create exhaust ventilation to draw air out of the fan.

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 an 8 inch attic fan produces 185 CFM of air exhaust for attic ventilation.
