20 Inch Aura Attic Fan | AF-20-C8 | 3,300 CFM

The 20 inch Aura Attic Fan is 20 inches in diameter and has an 8 inch tall collar. The model number is AF-20-C8 and exhausts air out at 3,300 CFM. All 20 inch gravity fans come with a standard 26″ x 26″ square flange.

Installation:

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: Open Ventilation

With 3/4 horsepower and 3,300 CFM, this 20 inch vent is perfect for ventilating attic spaces or plenums.

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 a 20 inch attic fan produces 881 CFM of air exhaust for attic ventilation.
