Aura Gravity Ventilators of 16 inch in diameter or larger are considered commercial sized. For those who are looking to ventilate their homes, they are encouraged to view roof vents that are smaller in diameter. Typically vents that are 14 inch in diameter or smaller are recommended.
To install vents for air exhaust the Aura Gravity Vents should be placed on the upper portion (no more than 3 feet down from the peak) of the roof. Roof vents of this size can go on a (2/12 warm climate only) 3/12 to 5/12 pitched roof. For roofs that are pitched at 6/12 or steeper, please notify the sales department when ordering your roof vents. All Aura Vents can be modified so they can be installed on a 12/12 pitch roof.
The Aura Gravity Ventilator works like a roof turbine but with no moving parts.
Aura Gravity ventilators rely on the Venturi Effect (the creation of an upward draft) when wind blows against the outer louvers.
Even the smallest breeze can create exhaust ventilation so that air is drawn out of the gravity vent. This movement of air is proportional to the wind speed, and is measured in cubic feet per minute (CFM). Wind speeds of 11 mph for a 16 inch Aura Gravity Ventilator, produces 497 cfm of air exhaust for attic ventilation.
Aura Gravity Vents are UL Listed and rated up to 50+ PSF or wind pressure above 200 MPH. Certified by Texas Department of Insurance, Florida State Approved & Conforms to the Standards of CALFIRE.
