Roof Ventilation Turbo Charged

The Aura Gravity Vent is for replacing old roof turbines. The Aura Vent is made of aluminum therefore it will not rust over time. It also does not spin in order to create ventilation. The Aura Vent relies on the Venturi Effect. This occurs when wind blows against the outer louvers creating a vortex within the head. This will draw air up and out of the vent. The gravity ventilator also ventilates the roof through “The Stack Effect”. This is when hot air naturally rises out through the roof vents.

Old roof turbines spin in order to prevent rain from getting inside. AVP’s vents have a double louver design pressed together that is cut to 1/8 inch. This allows for optimal airflow while preventing rain, snow and wildlife from entering inside.

The Aura Gravity Ventilator removes heat from the attic in the summer and moisture in the winter. This allows for year-round ventilation. This air movement is proportional to the wind speed and measured in cubic feet per minute (CFM).

The Aura Gravity Ventilator works like a roof turbine but with no moving parts.

The Collar Height is the height of the neck of the vent.

The Gravity Ventilators come in an array of diameters and collar heights allowing for installation in any climate zone. See the Climate Zone Chart to determine the proper collar height for installation in your area. In other words, this vent can be used for both flat and steep sloped roofs. It has also been engineered to be used for both residential and commercial buildings. However, if you are looking to ventilate a duct, AVP offers roof vents with a tailpipe adapter. On the other hand, AVP also has Static Vents with curb mount flanges to be installed on roof curbs.

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.

How the Aura Gravity Ventilator works:

As you know by now the Aura Gravity Ventilator uses wind to help exhaust out hot attic air with no moving parts. Here is a deeper explanation of how this gravity ventilator accomplishes this function. To start, when wind enters the outer row of louvers, the angle of the louvers causes the wind to spin around the circumference of the gravity vent. Spinning air creates suction towards the center of the vent. This suction creates the necessary vacuum to extract out the heat and moisture from the attic. This function is demonstrated by the animation above. Airflow ratings were documented by Georgia Tech.
