Aura Vent 

The Aura Vent's patented louver design creates the Venturi Effect. This is accomplished when wind passes through the louvers of the Aura Vent, causing the air to spin, thus creating suction. This drawing ability exhausts out moisture and excessive heat from the attic. On days when there is very little wind, the Aura Vent is still effective because it utilizes the stack effect, which is created by hot air as it rises.

 

The Aura Ventilator uses minimal wind power and no moving parts. The wind enters the unit through a set of exterior vertical louvers, producing the necessary vacuum to extract excess moisture through a second set of interior louvers.

    

 

As demonstrated from the view below, air enters the vent from the front (left side of diagram), passing through the exterior louvers into the inner chamber, where it circulates and picks up speed. This in turn creates a vacuum which draws up the warm vapors from beneath the vent into the middle section. These vapors enter the inner chamber through the interior louvers and circulate together with the air which had entered from outside, until they both forcefully exit through the back of the vent (the right side of the diagram).

Aura-D Vent Data Sheet

 

Note: The Aura Ventilator can be installed on steeper pitch roofs, up to 90 degrees. A modification is available at no extra charge. The stock version of the AV cannot remain rain resistant above the roof pitch listed above for that model.

 

R*: Available in Round Flange only

 

1To install the Aura Ventilator on steeper pitches up to a 90 degree angle, a modification is available.

 

2With equal soffit, gable or other inlet vents, 'Pop Vents' (inlet vents) are available.

 

3This chart is based upon the 1/300 rule. One square foot of ventilation on top for every 600 square feet of floor. 50% exhaust, 50% intake.
