Where to Install:
If placed 2 feet or less from the roof peak, this roof vent can be installed in all climate zones. The Aura Gravity Vent is designed for a roof pitch of 3/12 to 7/12. However, a simple modification of this roof vent can be installed on a 12/12 roof pitch. See the installation guides for help installing.
The Aura Vent is ideal for ventilating steep-slope roofs. It removes heat during the summer and moisture during the winter to provide ventilation all year. Keeping the attic dry during the winter will preserve attic insulation and prevent ice dams.
How it Operates:
The Aura Gravity Ventilator works like a roof turbine with no moving parts.
Aura Gravity Ventilators rely on the Venturi Effect, which occurs when the wind blows against the outer louvers. This creates a spinning upward draft through the vent, allowing air to flow dynamically. Even the slightest breeze can create exhaust ventilation to draw out air from the attic.
The Aura Gravity Roof Vents are made of durable, rust-free aluminum. The vent head has a flat one-piece spun lid that prevents rain and snow from entering the vent. The round aerodynamic design can withstand harsh weather and wind forces beyond 200 mph. Therefore, wind speeds of 11 mph for an 8-inch Gravity Ventilator produce 185 CFM of air exhaust for attic ventilation.
The inner louvers of the roof vent prevent insects and animals from entering the attic. The louvers also allow the air to flow freely to the outside.
AVP’s Aura Gravity Vents are UL-listed, rated up to 50+ PSF or wind pressure above 200 MPH, and certified by the Texas Department of Insurance, Florida State Approved.
