Basic dimensions of the Aura Vent and it’s identifying attributes. Primary identifying dimensions of vents and fans are the inside diameter of the Head, which equals the diameter of the hole being vented, and the height of the Collar which is the solid tube between the Head of the vent and the Flange which attaches to the roof.
Louvers are the vertical openings in the vent, which facilitates the flow of air, while keeping animals, insects, debris, and embers out. The combination of inner and outer Louvers on our signature “Aura” series of vents and fans are shaped to create a positive vacuum effect which draws air out of the vent, utilizing a physical principle known as the Venturi effect.
How much clearance (vent height) your roof vent needs depends on the pitch of your roof and the climate zone you live in. If you have a 4/12 roof pitch or greater, you can have a low profile vent (1” 2” tall collar) in all climate zones. At a 3/12 roof pitch you can have a 1” or 2” tall collar in zones 1, 2, 3. Having a 3/12 roof pitch in zones 4, 5, 6, 7, 8 you will need a 4” tall collar. For roof pitches 2/12 or less you will need a 4” tall collar in zones 1 & 2. You will need a 6 inch tall collar for zones 3, 4 and an 8” tall collar for zones 5 and 6. You will need an 11″ or 12” tall collar for zones 7 and 8. Bear in mind, you can always use taller collars for additional clearance in warmer zones, but you can’t use shorter collars in colder zones when dealing with low slope roofs. Custom collar heights are also available.

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 6 inch Aura Gravity Ventilator, produces 126 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.
