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.
Expected snow and rain in your region and the pitch of the roof are the key consideration when choosing the height of the collar of your roof vents. Zones 1 and 2 are not expected to sustain significant snow packs, while zones 3-7 are likely to experience snow, possibly for weeks or months. Vent collars under 4 inches are inappropriate for flat (0/12 pitch) roofs because even heavy rain can splash water into a shorter vent.
Active Ventilation Products Aura Ventilator is our optimum exhaust attic ventilation product line that has a patented engineered design to create CFM (Cubic Feet per Minute) of air flow with no moving parts. It is an excellent choice to exhaust attic heat in the summer to reduce hot attic temperatures. And, to exhaust moisture in the winter to keep the attic dry and cool to preserve attic insulation and prevent ice dams. The Aura Ventilation product line is made of durable rust free aluminum. Model AV-12-C2 is made up of 3 components: the vent head, collar and flange. Model AV-12-C2 is a 12 in. Dia. vent with a 2 in. collar height and 18 in. x 18 in. sq. flange. It has 113 sq. in. of Net Free Air Space. Its low profile is best used for a sloped roof. When air moves against the louvers of the outer cylinder it is directed to create a circular airflow. The louvers of the inner cylinder face in the same direction as the air movement created by the outside cylinder. This air movement creates a venturi effect which produces a vacuum or negative pressure to pull air from within the attic space. The vent head has a flat one piece spun lid that prevents rain and snow from entering the vent verses the turbine vent which is open to the sky and allows rain water to enter in no wind conditions. 5 year warranty.
