Basic dimensions of the Aura Fan 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.

Inside Diameter:

30 in.
76.2 cm.

Outside Diameter:

36 in.
91.4 cm.

Square Flange (side length):

40 in.
101.6 cm.

Height of Head:

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 patented “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.

Louver Height (inside):

9 in.
22.86 cm.

Louver Height (outside):

9 in.
22.86 cm.

Size of opening btwn blades (inside):

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.

When the Fan is OFF, the Venturi effect is stimulated by even small breezes creates a positive movement of air out of the vent without the need of any part of the vent to move. This movement of air is proportional to the wind speed, and can be measured in Cubic Feet per Minute or Cubic Meters per Minute.

Description

Aura Fan, Roof Mounted Exhaust Fan 8,000 cfm, 30″ diameter Roof Vent with a 8″ Collar Height and 37″ Square Flange

This attic fan / roof fan EXHAUSTS CONTINUOUSLY whether the electric motor is ON or OFF. When the fan is off, outside air moving against the Aura Ventilator causes the Venturi effect, thereby creating an exhaust. The exhaust is created without the use of electricity or moving parts. On the days when the fan is not needed, the Aura Vent will still operate passively; this increases the life of the motor since it is not in constant use. The Aura Fan Ventilator reduces energy consumption.

1/8th inch opening between the louver blades and all aluminum (“noncombustible”) material meets the requirements of California building code 706A.2 Vents to resist the intrusion of burning embers and flame through ventilation openings.
