Dimensions

Basic dimensions of the Aura Solar 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:

16 in.
40.6 cm.

Outside Diameter:

21 in.
53.3 cm.

Square Flange (side length):

20 in.
50.8 cm.

Height of Head:

8 in.
20.3 cm.

Collar Height:

12 in.
30.5 cm.

Height of Flange:

2 in.
5.1 cm.

Total Height with Collar and Flange:

23.25 in.
59.1 cm.

Louvers

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):

5.5 in.
14 cm.

Louver Height (outside):

5.5 in.
14 cm.

Size of opening btwn blades (inside):

0.125 in.
0.3 cm.

Size of opening btwn blades (outside):

0.25 in.
0.6 cm.

Roof Pitch

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.

The Venturi effect 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

This is a premium exhaust fan, with a flange for easy mounting onto a roof curb, ideal for flat industrial roofs. Even when the power is off, it is activated by even a small breeze to forcefully evacuate air using the Venturi effect. All Aura Vents and fans use louver technology to keep your property safe, comfortable, and energy efficient.
