36-inch Aura Gravity Ventilator with Curb Mount Flange | Model AV-36-C6-CMF
The 36-inch Aura Gravity Ventilator with Curb Mount Flange is 36 inches in diameter and has a 6-inch tall collar. The model AV-36-C6-CMF has 1,017 inches of Net Free Area (NFA). All 36-inch gravity ventilators have a standard 40" x 40" square curb mount flange.
Benefits:
- Energy efficient
- Removes heat from the attic in the summer and moisture in the winter
- Inner louvers prevent insects and animals from entering the vent
- Round aerodynamic design can withstand harsh weather and wind forces beyond 200 mph
- The curb mount flange allows for easy access to the attic or duct below
- Noiseless – does not require electricity to exhaust air
Installation: On a roof curb
This roof vent has a curb mount flange, allowing easy installation on AVP's prefabricated roof curbs or any other square roof curb measuring 39 7/8 inches x 39 7/8 inches. If the curb is to be covered in roofing material, then the curb should measure 39 1/2 inches x 39 1/2 inches.
The 36-inch Aura Gravity Vents with curb mount flange are compatible with AVP's roof curbs in heights 8-inch- 12-inch- and 18-inch tall roof curbs
The 36-inch Aura Gravity Vents with curb mount flange are compatible with AVP's insulated roof curbs in heights 8-inch- 12-inch- and 18-inch tall roof curbs.
How it Operates:
The Aura Gravity Ventilator works like a roof turbine with no moving parts.
Aura vents rely on the Venturi Effect, which occurs when the wind blows against the outer louvers to create an upward draft. As a result, air is forced to flow out of the vent, removing heat from the attic in the summer and moisture in the winter. This allows for year-round ventilation on low-slope or flat roofs.
Even the slightest breeze can create exhaust ventilation to draw air out of the gravity vent. Therefore, wind speeds of 11 mph for a 36-inch Gravity Ventilator produce 2,538 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. They are certified by the Texas Department of Insurance and Florida State Approved.
