12 in. Diameter Aura Vent Retrofit, Roof Exhaust Vent, Active Ventilation

Description

The 12 inch Aura Gravity Retrofit Vent | Model AV-12-RF
The
12 inch Aura Gravity Retrofit Vent
is for replacing existing attic vents. The AV-12-RF is 12 inches in diameter and has 113 inches of Net Free Area (NFA).
This roof vent will fit over an existing base of the same diameter. It is a perfect replacement for turbine vent heads. Turbine vents frequently stop turning entirely due to corrosion. However, our Gravity Retrofits are made of durable rust-free aluminum.
Installation:
The Aura Gravity Retrofits will fit over an existing base of the same diameter. This allows for easy installation without damaging the roofing material. The vent removes heat from the attic in the summer and moisture in the winter allowing for proper ventilation. This retrofit comes in an array of sizes to fit all roofing needs.
How it works
:
The Aura Gravity Ventilator works like a
roof turbine but with no moving parts
.
Aura Gravity Ventilators rely on the
Venturi Effect
when the wind blows against the outer louvers. As a result, this creates an upward draft allowing air to freely flow in and out of the vent.
Even the smallest breeze can create exhaust ventilation to draw air out of the gravity vent. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph. This is much more efficient compared to a typical wind turbine vent, which is open to the sky; Thus allowing rain and snow to get inside when it is not in motion.
