Gravity Vent Retrofit models available in an array of sizes

A perfect replacement for (“Whirlybirds”) Roof Wind Turbines which frequently slow down or stop turning all together because of corrosion, damage, or just wear and tear. The Aura Gravity Vent Retrofit does not need to spin in order to provide excellent ventilation. The Aura Gravity Ventilator pulls hot air with its long louvers utilizing the Venturi Effect. These vertical louvers also prevent rain and snow from entering. The Aura Gravity Ventilator will last as long as the roof itself and will always work like new, unlike the worn out roof turbines they replace.

Upgrade and make your roof ventilation maintenance free!

Easy to install, Aura Gravity Vents do not need to be leveled or balanced like a old roof turbines do.

Roof turbine parts wear out, even if they are balanced perfectly. If a roof turbine is making noise, it is slowing down because it is wearing out. When it slows down, it is likely to start allowing rain and snow into the attic.
