The Aura Gravity Retrofit Vent models are available in an array of sizes.
This Vent is a perfect replacement for "Whirlybirds" Roof Wind Turbines which frequently stop because of corrosion. The Aura Gravity Vent Retrofit does not need to spin in order to provide excellent ventilation. Instead, it pulls hot air with its louvers because of the Venturi Effect. These vertical louvers continually exhausts air with no moving parts, while preventing rain and snow from entering. The vertical louvers also keep out insects and animals allowing for optimal air flow. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.
The Aura Gravity Vent removes hot air in the summer and moisture from the attic in the winter to provide optimal ventilation. The Retrofit Vent head will fit over an existing base of the same diameter. This allows for quick and easy installation. Upgrade and make your roof ventilation maintenance free.
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. For any questions please email [email protected] or call at 1-800-ROOFVENT.
