The Aura Gravity Retrofit Ventilator is an ideal alternative for an outdated roof turbine. The Aura Gravity Vent operates on the principle of the Venturi Effect. When the wind blows against the outer louvers of the vent, it creates an upward draft, allowing air to flow out freely. Even the gentlest breeze can create exhaust ventilation. The Aura Gravity Ventilator also leverages the Stack Effect to enhance roof ventilation.
