The Aura Gravity Roof Ventilator with curb mount flange shown above, vigorously removes heat from the attic in the summer and moisture from the attic in the winter. How does it do this? The Aura Gravity Ventilator functions much like a spinning roof turbine, but does not need to spin in order to work. Functioning with no moving parts the Aura Gravity Ventilator pulls hot attic air every time the wind blows. This is done by a phenomenon called the “Venturi Effect”. Roof Ventilation is also accomplished by other means, like the “The Stack Effect” for example. This is when hot air rising is at play. As the hot air rises, it accelerates to the outside. This powerful dynamic ventilates the attic constantly.
Rain and snow will not get past these Gravity Ventilators louvers nor will birds, insects or animals.
Engineered and certified for both flat roof ventilation and steep slope ventilation, the Aura Gravity Ventilator is available for both residential and commercial buildings. UL listed this gravity roof vent is rated to withstand wind pressures of over 50 PSF, which is equivalent to wind speeds exceeding 200 mph! The Aura Gravity Ventilator is also Florida State, Texas Department of Insurance Listed and conforms to CAL FIRE standards. Available with standard flashing or curb mount flashing the Aura Gravity Ventilators can be installed onto asphalt shingle roofs, membrane roofs and on roof curbs alike.

Gravity vents can be fitted with a tail pipe (adapter to a duct) if ventilating a duct system is required. Roof vents with tail pipes are great for bathroom or range hood exhaust (for example).
All our roof vents, curb mount flanges and roof curbs are fabricated from durable and lightweight aluminum, and so WILL NEVER RUST!
Colors are available so that your vent matches the color of your roof.
