This attic fan / roof fan EXHAUSTS CONTINUOUSLY whether the electric motor is ON or OFF. When the fan is off, outside air moving against the Aura Ventilator causes the Venturi effect, thereby creating an exhaust. The exhaust is created without the use of electricity or moving parts. On the days when the fan is not needed, the Aura Vent will still operate passively; this increases the life of the motor since it is not in constant use. The Aura Fan Ventilator reduces energy consumption.
1/8th inch opening between the louver blades and all aluminum (“noncombustible”) material meets the requirements of California building code 706A.2 Vents to resist the intrusion of burning embers and flame through ventilation openings.
