AURA SOLAR ATTIC FAN
The Aura Solar Attic Fan uses both solar and wind power, for an optimum ventilation performance both day and night. Other solar powered attic fans do not move air passively, but the Aura Solar Attic Fan does, just like a roof turbine ventilator, but with no moving parts.

- The Aura Solar Attic Fan's top panel (see figure C on bottom of page) is positioned to catch sunlight.
- When the Aura Solar Attic Fan is not operating, which can occur on cloudy days as well as evenings, the Aura Solar Attic Fan will still ventilate passively like a roof turbine ventilator (Whirly-Bird) but with no moving parts.

Besides having a powerful solar fan, which ventilates dynamically on hot summer days, this roof vent also ventilates like a roof turbine ventilator (Whirly-Bird) but with no moving parts. This is accomplished by its patented louver design.
Moving air passively (driven by wind) also eliminates hot air on hot summer evenings, thus effectively lowering attic temperatures 24/7 (see chart at right for passive CFM air flow).
