AURA SOLAR ATTIC FAN
uses both solar and wind power
for Energy Savings
|
|
|
|
 |
|
|
 |
|
|
The Aura Solar Attic Fan uses both solar and wind power for optimum ventilation performance both day and night. Other solar powered attic fans do not move air passively but the Aura Solar Fan does, just like a roof turbine ventilator (Whirly-Bird) but with no moving parts. Exhausting air passively (driven by wind) also removes hot air from the attic on summer evenings and cloudy days, thus lowering attic temperatures and reducing air conditioning loads. |

|
|
- The panel wattage is oversized to the fans at a rate of 2 to 1
- This results in a CFM production of angles up to 80 degrees
- Quiet operation
- Compact design
- All aluminum construction
- Exhausts air continuously even after the sun sets or on cloudy days
- Aerodynamic internal cone increases performance
- Negligible roof loading
- Adaptable with all types of roofing materials
- No curb required
- Removeable head for easy maintenance
- Works 24/7
- Louver design passed Dade County Tests
