  • UltraFl?® Technology:This proprietary design technology gives Attic Breeze solar attic fans the greatest CFM to watt efficiency rate. Maximum airflow is produced through the 14 inch, 5-wing aluminum fan blade with integrated balanced hub. When air hot attic air is drawn into the fan, the airflow stream is condensed through the fan housing, creating an increase in air density at the fan blade. This effect maximizes conversion efficiency, while consuming less energy!


  • Commercial Grade Monocrystalline Solar Panel:Attic Breeze's unique panel design features high-strength, impact resistant tempered glass construction, and performs with greater power output than panels with a polycrystalline or multicrystalline composition. This technology allows Attic Breeze fans to function efficiently at higher roof temperatures without the loss of rated power.


  • Breeze Mate™ Control System (Optional):This remote interface control system is an attractive option, and gives you the ability to communicate wirelessly through a Master Controller with Attic Breeze solar fans installed on your Breeze Mate™ network. For little additional cost, this puts ventilation preferences in your hands, and allows you to exercise total control over fan operation by customizing both temperature and humidity levels specific to the needs of your application.
