This is a second-generation Smart Solar Attic Fan Pro, designed for roof ventilation. It is equipped with a powerful 50W solar panel. The fan delivers up to 2850 CFM of airflow for effective cooling. It effectively cools and dehumidifies rooms up to 4,000 square feet. Ideal for various spaces including attics, factory buildings, garages, warehouses, barns, sheds, grain storage facilities, greenhouses, and chicken coops. Features an upgraded, more efficient rare earth permanent magnet brushless DC motor. Designed to operate even on cloudy days with as little as 1W of solar power. The fan blades are engineered using advanced fluid dynamics software for enhanced performance. This model boosts solar power output by 20% and increases CFM by over 50% compared to the previous generation. The solar panel offers continuous horizontal angle adjustment from -45° to +45° for optimal sun exposure. It also provides vertical angle adjustment from 0° to 60° to maximize power generation efficiency regardless of roof orientation. A built-in temperature controller allows the fan to activate automatically between 50–104℉. The thermostat function can be turned off for continuous fan operation whenever power is available. An interface is included for connecting an external wall switch, providing manual control options. It features a DC12V external power socket, compatible with an AC adapter or energy storage battery for night operation.
