Hon&Guan 25W Solar Attic Fan, 24/7 Smart Cooling for Up to 1300 Sq Ft

Why it's a great deal

• 【High Efficiency Solar Roof Vent Fan】The HONGUAN Solar Attic Fan comes equipped with both solar panel and AC adapter, giving you the flexibility to choose the power source based on the weather or time of day. With multiple adjustable fan speeds—up to 320 CFM—it delivers energy-saving, efficient cooling and ventilation to keep your indoor environment fresh and comfortable.

• 【24/7 Worktime with AC Adapter】Unlike other solar roof fans that rely solely on solar power, our roof fan includes an additional AC adapter to ensure stable operation at night or on cloudy days. It runs continuously 24/7, completely unaffected by weather or sunlight conditions, so your home stays cool and comfortable all day long.

• 【Efficient & Eco Solar Panel】This solar attic fan runs efficiently on the included 25W waterproof solar panel (17"*13") by day, helping you save significantly on electricity bills. The panel's angle can be adjusted freely during installation to capture maximum direct sunlight exposure based on your actual lighting conditions, thereby optimizing ventilation efficiency.

• 【Dual Operating Mode Options】I Eco Mode: Primarily powered by solar energy, while the AC adapter supplies just enough power to maintain the minimum fan speed. When solar power is sufficient, the fan speed increases proportionally with solar input. II Performance Mode: Connects to the AC adapter, offering 4 adjustable speed levels with stable and consistent airflow.

• 【Smart Temp Control】Equipped with a temperature probe for precise ambient temperature detection, the attic fan can automatically respond to temperature changes—smart control that lets you set it and forget it. The adjustable temperature range is 68–113°F. When the probe detects that the temperature has reached the set value, the fan automatically turns on; once the temperature drops below the set value, the fan shuts off.
