20W Solar Attic Fan (Black/20W)

⭐ Key Features

•【High Efficiency Solar Roof Vent Fan】The HONGUAN Solar Attic Fan comes equipped with 20W 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.

•【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.

•【Versatile Applications】With a maximum cooling capacity of up to 1,100 sq. ft., this solar roof fan is perfect for a wide range of applications. It works well in smaller spaces like homes, where it quickly cools indoor temperatures and reduces air conditioning load, while also being ideal for larger areas such as greenhouses, warehouses, garages, factories, and farms.
