Solar Roof Vent Fan 12-Inch with 40W Dual Power and 1200 CFM, Attic Exhaust Fan and Solar Ventilator with 3-Speed Remote and Auto Start, Black

Your attic is cooking in the summer, and that heat is costing you money. This 12-inch solar roof vent fan uses free solar power to exhaust hot air and moisture, keeping your attic cooler and your AC bill lower. The 40W monocrystalline solar panel and MPPT controller maximize power capture, and the powerful DC brushless motor delivers up to 1200 CFM of airflow. The dual power supply system automatically switches to AC power on cloudy days, so your attic exhaust fan never stops working. The 3-speed remote and built-in temperature sensor (auto starts at 25°C) give you full control. This solar ventilator runs at ≤45dB, so it's quiet enough for residential use.<br> • Color: Black<br> • Material: Metal + Plastic<br> • Dimensions: 12-inch fan<br> • Features: 40W monocrystalline solar panel, MPPT controller, 1200 CFM airflow, dual power supply (solar + AC), 3-speed remote, auto start at 25°C, ≤45dB noise, adjustable solar bracket<br> • Intended Use: Attic ventilation, roof exhaust fan, greenhouse ventilation, garage cooling, storage shed ventilation<br> • Assembly Required: Yes (mounting)<br> • Package Count: 1
