- 2000 CFM Powerful Ventilation – This 40W solar attic fan delivers up to 2000 CFM airflow and helps ventilate attic spaces up to 2500 sq.ft. Designed to exhaust trapped heat, moisture, and stale air, it is ideal for attics, garages, sheds, workshops, greenhouses, and other enclosed spaces that need better air circulation.
- Solar & AC Hybrid for Day/Night Operation – The solar roof exhaust fan works with a 40W monocrystalline solar panel and included AC/DC adapter. Use solar power for energy-saving ventilation during sunny hours, while the adapter helps support operation when sunlight is weak or unavailable, making ventilation more consistent throughout the day and night.
- Two Modes & MPPT Controller – Mode I, Energy Saving Mode, adjusts the fan’s airflow based on available sunlight, while the AC/DC adapter can be used as supplemental power for steadier airflow. Mode II, Performance Mode, lets you adjust the roof ventilation fan from speed 1 to 4 with the control knob for stronger airflow. AC/DC adapter is required for Mode II.
- Adjustable Thermostat Control – Set your preferred operating temperature from 68°F to 113°F with the independent controller. The fan starts when the attic reaches the selected temperature and helps remove hot air automatically. The thermostat can also be disabled when continuous solar-powered ventilation is preferred.
- Multi-Angle Panel & Roof Kit – The solar panel can be adjusted from 0° to 70° horizontally and vertically to capture better sunlight throughout the day. Built for roof-mounted ventilation, this IP65 waterproof solar attic fan includes the solar roof fan, controller, AC/DC adapter, mounting template, brackets, screws, user manual, and service card for installation.
