Product Description
Solar Powered Exhaust Fan, 40W 24V Solar Panel with Brushless Fan for Shed Ventilation,
Solar Fans for Outside, Greenhouse, Home, Chicken Coop, Outdoor
The working principle of a solar ventilation fan is to convert solar energy into electrical energy by using solar panels, which drives the motor to operate and rotates the fan blades, thus generating air flow and achieving the function of ventilation.
A solar ventilation fan usually consists of parts such as solar panels, a motor, fan blades, and a bracket. The solar panel is the core component of the solar ventilation fan as it can convert solar energy into electrical energy. The motor then converts electrical energy into mechanical energy to drive the rotation of the fan blades. The rotation of the fan blades can generate air flow, thus achieving the function of ventilation.
Solar ventilation fans have the advantages of energy conservation, environmental protection, convenient installation, and no need for wiring. They are suitable for various places such as homes, offices, factories, warehouses, etc.
Solar Powered Roof Ventilation Fan
A compact axial flow solar ventilation fan, taking advantage of natural free solar power, making highly efficient ventilation by DC motor.
As an energy-saving green ventilation solution for a healthy & comfortable environment!
The solar panel captures sunlight and converts it into electricity to power the fan motor. The Solar Attic Fan works in conjunction with your existing passive vents (soffit or gable) to pull hot air and moisture out of your attic. Keeping your attic ventilated extends the life of your roof, reduces vapor build-up, and prevents mold growth. In the summer, it helps keep your attic cooler reducing your air conditioning costs. In the winter, it prevents ice damming.
Installing such an auto-running solar fan would pump out interior stale, heat air to improve indoor air circulation, reduce moisture & harmful mildew, extend the roofing lifespan, reduce the load on the air-conditioner and HVAC system in Summer, and prevent ice dam in Winter.
1. Patented Air Draft Design, for a Higher Efficiency!
Our patent-designed wind guide cone with 24pcs turbine wind gride blades structure is adopted in this ventilatior. Following a 360-degree swirl ventilation mode and being free from outside airstream interference, it can work efficiently on sunny days to exhaust out the indoor heat &smell and not let any exterior air going in, so as to keep the living &working environment always clean& fresh. On rainy windy days, this air draft design can also efficiently prevent the rains or winds from flowing backward.
2. Most Advancing Technology for IP68 Motor
To assist our solar exhaust fans be working excellently also in special environments like greenhouse/water tanks where their surroundings are very humid, we've self-developed a brushless DC motor that is IP68 waterproof, and its quality can be guaranteed even by dipping it into water for tests!
3. Adjust Angle
Fan host fully assembled with solar panel, compact design all in one unit; Polycrystalline solar panel in high conversion efficiency, adjustable solar panel to better capture daily sunlight, for optimal solar exposure.
4. Durable Fan Case
Unibody fan case in strong galvanization steel, square flashing seamlessly connected with air duct; fan housing is rust-proof and finished with anti-UV powder coating, for both practical practical use and generous appearance.
Optional Round or Square Housing cap
