Ventilation equipment energy heavy-duty steel industrial ventilation fan self-driven solar roof heat exhaust fan. Ventilation equipment is an axial flow dc motor-driven exhaust fan powered by solar. With solar panels, it starts running once the sun shines. It needs no wire to grid electricity, but automatically running when there is sunlight. So it would make ventilation more efficient when the sunshine is stronger. That is exactly the time the roof cavity would accumulate heat, and you really need a solar roof exhaust fan to get the heat, stuffy air out of your house attic.
Besides, if you need this active solar-powered ventilator even run in sunless time, you could choose an optional power adapter or storage battery from us.

The Ventilation equipment is one kind of wind turbine, it is the mechanical energy that depends on the input, and improves the gas pressure side by side to send the gas. The circulating fan is widely used in the ventilation of greenhouse, greenhouse, livestock, and poultry house. Especially for the closed type barn moisture density, the air is easy to flow place, press the directional arrangement of relay ventilation, the damp heat airflow of the hovel more fully, the cooling effect is excellent. Is the ideal vertical, horizontal circulation airflow, ventilation cooling equipment.

This type of Ventilation equipment mainly composed of blades, motor, frame, protecting news, and supporting frames and shutters. The motor drive blades cause airflow and shutters can open and close automatically to keep the dust from entering. The major parts are made of galvanized steel sheets and stainless steel sheets.
