Aluminium Automatic Roof Turbo Ventilator An aluminum automatic roof turbo ventilator is a device that is designed to regulate the temperature and air quality in a building by removing stale and hot air and replacing it with fresh air. It is typically installed on the roof of a building and is powered by the wind, which causes the turbine to spin and draw air out of the building. The aluminum construction of the ventilator is ideal for use in harsh outdoor conditions, as it is lightweight, durable, and resistant to corrosion. The automatic function of the ventilator means that it does not require any external power source to operate, making it an environmentally friendly option.
