This Product is a non-powered turbine-type rooftop natural ventilator (commonly known as a stainless steel wind ball / non-powered vent cap). It relies on the dual driving forces of natural wind and thermal convection caused by indoor-outdoor temperature differences to rotate the turbine. By leveraging the centrifugal negative-pressure effect, it continuously extracts high-temperature exhaust gases, moisture, and odorous gases from workshops and buildings, all without electricity, zero energy consumption, and no operational noise.
