Natural ventilation
Natural ventilator is a ventilating device that is driven by natural horizontal wind and vertical air flow formed by the temperature difference between indoor and outdoor. The scientifically designed blade can push it to rotate even with the breeze. When the turbine head rotates, it generates centrifugal force, which extracts hot air, smoke, humid gases and other exhaust gases in the space below the turbine head. As the exhaust gas is drawn out, a negative pressure zone is formed under the turbine head. Fresh air from the outside will flow into the negative pressure zone from the windows and doors, and the turbine head continuously rotates to achieve the purpose of ventilation, exhaust, and exhaust.
