A turbo ventilator for RCC (Reinforced Concrete Cement) structures is a mechanical device that utilizes wind energy to create natural ventilation by exhausting hot air and fumes from the interior of a building. It's often installed on the roof or upper part of the structure to promote air circulation and improve indoor air quality. The spinning action of the turbo ventilator is driven by the wind, creating a pressure difference that draws out stale air and allows fresh air to enter. This can help regulate temperature, reduce humidity, and enhance comfort within the building.
