Our 600mm Wind-Driven Cyclone Ventilators are engineered for high-efficiency, passive air extraction in industrial and commercial buildings. Made from aerodynamically designed aluminum alloy or stainless steel, these ventilators operate without electricity, harnessing wind energy to create continuous airflow. With a throat diameter of 600mm, they deliver powerful ventilation up to 2750 CFM, effectively expelling heat, fumes, and humidity. Features include double ball bearing rotation, corrosion resistance, noise-free operation, and minimal maintenance. Ideal for factories, warehouses, workshops, and metal roofing systems.
