6" 8" 10" 12" Rotating Roofing Wind Turbine Stainless Steel Non Power Roof Ventilator, 110-400mm Turbine Roof Vent for Houses Factory Attic Farm Leak Proof Vent Cap Fan(400mm/15.7in)

This is a non-powered exhaust system with a spherical blade design. It is widely used for ventilation in large factories, warehouses, stadiums, animal farms, high-rise buildings, and residential buildings. It utilizes the temperature difference between indoor and outdoor air to generate convection, driving the turbine to rotate. Centrifugal force then creates negative pressure to expel polluted air from the room. It is easy to install and requires no external power source.SpecificationsColor: SilverMaterial: 304 stainless steelDimensions: 4.3in-5.7in（110mm-400mm）Function: Exhausts hot and polluted air, purifying the indoor environment.Package Included: Non Power Roof Ventilator × 1 + accessoriesNote:Ensure proper installation to prevent leaks and ensure efficient operation. Also, regularly inspect the vents for any debris or obstructions that could affect airflow.
