Roof turbines ventilation, roof wind turbines raindrop ventilating stainless steel roof ventilation ventilated ventilation ventilation ventilated fansHigh wind speed, strong pressure pressure, not easy to damage, compact blade structure, long life of stainless steel bladesMaterial: 304 stainless steelAdvantages: discharge indoor hot air and dirty air, purify the indoor environmentPrinciples: Utilize natural wind and indoor temperature difference, air -to -flow drives turbines rotation. Eliminates the old air in the room with centrifugal force and negative pressure.Application: For the ventilation of exterior walls such as bathrooms, kitchens, warehouses, residences, apartments, etc.packing list:1* No dynamic ventilated portSize - The package includes:110mm (4.3 inches) ventilation cap×1, clamp×1160mm (6.3 inches) ventilation cap×1, clamp×1200mm (7.9 inches) ventilation cap×1, clamp×1250mm (9.8 inches) ventilation cap×1, clamp×1300mm (11.8 inches) ventilation cap×1, fixed foot×3350mm (13.8 inches) ventilation cap×1, fixed foot×4400mm (15.7 inches) ventilation cap×1, fixed foot×4

• [Ventilation port material] The roof ventilator is made of high -quality 304 stainless steel. It is solid and durable, integrated, without deformation, smooth surface, no sharp angle.
• [Galvanized roller] The intensity is enough to withstand the wind speed of 200 km/h, and 100 kg of load without deformation or damage.
• [Talling] Arc -shaped wind leaves can ensure that the rainwater never invades. High winding efficiency, light operation, prevents rainwater from invading.
• [Application scenario] It is suitable for chimneys, farms, factory roofs, ventilation pipelines, houses, warehouses, etc.
• [Applicable to] ideal choice for residential or light commercial use. Stainless steel turbines is suitable for any roof.
