Нет, Люк электрический турбины вентилятора

No-power Roof Turbine Ventilator is to make use of the air free convection that natural wind power and the interior outside temperature difference bring about, the effect driving a turbine to rotate making use of centrifugal force and negative pressure thereby discharge the interior stale hot-air It makes the fresh air flow in, thus the purpose of cleaning air can be reached Raw materials: Ventilations are made of the stainless steel Advanced totally enclosed bearingsOperating theory: Arc blades can gain the optimal exhaust effect which are calculated scientificly, ensuring the rainwater can't enter during the work The central axis is with fine steps,and the blades can never be deformed in high-speed operation, thus greatly enhancing the service life The design of variable angle neck tube can make the ventilation installed in the slope of 0 to 22.5 angle, and the installation is very simple, generally only need 30 minutes Turbine Blades can normally operate for 15 yearsFeatures: High efficient venting function Unique variable angle tube neck Special diversion vane of beveled fanner Easy to install Excellent energy-saving effectApplications: power plants, chemical plants, pharmaceutical factories, food processing plants, metallurgy, rubber, warehouses, and advanced civil buildings
