Ventilation. Wind-DrivOur Roof turbine ventilators are made of stainless steel, and import the UBC bearing from USA. All the parts of the turbine ventilators are finished by the professional molding tools, they are assembled after checking by the professional equipments. It works without the electricity power, they can change our air condition indoors, leave us a comfortable environment. Also, when used in a workshop or a storeroom, they can advance the working environment, and this improves the workers' efficiency.Experienced StaffGreen ProductCompetive PriceQuality ApprovalsReputation and ServiceNo-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-airIt makes the fresh air flow in, thus the purpose of cleaning air can be reachedRaw materials:Ventilations are made of the stainless steelAdvanced totally enclosed bearingsOperating theory:Arc blades can gain the optimal exhaust effect which are calculated scientificly, ensuring the rainwater can't enter during the workThe central axis is with fine steps, and the blades can never be deformed in high-speed operation, thus greatly enhancing the service lifeThe 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 minutesTurbine Blades can normally operate for 15 yearsFeatures:High efficient venting functionUnique variable angle tube neckSpecial diversion vane of beveled fannerEasy to installExcellent energy-saving effectApplications: Power plants, chemical plants, pharmaceutical factories, food processing plants, metallurgy, rubber, warehouses, and advanced civil buildingsOur ventilator factory is the professional suppliers for solutions to skylight, ventilation and firefighting smoke ventilation for different kinds of construction buildings.
