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 bearings 
Operating 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 years 
Features: 
High efficient venting function 
Unique variable angle tube neck 
Special diversion vane of beveled fanner 
Easy to install 
Excellent energy-saving effect 
Applications: power plants, chemical plants, pharmaceutical factories, food processing plants, metallurgy, rubber, warehouses, and advanced civil buildings
