• 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
