Product Specifications: 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:

Ventilation are made of the stainless steel
Advanced totally enclosed bearings

Operating theory:
Arc blades can gain the optimal exhaust effect which are calculated scientifically, 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
