1. The Theory of Its Running
Our Turbine Roof Ventilations need no the electric power instead of easily drive the turbine vanes rotating by nature breeze or the temperature difference between indoor and outdoor so as to make true the running without cost.
2. The Constitutes of the Material
Our No power turbine roof Ventilations are made of the stainless steel which need no maintenance and are of anti-acid-base and of anti-erosion by the only once investment.
We use the UBC bearings from USA
3. Our TG Turbine Roof Ventilators are possessed with the following traits: no power exhausting, saving energy and money; anti- acid - base, anti- erosion, long-lived used; no noise, no pollution, absolutely environmental protection; improving the air quality, raising working efficiency; conveniently setting up and so on.

We produce many kinds of terbine ventilators,suh as TG-880,TG-500,TG-300.TG-880 are specially used in the big industrial workshops,storerooms,and the big buildings which have much harmful air and the temperature is very high;TG-500 are used in the general industries and the small buildings;TG-300 are used in the advanced houses and the ventilating pipes.
Features:1) Do not need electric force
2) Protection against high temperature,bad air environment
3) Anti-corrosion,anti-acids and bases,anti-oxidation
4) Long usag
