The Theory of Its Running
Our Non-power Ventilations do not need the electric power, easily driving the turbine vanes to rotate. It begins to revolve at the wind speed of 0.20m/ s or when temperature difference between indoor and outdoor is as to make sure the running without cost.They are the real practical and energy saving products without noise and pollution., so they can save much electric power and labor for users in order to lower the production cost clearly, to improve the working surrounding of the workshop, to rise the working efficiency even to strengthen the quality of the their products.
The Constitutes of the Material
The Base plate,Multi-angle neck,Turbine of the ventilator adopted 201 stainless steel,Pre-painted Galvanized steel with 100g/m2,the Base plate thickness is over 0.6mm.We assure you a product with strong rust resistant capability,Corrosive resistance ,acid and alkali resistance.long service life.
The Values of the Non-power Ventilations
A. They can exhausted the hot air, waste gas, dust and other harmful gas meanwhile the fresh air outdoor can come into the workshop so as to better the working surrounding, to make the workers more energetic and to increase the benefits of the company.
