Advantages of Ampelair natural ventilation type 880    
             
                                         
Ampelair natural ventilation  type 880 with high durability ismainly composed of  a  turbo head, a waterproof substrate and a middle body (circle or square appearance).

1、 Well corrosion resistance, enjoying 10 years quality assurance 

 High-quality stainless steel body can bear a long period of bad weather and resist  against indoor corrosive gases .Low friction force sealed bearings and durable lubrication make it needs no maintenance at all.

2、 Shaft and bearings 

Ampelair ventilators adopt the United States  UBC  sealed bearings . There is  strong corrosion resistance with C45 steel as a  main spindle. 

3、Vanes

Wave-type vanes are designed precisely in accordance with the principle of fluid mechanics  .Even though the breeze can also make it rotate freely, it's performance of resisting against snow and rain is terrific . Because of the wave shape, mechanical strength is greatly increased compared with those of similar products.
