Roof Turbine Ventilator Exhaust Fan

 Non power roof fan

1.Automatic driving by wind, working 24 hours of a day

2.High sensitivity, the blades drive with slight wind, the difference in temperature also makes the blade driving.

3.Stable rotary, mute sounds so no influence of the workshop

4.Complete senior axis bearing, no lubrication

5.Corrosion resistant, acid proof and alkali proof, long time using 

6.Diameter 500mm,600mm Material : stainless steel or colored sheet

Advantages

1. Environmentally friendlly:Aonuodi rrof ventilating fan is efficient ,explosion-proof,uses no electric energy,and causes no noise and spark.
2. Dust-proof:the wind turbine exhaust fan continuously operates 24 hours a day,This lowers the possibility of dust adhesion and makes the fan easy to clean.
3. Light weight:The weight of roof ventilating fan along with the base is approximately 15 kg,so the users need not take into consideration when desiging steel structures.
4. Daylight:The interspace between blades allows natural light to provide effective internal lighting during the day,thus reducing the electricity cost by 5-10%.
5. Long lasting:Aonuodi roof ventilating fan has a life time of over 15 years.Features
6. Curved blades are the result of scientific computing technology.They are not only rainproof but also contribute to high efficiency ventilation.The blade will perform self ratation operations quietly in circumstances where teh breeze is not less than 0.2m/s and teh indoor and outdoor termperature difference exceeds 0.5 .
7. In addition to flat roof,Aonuodi roof ventilating fan can also be used on pitched roof ( )
8. The special central shaft design effectively prevents turbine blades rotating at high speeds from deformation,thus greatly extending the service life of the roof ventilating fan without power.
9. The U.S.PEER.UBC,and Japan NSK high-precision bearing system(fully closed)with guaranteed quality.Solid spherical structure and permanently lubricated upper and lower ball bearings combine the need for maintenance and parts replacement.
10. Aonuodi roof ventilating fan without power can be easilly installed on the concrete roof and contour plate of various industrial plants without any bracket.
11. As the roof ventilating fan requires no electricity cost and low installation cost,it can greatly save on users total cost.
