Roof Ventilating Fan without Power

Roof Ventilating Fan without Power

Advantages
1. Environmentally friendly: Aonuodiroof 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 aday. This lowers the possibility of dust adhesion and makes the fan easy toclean.
3.Lightweight: The weight of roof ventilating fan along with the base isapproximately 15Kg, so theusers needn’t take it into consideration when designing steel structures.
4. Daylighting: The interspacebetween blades allows natural light to provide effective internal lightingduring the day, thus reducing theelectricity cost by 5-10%.
5. Long lasting: Aonuodi roof ventilating fan has alifetime of over 15 years.

Features
1. Curved blades are the result of scientific computing technology.They are not only rainproof but also contribute to high efficiency ventilation.The blades will perform self rotation operations quietly in circumstances wherethe breeze is not lessthan 0.2 m/s and the indoor and outdoor temperature difference exceeds 0.5 ℃.
2. In addition to flat roof, Aonuodi roof ventilating fan can also be used on pitchedroof(≤31.5°). 
3. The special central shaft design effectively prevents turbine bladesrotating at high speeds from deformation, thus greatly extending the servicelife of the roof ventilating fan without power.
4. TheU.S.PEER, UBC, and Japan NSK high-precision bearing system (fullyclosed) with guaranteed quality. Solid sphericalstructure and permanentlylubricated upper and lower ball bearings combine to eliminate the need for maintenance and parts replacement.
5. Aonuodi roof ventilating fan without power can beeasily installed on the concrete roof and contour plate roof of various industrial plants without any bracket.
6. As the roof ventilating fan requires no electricity cost, no maintenancecost and low installation cost, it can greatly save on users’ total cost.

Applications
Aonuodi roof ventilating fan without power issuitable for use in factories, warehouses, villas,patio, greenhouses,livestock houses, mining tunnels, and more. Typically, it is usedin the following applications.
① It removes heat through the process of radiation, convection
② It reduces the indoor temperature and improves the indoor air quality.
③ The roof ventilating fancan work together with air conditioning to create better refrigeration effect.
④ It can keep the roof dry by removing moisture, steam, etc.

Principles
Aonuodi roof ventilating fan without power uses natural wind force and thermalconvection caused by indoor and outdoor temperature difference to drive theturbine to rotate, and thereby draw out stable and impure hot air indoors viacentrifugal force and negative pressure.

Technical Parameters of Roof Ventilating Fanwithout Power

Note: 1. The air volumeobtained here is according to circumstances where the average wind speed is 3.4m/s and the indoor and outdoortemperature difference is 5℃. If the wind speed increases, the airvolume will increase accordingly. If the indoor and outdoor temperature differenceexceeds 5℃, you canincrease the number of fans.
         2. If the building is less than 6m, please use 14" or 20".Otherwise, please choose 25", 27" or 30"
