Roof ventilation fan -Specifications / structure

2.  Bearing: wholel sealing bearing, which can ensure it operates smoothly and constantly.

3.  Special central shaft design, high-class lubricating bearing system: preventing turbine blades

rotating at high speed from deformation, and extending the service life.   

4, Inside support frame: cast iron. 

Roof ventilation fan -Advantages 

1, Automatically running. wind drive. One time investment, no anymore cost.

2. No operating cost, no electricity consumption, environmental protection, energy-saving.

3. No need maintenance, long life working.

4. Light weight, strong and durable construction.

5. Weather resistance,  self-cleanness, high revolving sensitivity and high air venting efficiency.   

6. Easy installation:installation position: flat roof, pitched roof, concrete roof and contour plate of various industrial plants.

7, waterproof efficiency may reach 100%. 

Roof ventilation fan -Function:

1)      Exhausting turbid, humid hot air to exterior and supplying fresh air to interior.

2)      Produce air convection as a heat radiator, reducing indoor temperature, increasing air fresh.

3)      Reduce air conditioning load, increasing the cooling effect.

Roof ventilation fan Widely used in these places

1) Ware house;

2) Factories and workshops (such as paper mill, galvanized products producing factories,

painting factories);

4) Garage and other buildings which need air ventilate.

Advantages:

1)High-efficiency ventilation

2)High-quality stainless steel body

 3)Easy and fast installation.

4)Environmental protection, energy saving and no electricity cost.

5)Stable and durable, dehumidification, anti-sweat and rain-proof.

6)High sensitivity and no noise.

 7)All the ventilators adopt American UBC bearings, free lubrication. Supporting brackets are all made of stainless steel, which has very good corrosion-resistant ability.
