JLF Series Non-power Wind Drive Roof Exhaust Fan

The roof ventilation fan applies the theory of convection between natural wind and air to accelerate and transform parallel aieflow into vertical so as to inprove the indoor ventilation. The hot air rises an cold air falls, which makes the fan rotate. It can effectivelly remove indoor soot, smoke, odor, moisture, heat, decorative harmful gas, dust, human metabolism and other dirty volatile mixed-doped odor as well as prevent virus and bacteria invasion and indoor pollution, improving the working environment of industriall plant.

Specifications 

1.Material: made of high- class stainless steel or color steel by stretching forming, attractive appearance, noo rust, rainproof and high efficiency ventilation.  2. Bearing: whole 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.    

Advantages 

1. Automatically operate. Take advantage of energy from nature, exhausting turbid, humid hot air to exterior and supplying fresh air to interior. Produce air convection as a heat radiator, reducing indoor temperature, increasing air fresh. Reduce air conditioning load, increasing the cooling effect.

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

3. No maintainance needed, life-long service

4. Light weight, strong and durable construction

5. Weather resistance, strong fray resistance, fine non-viscidity, 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.
