The roof ventilation fan applies the theory of convection between natural wind and air to accelerate and transform any parallel airflow into vertical so as to improve the indoor ventilation. The hot air rises and cold air falls, which makes the fan rotate. So the indoor heat, stink and dust are exhausted effectively. It also can effectively remove indoor soot, smoke, odor, moisture, heat, decorative harmful gas, dust, human matabolism and other dirty volatile mixed-doped odor as well as virused and bacteria invasion. As a result, it improves the working environment, protects workers' health and enhances the working efficiency.
It is widely used in warehouse, toilet, factory, workshop, stadium, tennis hall, assembly hall, garage, paper mill, galvanization factory and coating factory.
