The roof ventilation fan applies the theory of convectionbetween natural wind and air to accelerate and transform anyparallel airflow into vertical so as to improve the indoorventilation. The hot air rises and cold air falls, which makes thefan rotate. So the indoor heat, stink and dust are exhaustedeffectively. It also can effectively remove indoor soot, smoke,odor, moisture, heat, decorative harmful gas, dust, humanmatabolism and other dirty volatile mixed-doped odor as well asvirused and bacteria invasion. As a result, it improves the workingenvironment, protects workers' health and enhances the workingefficiency.
It is widely used in warehouse, toilet, factory, workshop, stadium,tennis hall, assembly hall, garage, paper mill, galvanizationfactory and coating factory.
Advantages:
1)High-efficiency ventilation
2)High-quality stainless steel body
3)Easy and fast installation.
4)Environmental protection, energy saving and noelectricity cost.
5)stable and durable, dehumidification, anti-sweatand rain-proof.
6)High sensitivity and no nosie.
7)All the ventilators adopt American UBC bearings,free lubrication. Supporting brackets are all made of stainlesssteel, which has very good corrosion-resistant ability.
