Product name: "roof turbo ventilator"/" roof top turbine ventilator" "Wind driven roof turbine Ventilator" / "Mini turbine ventilator" 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 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. 1. The product's material: stainless steel, Aluminum, and color coated steel, usually used three types. Stainless steel is the most popular. 1). Stainless steel: (SS201/SS304), Usually choose SS201, its quality is good, its price is the best, it is used to roof house, workshop, and so on. if be used in chemical industry workshop and coastal regions, s estion choice SS304, or painted stainless steel. its corrosion resistance is the best." 2). Aluminum: material is softer, it is not best, if our customer choose this material, we will accoring to our customer's requests to produce. 3). Color coated steel sheet: its price is the cheapest, it is suitable for the inland common houses and workshop. 2. The product's type(size): according neck diameter or the throat diameter. 80mm----1200mm. Usually size and used: Mini type:200mm/300mm/400mm; usually be used Roof chimney and Ventilation tube, the size we can according customer' requests to produce. Middle type:500mm/600mm/700mm/800mm, it is used to roof house, workshop, and warehouse, and so on. Be widely used. Larger type: 900mm/1000mm/1100mm/1200mm. It is used to larger workshop and warehouse. 3. Benefits of Roof Turbine Ventilation Systems: 1). Old air is extracted removing heat, fumes, steam and dust 2). Improves people' s productivity 3). Improves indoor air quality 4). Water and bird proof 5). Reduces structural damage in lofts 6). Protects stored goods 7). Human and environmentally friendly 8). Requires no electricity
