Natural Air Ventilators Suppliers and Manufacturers

Hao ventilator is a product designed for the purpose of better ventilation of hot /polluted air and to make the premises free from any type of suffocation or humidity. It increases the air flow and decreases the temperature of the premises without the use of electricity or any kind of fuel and this is the reason we also call it “natural exhaust system”. Working principle of natural ventilation system Hao ventilators utilities wind energy to rotate its vanes and as the vanes moves it starts pushing out the air filled in between the vanes because of centrifugal force, and out-side flow of air creates a low pressure zone in the inner area of ventilator. This low pressure zone will suck air from inside the shed and fresh air comes in the shed through windows or doors to take place of air which has been sucked by the ventilator. This continuous cycle of air flow leads to natural air ventilation. 4"ss/pp, 8"ss, 16" ss/pp, 20 "ss/pp, 22" pp/ss 430grade/ss 304 grade, 24" ss

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. 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 nosie. 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.
