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.
