According to the national industrial enterprise design and sanitation standards, the main function of natural ventilator should be natural ventilation and daylighting. In order to meet the requirements of natural ventilation and daylighting, at the beginning of the design of modern industrial plants, natural vent will be designed and installed. Before installing natural roof ventilation, many users would want to know the ventilation principles and whether it's ventilation effects are effective. In the production process of an industrial plant, a large amount of heat and harmful gases are generated. When the temperature difference between the inside and outside of the workshop is different, and the indoor air temperature is higher than the outdoor air temperature, because the hot air is light, it will rise upward, so the outdoor air changes enter into the room through rought vents. The above is the use of the principle of heat pressure, and the use of wind pressure.

The natural ventilation caused by wind pressure can also ventilate the room by using the power of natural wind. There are doors and windows on the building, and the wind can blow from the doors and windows on the windward side, blowing indoor hot air from the leeward side and natural ventilator to achieve the purpose of indoor ventilation.

The natural ventilator requires no power consumption, no noise, and low maintenance rate during the entire ventilation process. It is a convenient and practical ventilation and environmental protection product, and it is worthy of investment and application in the majority of industrial plants.
