With the continuous development of industrialized production and the continuous expansion of industrial buildings, the emission of industrial harmful substances is increasing. If scientific and effective control and treatment are not carried out, it will seriously pollute the indoor and outdoor air environment. Natural ventilator on the plant's roofs is important equipment to build new plants to improve the working environment and labor environment.

Ridge ventilator uses the temperature difference effect to exhaust the dirty indoor air to the outdoors, and the fresh outdoor air is replenished indoors by flowing, so as to keep the indoor air environment in line with standards and meet the needs of the production process.

The main tasks of natural roof ventilation are: to add fresh air to the room to meet people's demand for oxygen; to dilute and circulate the air in the building to reduce the concentration of harmful gases; to control industrial harmful substances, to control dust and harmful in the production workshop gas or steam, residual humidity, residual heat.

General civil buildings and some small industrial plants with low heat generation and slight pollution usually only require keeping the indoor air clean and fresh, and improving the indoor air parameters (temperature, humidity, cleanliness, flow rate) to a certain extent, Only general ventilation is required, and no special treatment is required for intake and exhaust. It can be used to ventilate through doors and windows, reduce the temperature of the hall, and increase the airflow speed by electric fans.

Many industrial production workshops emit a large amount of heat, humidity, industrial dust, harmful gases and steam during the production process. Therefore, protective measures are taken to create good working conditions, eliminate the health hazards to workers, and ensure the normal production process. The installation of natural vent on the roof has no power consumption, uses aerodynamics to achieve the purpose of ventilation, while taking into account the lighting function, reducing enterprise power consumption, improving the working environment of workers, and improving work efficiency. It is an excellent choice for industrial enterprises to build large-scale factories.
