Under the dual pressure of saving energy and maintaining indoor good air quality, people have begun to promote the use of natural ventilation technology. The natural ventilator uses the principle of heat pressure and wind pressure to ventilate the industrial plant naturally. It has the advantages of energy saving, improvement of indoor thermal comfort and improvement of indoor air quality. It is a kind of ventilation method with great potential and improved human history. The original means to adjust the indoor environment for a long time. We have a preliminary understanding of the natural vent. So what is the throat of the natural roof ventilation? We know that if a new industrial plant needs to install a natural ventilator, the steel structure company will reserve ventilation holes on the roof when the factory construction is completed. And the throat of roof vents refers to the same size between opening hole of the roof and the ridge ventilator. Its size determines the amount of ventilation.

The standard of the throat of the smoke vents refers to the national standard atlas, and its size is in the range of 0.6 to 9 meters. The larger size of the throat means the larger volume of the smoke ventilation, and more average hourly ventilation, which is suitable for industrial plants with high ventilation requirements. For industrial plants with general ventilation requirements, natural ventilation system with smaller throat size can be used. As mentioned, why do we need to know the size of the throat? Because according to the size of the throat, it is possible to calculate material amount that natural ventilator needs to produce, and calculate the price of the smoke vent system.

The steel roof ridge vent is a customized product with a wide range of throat sizes.  Each smoke vents of the corresponding size has its own advantages when used in industrial plants. When users determine the throat size of the natural lighting and ventilation in an industrial plant, users can choose the appropriate throat size for customization according to the required ventilation requirements of your own production characteristics.
