Natural ventilator mainly use the air flow caused by the temperature difference between indoor and outdoor to achieve the purpose of ventilation.  

The principle of natural ventilator

The heat pressure and wind pressure formed by the temperature difference between indoor and outdoor are used to form wind pressure, so that the indoor hot air rises and is discharged through the ventilator outlet. The outdoor fresh cold air enters the room from the natural vent inlet to achieve natural indoor and outdoor ventilation. It is proportional to the height difference of the exhaust outlet and the effect of heat pressure. The greater the heat pressure difference, the more obvious the effect of ventilation and exhaust.

Classification of ridge ventilator

Natural ventilator is roughly divided into thin natural ventilators, streamlined natural ventilators, etc. According to it's appearance and shape; the specifications and models of industrial ridge vent is generally divided according to the size of the holes, and the ventilation performance of natural ventilator from different manufacturers are also different.
