Natural roof ventilation is installed on the roof of the factory building. As important ventilation and smoke exhaust equipment, smoke ventilation is widely used in electronics, furniture, automobiles, ships, manufacturing and other industries. As a professional smoke vents manufacturer, Mcwell will focus on the application of roof smoke vent in industrial plants.

1. Explanation of the ventilation principle of the natural roof ventilation

The ventilation principle is to use the thermal pressure difference caused by the temperature difference and the effect of the wind to discharge the exhaust gas dust smell, inhale fresh air, reduce the temperature inside the workshop, and then realize the ventilation and smoke exhaust of the workshop, so create a good working environment for workers.

2. The composition of the smoke vent rooflight on the roof of the factory

The main components of the natural ventilator include the skeleton (main skeleton, secondary skeleton), outer guard plate, waterproof tank, opening and closing valve plate, deflector, flashing plate, electric control box, etc. According to the installation layout, it can be divided into ridge ventilator and slope natural vent. 

3. The size design of the ridge vents' throat 

The throat size of the ridge ventilator is determined according to the amount of smoke exhaust, the factory roof. Generally speaking, different types of natural vent has different throat sizes. The streamlined ridge ventilator has larger throat sizes. The design range is 1500-9000mm, and the throat size of the small throat streamlined ventilation skylight is 600-1500mm.
