The streamlined natural ventilator has beautiful appearance, which can play a good role in ventilation and decoration for industrial plant. The roof smoke vent is mainly used in large-scale steel-structure industrial plants, such as large power plants and some economical places with high spaces that require natural ventilation. The ridge ventilator can promote the heat exchange inside and outside the industrial plant, which can effectively discharge the hot air in the plant, and introduce outdoor cold air to fill it, forming air convection and reducing the temperature in the plant.

At the same time, the steel roof ridge vent can discharge moisture, dirty gas, water vapor, dust or harmful gases in the factory building to the outside, promote air circulation and convection in the factory building, and supplement enough outdoor fresh air to improve the working environment and ensure employees' health. A good ventilation environment also makes human body fluids evaporate, which has a natural cooling effect, thereby avoiding discomfort caused by poor heat removal by employees, and improving work quality and efficiency. Therefore, roof smoke vent play an important role in large-scale industrial plants and plants in a polluted environment.

On the other hand, since the smoke vent rooflight perform ventilation activities on the roof, one is to provide protection from wind, rain, and snow. Therefore, there is a rainproof board inside the ventilating skylight to protect against rain and snow, and an outer guard board is used to protect against wind. The working steps of the arc-shaped roof skylight are very simple. As long as the power switch is turned on, the motor inside the ventilation skylight will start to rotate, and drive the wire rope on the motor, and open the valve plate to allow ventilation.
