Electric smoke vents are divided into three categories: linear natural vent, triangular electric smoke ventilator, and arched continuous rooflight. 

1. Arched continuous rooflight is divided into three types: C3CT and MC3CT side opening and C3ST top opening. C3CT side-opening circular arched smoke ventilation is suitable for buildings with frequent ventilation and lighting requirements. MC3CT side-opening type is especially suitable for buildings with high ventilation requirements; C3ST top-opening arc-shaped electric natural vent is suitable for buildings that are mainly daylighted and opened only when it is necessary. The natural ventilation system has a parabolic curve and bulges from the inside to the outside, which can save space.

2. Iinear natural vent is mainly for lighting and supplemented by ventilation. When it is fully opened, the angle is 90 degrees, the maximum amount of smoke is exhausted, the skylight is parallel to the roof, and the wind resistance coefficient is small. The smoke vents can be made of lighting panels, glass, pc lighting panels and other materials.

3. Triangular electric smoke ventilator has two types: C1ST upward opening and C1XT downward opening. The upward opening type has greater ventilation, and the downward opening type has better rainproof performance.

4. Electric ventilation and smoke exhaust ventilator has the following characteristics:

4.1. The smoke vents have various models, which can be widely used in different factories and have high use value;
4.2. The smoke ventilator adopts new technologies and new materials, and the product quality is high, and its service life is consistent with the service life of the factory.
