Triangular smoke vent is used for automobile and logistics industrial plants. Triangular smoke ventilation includes daylighting window sash, aluminum alloy window frame, electric window opener and control box. The window sash and the installation roof form an angle of 30°. The inclined sash surface structure design is designed for rainwater and snow flows into the drainage ditch along the smoke vent windows and will not accumulate on the roof and smoke ventilators, reducing its bearing pressure to a certain extent, and protecting the smoke vent. Triangular roof smoke vent has three methods: ordinary control, intelligent control and intelligent network control. It is mainly used in steel structure workshops and industrial workshops with lighting as the mainstay and ventilation and smoke extraction as the auxiliary. The window sash lighting material can choose FRP lighting board or polycarbonate lighting board (sun board), these two types of lighting materials have obvious advantages in light transmittance and lighting rate, and guarantee The plant has enough daylight. In the case of ventilation and smoke exhaust, it can be realized by opening the electric sunroof.
