Linear natural vent mainly focuses on daylighting. The smoke vent rooflight is widely used in auto parts factory, mechanical processing plants, light industrial building plants, etc. 

The frame material of the linear smoke ventilation is usually made of aluminum alloy profile, its tensile strength is 160N/mm2, the yield strength is 110N/mm2, the hardness is HV≥58., the wall thickness is 1.4, the lighting material can choose laminated glass, safety glass, polycarbonate daylighting board, glass fiber polyester daylighting board, etc., users must indicate the daylighting materials when purchasing customized smoke vents.

The top of the window of the linear natural vent should be parallel to the installation surface, so that the wind resistance coefficient can be greatly reduced, and the wind resistance performance can be further strengthened. The large opening angle of the straight-shaped automatic opening vent is 90°. When the electric smoke vent rooflight is fully opened, a large amount of ventilation, smoke and air exchange can be achieved, providing an excellent working environment inside the plant.
