Electric smoke vent rooflight can be divided into triangular smoke exhaust ventilator, linear natural vent and arched shape continuous rooflight according to their appearance characteristics. It is mainly used for industrial plant's roofs that are mainly daylighted and opened. In order to take advantage of the multiple advantages of electric smoke exhaust skylights, combined skylights can be used.

1. Common combined electric smoke vent rooflight are C1ST triangular smoke exhaust ventilator and arched shape continuous rooflight. The combination of the two window types simultaneously meets the multiple requirements of roof ventilation, smoke exhaust, and lighting;

2. The length and position of the triangular smoke exhaust ventilator unit can be adjusted according to the design. When the window sash is opened in a non-continuous arrangement, the direct push method of the window pusher is usually selected for opening;

3. The combined fire-fighting automatic opening vents method combines the triangular and arched skylight methods and process requirements. In addition, an integral buckling water tank at the end of the horizontal drainage groove at the junction of the skylight is added to form structural waterproofing.

The combined roof smoke vent can give full play to the ventilation and smoke exhaust advantages of the triangular electric lighting and smoke exhaust skylights, and can also take into account the efficient lighting function of the dome-shaped fixed skylights. It is a very practical and functional electric smoke exhaust skylight. It plays an important role in various industries such as electric power, logistics, and machinery manufacturing.
