1. Linear natural vent

The electric linear natural vent is a building roof with lighting as the mainstay and ventilation as the supplement. When the full opening angle is 90°, the smoke exhaust is large, the skylight is parallel to the roof, and the wind resistance coefficient is small. The length of the smoke vent can be determined according to the actual needs of the building. Therefore, the quotation of lineral roof vents need to be comprehensively quoted in terms the drawings and the actual material parameter standards.

2. Triangular electric smoke vent

The triangular-shaped electric smoke vent is mainly used for lighting and ventilation. The effective vent is basically same with the roof opening, so the structure of roof smoke vent determines that its ventilation can reach the ideal state. The excellent ventilation performance also reflect in its price, but the total price also will be quoted around the skylight material, quantity, logistics, labor and other aspects. 

3. Arched continuous rooflight

Arch type continuous rooflights can be divided into side opening type, sliding type and top opening type. The control mode is mainly general control mode. The arched smoke vent system can realize the firefighting linkage, which can be controlled according to the rain, smoke, wind, temperature, etc. The quotation is based on architectural drawings and procurement requirements.
