The rapid development of the industrial economy is accompanied by the construction of many light steel structure workshops. The streamlined natural ventilator has almost become the ideal natural ventilation equipment for the newly built workshops, and has played an important role in the overall ventilation and lighting of the workshops.

The streamlined natural ventilator of the steel structure industrial factory building, as a layout method of the factory air building, has been applied in many different types of factory ventilation projects.

(1) The appearance of the roof ridge vent is streamlined (arc-shaped), which is also called the arc-shaped ridge ventilator. Under normal circumstances, the streamlined natural ventilator with a throat greater than 1.5m uses profile welding; the steel roof ridge vent with a smaller throat is integrally pressed with hot-dip galvanized steel, without the need for a welding base, and can be directly installed on the roof purlin.

(2) The streamlined natural ventilator can be arranged on the slope or the ridge of the roof. It can be designed as daylighting type, heat preservation type, etc. according to the material selected for the rainproof board. Commonly used rainproof board materials are: color steel plate, insulation board, daylighting board Etc.; optional opening and closing valve plate is designed to improve the health of the opening and closing workers and improve work efficiency. Open-close type air floor (openable) or open air floor are designed as manual air floor, electric air floor, and fire-fighting linkage air floor according to the different control methods of the valve plate.
