Plant natural ventilator is divided into roof louver vent and streamlined natural vent if we distinguish from their appearance characteristics. Among them, roof louver vent is mainly divided into low-profile ventilator and labyrinth industrial ventilator.

1. Labyrinth industrial ventilator

This type of natural ventilator is divided into two installation methods, horizontal and vertical. The appearance of this labyrinth industrial ventilator is similar with roof louver vent, but the internal structure is quite different, and its internal structure is shaped like a butterfly. The weight is light and the height is low. It has better wind resistance and it is more economical and more cost-effective.

2. Roof louver vent

According to the layout, the louvered roof vent can also be divided into two types: horizontal and vertical. The unique structure of the natural ventilator significantly increases the effective ventilation area and lighting area, smooth exhaust, and improves ventilation efficiency; the natural vent is also equipped with three-layer rain-proof panels, which greatly enhances the rain-proof performance. Light weight and low height and good wind resistance. Low-profile ventilator is widely used in coastal areas with multiple typhoons due to it's light weight and low load. Roof vents are also commonly used in buildings with high requirements for rain protection.
