Thin roof natural ventilator is a common type of roof natural ventilator, and they are also a type of ventilators with a higher frequency of use. The low-profile ventilator has a flat rectangular parallelepiped structure in appearance, and the window height is low, generally no more than 800mm. Therefore, this model has good wind resistance and light load characteristics. Common roof louver vents mainly include the following types of products:

1. mcw1 type natural ventilator

The mcw1 thin roof natural ventilator has the characteristics of good wind resistance and good rain resistance. The rainproof board adopts a unique design. There are three layers of rainproof boards. The third layer of rainproof board receives rain and fog, effectively preventing strong wind and rain. It is suitable for occasions with high requirements for rainproof performance.

2 mcw2 labyrinth industrial ventilator

The MCW2 labyrinth industrial ventilator mainly adopts a single-layer rainproof board, and is installed in a modular combination, which can be installed in multiple rows in the length direction of the opening. From the perspective of design and installation costs, this type of factory floor thin ventilator requires a lower cost.

3. TC10 thin roof ventilator for daylighting

The structure and function of the TC10A type is similar to the MCW1 type thin natural ventilator in the national standard atlas 11CJ33.
