The 10a low-profile ventilator is widely used in industrial plants. Because of its low overall height, it has good wind resistance. It is mostly used in areas with large typhoons such as coastal areas. Its ventilation and rain protection are superior to other low profile roof ventilators.

1. Ventilation performance

The traditional low-profile ventilator changes direction after the airflow is blocked upward, and the resistance coefficient is large. The upward airflow is easy to gather at the tip, forming a ventilation dead angle, which is not conducive to the airflow flow; Channel type natural ventilator. The exhaust is smooth and the ventilation resistance coefficient is small, about 4, which is only 1/4 of the general thin ventilator, so the ventilation performance is significantly better than the latter.

2. Rainproof performance

The natural ventilator is equipped with three layers of flashing boards. The rainwater directly hits the first layer of the flashing board, and the resulting splashes and raindrops fall on the second layer of the flashing board. The rain hits the second layer of the flashboard, and the resulting splash and rain fall on the third layer of the flashboard. The first layer and the second layer of flashing boards provided by this type of ventilator can effectively block and guide the falling raindrops. The bottom layer of the flashing board has its own drainage groove, and the flashing board and the drainage groove are integrally formed.
