More and more factories are installing opening low-profile ventilator on the surface to realize the air circulation inside and outside the factory buildings, so as to achieve the purpose of ventilation and fire fighting and smoke exhausting for the workshops. Mcwell will introduce the design points of this type of opening smoke vents.

1. Now the country vigorously advocates the concept of "green, environmental protection, and energy saving", so this concept should also be followed when designing opening low-profile ventilator, and green and environmentally friendly raw materials should be used to avoid environmental pollution and achieve sustainable development.

2. Now users not only pay attention to the practicality of products, but also put forward higher requirements for appearance. When designing smoke vents, the brand, color and thickness of the main frame, outer guard plate, end sealing plate and other components must be consistent with the roof panel. One is beautiful, and the other is to ensure the same service life.

3. Since the open skylights for lighting and ventilation are installed on the factory floor, they have been exposed to the outside for many years, experienced wind, rain, sun exposure, and even suffered extreme weather and natural disasters such as strong winds, rainstorms, heavy snow and earthquakes. When the type is used, the structural engineer should calculate the material selection and connection points of each component through professional software to ensure that the climatic conditions and actual working conditions of the project location are met, and the safety of the plant skylight structure is guaranteed.

4. The open-type thin roof ventilation skylight is not equipped with an electric opening and closing valve plate, that is, this type of industrial plant ventilation skylight can achieve 24-hour uninterrupted ventilation for the workshop. Therefore, it has good ventilation and smoke exhaust performance.
