The face type blows out the wind, the air volume is large, and there is no blowing feeling. The South system adopts the unique surface air outlet mode of the fiber infiltration of the entire pipe wall and the microporous jet flow. The air outlet area is large, the air volume is large, the wind speed is low, there is no blowing feeling, and the comfort is excellent. The overall air supply is evenly distributed. The South system blows out air through the fiber gaps in the entire pipe wall or evenly distributed rows of small holes designed to achieve a truly ideal overall uniform air distribution. Anti-condensation. The South system penetrates the cold air through the fiber of the whole pipe wall, forming a cold air layer outside the pipe wall, so that there is almost no temperature difference between the inside and outside of the pipe wall, completely solving the problem of condensation, without pipe insulation, easy to clean and maintain, and healthy and environmentally friendly. As the Soth system is easy to disassemble and assemble, the pipes can be wiped and cleaned conveniently, so as to improve the clean quality of indoor air and meet higher requirements for health and environmental protection. Beautiful and high-grade, diverse colors, outstanding individuality. A variety of colors can be in harmony with any indoor environment style, simple and high-end. At the same time, the system and color are completely personalized and customized. Light weight, negligible roof load. The South system is woven from special fibers and is extremely light, about 1/40 of the traditional metal wind system. It is especially suitable for places where the roof has no load-bearing capacity. The installation is simple and the engineering cycle is shortened. The South system adopts a special supporting steel rope or aluminum rail suspension device system, which is simple and quick, and the installation time is often more than 1/10 of the traditional system, which greatly shortens the engineering cycle, is flexible in installation, and can be reused. The whole system is made of soft materials, so there is no need for trim calibration during installation.
