Zefeng was founded in 2011 in Shenzhen, Guangdong, and its early employees had many indissoluble ties with Yuanda, and now has its own large-scale production base in Dongguan.
 
Zefeng's product line is mainly cabinet-type fresh fans, and a small number of wall-mounted fresh fans have also been launched to fill the gap in the product line. Xiangrui 380, 380A, 400A, 787A and 919C are the main models of Zefeng, and the numbers in the models represent its maximum fresh air volume, up to 919m³/h, which is very suitable for large families, and can also be used in office areas, conference rooms, classrooms and other indoor scenes with large spaces. Among them, Xiangrui 380 is the key promotion product of Zefeng, mainly in the appearance of improvement, the dark brown metal shell is more calm and atmospheric, and the overall texture of the product has been improved.
 
The filtration system of the Ze air cabinet fresh fan is a conventional three-layer filter screen, the overall performance is decent, and it also has a sensible heat exchange function, although it can not exchange humidity at the same time as full heat exchange, but the sensible heat exchange has greatly expanded the use range of products, but Zefeng has not announced the heat exchange efficiency. In addition, Zefeng's fresh air fans also support internal circulation mode, when outdoor pollution is extremely serious, the fresh air system can be transformed into an air purifier, without introducing outdoor air, thereby prolonging the service life of the filter.
 
Although Zefeng has opened an official flagship store on the Internet, because the new fan involves offline communication, door-to-door installation, etc., Zefeng has always emphasized that the market focus will be offline, and the official flagship store is more likely to increase brand exposure and popularity, or facilitate users to buy replacement filters.
