A commercial center in Guangdong has a constant flow of customers throughout the year, and the building structure is complex and intricate, especially in some areas where semi open spaces require corresponding and applicable solutions. After unified planning by our company, a batch of Rundongfang Industrial fans were installed. The technology of industrial ceiling fans originated in the United States and is particularly suitable for large building spaces. Through the slow rotation of six giant propeller blades, it can effectively drive large-scale air circulation, allowing customers to have a good spatial environment experience indoors, semi open corridors, and activity areas. It provides a feeling of oxygen deficiency in general commercial environments.
