The SWF series mixed-flow fans have been included in the national Spark Program. Compared with centrifugal fans of the same model number, they deliver larger air volume; versus axial fans, they generate higher wind pressure, and they support axial mounting as a key advantage.This fan series has been adopted for numerous landmark buildings, including the Auditorium of Zhongnanhai in Beijing, Zhongguancun in Beijing,Shanghai No.1 Department Store, Shanghai Pudong International Airport, Nanjing White Palace Hotel, Shenzhen Guoxin Mansion, Jiangsu Zhongshan Mansion, Dalian Olympic Square, and Hyatt Regency Hangzhou. Bulk shipments of the fans have also been exported to Singapore and other Southeast Asian countries and regions.End users speak highly of the product, citing its low noise, low power consumption, wide high-efficiency operating range, easier installation and operation than centrifugal fans, and reliable performance.
