Subway tunnel solutions

Shangfeng Brand successfully developed the DTF type axial flow fan for subway tunnels in 1999, and in 2000 it successfully passed the national-level scientific and technological achievement appraisal, with its technology and craftsmanship reaching the then international advanced level. The company was the first in China to develop large-flow, high-pressure, high-efficiency, and low-noise ventilation and air handling equipment for subway tunnels, completely replacing imported products and changing the situation where ventilation and air handling equipment relied on imports. Subway tunnel fans, valves, and silencers have been successfully applied to over 200 major domestic and international projects, including the Beijing Subway, Shanghai Subway, Guangzhou Subway, Shenzhen Subway, Hong Kong Subway, Singapore MRT, Nanjing Yangtze River Tunnel, Taihu Tunnel, and Singapore Thomson Line.

Application Scenarios

Highway and railway tunnel ventilation and air treatment

Highway and railway tunnel ventilation and air treatment

Highway and railway tunnel ventilation and air handling systems can deliver fresh air, effectively removing dust and noise from tunnels, exhausting harmful gases and smoke from inside the tunnels, and maintaining good air quality and traffic safety.


Subway ventilation and air handling

Subway ventilation and air handling

Subway ventilation and air handling systems are crucial for ensuring the safety and comfort of passengers. Our company provides high-efficiency, reliable, safe, and durable fans, dampers, and silencers to address ventilation and air handling needs in subway tunnels and stations, safeguarding the safe operation of subway projects.
