Sdf Tunnel Axial Flow Counter-Rotating Frequency Conversion Ventilation Fan

The tunnel counter-cyclone fan is mainly used for tunnel ventilation. After entering the tunnel 150 meters, the gas and oxygen in the tunnel are insufficient, the construction environment begins to be bad, and the health of the construction personnel cannot be guaranteed. Fresh air is delivered to the tunnel through this fan. This type of fan is mainly It adopts two-section motors and two-section impellers counter-rotating, which increases the pressure and has a long transmission distance. The tunnel is divided into high-speed tunnels, culverts, water tunnels, and railway tracks, and different types of power fans are used according to the situation.

SDF press-in counter-rotating axial flow tunnel fan is a new product developed by our company on the basis of summarizing the structure and technical performance of the existing domestic press-in tunnel fan. This product has the characteristics of reasonable structure, complete specifications, high efficiency, low noise, long air supply distance, etc., which greatly reduces the labor intensity of workers and saves ventilation time. It is an ideal equipment for tunnel ventilation. It can also be used in ventilation systems such as metallurgy, chemical industry and mining.
