  • 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.
