Technical Field

[0001] This utility model relates to the field of tunnel ventilation technology, and in particular to a tunnel ventilation fan. Background Technology

[0002] Tunnel ventilation fans, also known as tunnel jet fans, are widely used in water conservancy dam projects, highway, railway, and subway tunnels.
