One of the main functions of subway tunnel fans is to ensure fresh air inside the subway tunnel. When the subway train is running, it brings air and dust into the subway tunnel, and the tunnel fan can send fresh air into the tunnel, expel polluted air from the tunnel, and maintain air circulation, making the air inside and outside the station and train fresh.

    In subway tunnels, due to the operation of trains, a large amount of heat from electrical equipment is often generated. If tunnel fans are not used to remove heat and smoke, it may cause fires. Tunnel fans can remove heat and smoke, effectively preventing fire accidents in subway tunnels.

    The subway tunnel fan also plays a role in maintaining the safe and stable operation of the subway. It can not only keep the air fresh and prevent fires, but also stabilize the temperature of the subway tunnel environment, maintain normal oxygen concentration, control humidity, etc., providing passengers and staff with a stable and safe riding environment.
