Tunnel fans are specially designed ventilation systems used in tunnels, underground mines, and subterranean construction projects. Their primary function is to deliver continuous fresh air and exhaust dust, fumes, and harmful gases, ensuring a safe and breathable environment for workers.
These fans are known for their large airflow capacity, high pressure output, stable performance, and reliable operation. Depending on the application scenario, tunnel fans can be configured as axial, centrifugal, local ventilation, or explosion-proof models.
They are widely used in highway and railway tunnel construction, subway projects, metal and coal mining, underground utility corridors, and urban smoke exhaust systems.
To meet complex site requirements, tunnel fans can be equipped with accessories such as silencers, flexible ducts, VFD control, and flameproof motors—enhancing overall safety and automation of the ventilation system.
