2. Product Overview
Long Distance Tunnel Ventilation Fan
The Long Distance Tunnel Ventilation Fan is a high-pressure axial flow ventilation fan designed for underground construction projects requiring continuous fresh air supply over extended distances.
The fan is mainly used with flexible ventilation ducts to deliver fresh air to:
Deep tunnel excavation faces
Underground construction areas
Mining development sections
Remote working zones
It effectively removes:
Dust
Blasting smoke
Diesel exhaust gases
Harmful gases
Heat accumulation
The high-pressure design allows the fan to overcome ventilation resistance caused by long-distance ducts and complex underground environments.
