2. Product Overview
Highway Tunnel Ventilation Fan
The Highway Tunnel Ventilation Fan is a professional ventilation solution designed for modern road tunnel projects.
It provides reliable airflow control for:
Highway tunnels
Expressway tunnels
Urban road tunnels
Mountain tunnels
Underwater tunnels
The main purpose of tunnel ventilation is to:
Remove vehicle exhaust gases
Control carbon monoxide concentration
Maintain visibility
Improve driving safety
Provide emergency smoke control during tunnel fires
Modern tunnel ventilation systems commonly use jet fans and large axial ventilation fans according to tunnel length, traffic volume and ventilation design requirements.
3. Main Product Types
A. Highway Tunnel Jet Fan
Longitudinal Ventilation Fan
The tunnel jet fan is one of the most widely used ventilation devices for highway tunnels.
It is normally installed on:
Tunnel ceiling
Tunnel side wall
Underground passage structures
Working principle:
High Speed Jet Airflow
↓
Generate Thrust Force
↓
Move Tunnel Air Longitudinally
↓
Remove Polluted Air
The high-speed airflow generated by the jet fan transfers momentum to the surrounding tunnel air, creating longitudinal ventilation.
Advantages
Compact structure
Easy installation
No large ventilation duct required
Flexible operation
Low construction cost
