Ventilation in tunnels presents unique challenges due to confined spaces, vehicle emissions, and emergency preparedness requirements. Tunnel Ventilation Fans are critical components in ensuring safe and breathable air for both everyday operations and emergency scenarios.
Purpose of Tunnel Ventilation Fans
Tunnel ventilation systems are designed to:
- Maintain acceptable air quality by removing pollutants such as carbon monoxide, nitrogen oxides, and particulate matter generated by vehicular traffic.
- Control temperature and humidity levels within the tunnel environment.
- Provide effective smoke extraction and visibility control during fire incidents to facilitate safe evacuation and firefighting operations.
- Ensure compliance with international safety and environmental standards in tunnel infrastructure.
