Tunnel Ventilation System
Tunnel Ventilation Systems
| Fan Type | Capacity (HP) | Indicative Operating Cost |
|---|---|---|
| Axial Fans | 0.5 HP – 300 HP | x |
| Centrifugal Fans | 30 HP – 300 HP | x/5 |
Depending on project requirements and installation conditions, air can be transported through:
- Bore holes through the ground
- Flexible ventilation ducts
- Spiral ducts
- GI ducts for permanent installations
- Concrete passages for permanent installations
The appropriate air-transport method is selected based on tunnel length, airflow requirements, pressure losses, installation conditions, accessibility, and project lifecycle considerations.
Open Tunnel Ventilation
For open or large underground spaces, Jet Fan Ventilation Systems can be used to generate controlled longitudinal airflow and assist in smoke and fume movement.
Jet Fan Capacity: 0.5 HP to 60 HP
Jet fan systems can be configured for applications requiring efficient air circulation, smoke management, and ventilation in large underground spaces.
Applications
Our tunnel and underground ventilation solutions can be applied to:
- Underground infrastructure projects
- Lift irrigation schemes
- Water conveyance tunnels
- Large underground caverns
- Tunnelling and excavation projects
- Smoke and fume extraction systems
- Emergency and fire ventilation
- Fresh-air supply systems
- Experience in Underground Ventilation
Aura Solution has supplied underground ventilation systems for lift irrigation schemes across India, including projects such as GLIS-III, PRLIS-I, and RLIS.
Our experience enables us to develop ventilation arrangements that balance airflow performance, safety requirements, installation constraints, and long-term operating costs for demanding underground applications.
