Road, Railway & Metro Fans

TLT-Turbo offers axial and jet fans for the construction, normal operations, and emergency operations of roads, railways, and metro tunnels. Since our first project in Spain in the 1960s, we continually incorporate the latest developments in fan design and manufacturing from other fields of application, such as mine ventilation and power stations, to deliver the safest and most efficient fans on the market.

Keeping users safe and comfortable

For more than 60 years, TLT-Turbo has kept tens of millions of tunnel users safe and comfortable during their travels. Our fans help regulate air quality by providing fresh and cool air or extracting contaminants such as exhaust fumes or brake dust. Our smoke extraction fans can withstand high temperatures in the undesirable event of a fire, thus providing safe evacuation conditions.

Our Offering

Tunnel & metro fans

Renowned for their unmatched reliability, our tunnel and metro fans consistently operate with efficiencies above 70% across a wide range of pressure and airflow requirements. We supply both unidirectional and bidirectional fans designed for exceptionally challenging environments, ensuring they perform optimally even under demanding conditions.

Jet fans

TLT-Turbo offers a variety of unidirectional and bidirectional jet fans. They generate thrust to accelerate the air’s in-tunnel velocity and boost circulation. Designed explicitly for tunnel ventilation, they can operate in exceptionally challenging environments and provide quick emergency smoke extraction at extremely high temperatures in reverse mode.

Tunnel construction fans

Our tunnel construction fans continuously and reliably provide the construction site with fresh air or evacuate dust and vehicle exhaust fumes until flow-through ventilation is established. They provide scalable performance and flexibility for safe tunneling development. Their rugged build allows them to operate in any condition, whether underground or on the surface.

Tunnel and metro fan maintenance, rebuilds, and upgrades

We support all our North American clients from our facility in Akron, Ohio. Our experienced engineers and field technicians are available for fan maintenance, rebuilds, and design upgrades to extend any fan’s service life.
