Jet Fans are compact axial fans designed for longitudinal ventilation in road tunnels, rail tunnels and underground environments. Thanks to their ability to generate aerodynamic thrust, they ensure air exchange and smoke control in the event of an emergency. They are available in unidirectional and fully reversible versions, with high-efficiency motors and certifications for operation under extreme conditions. Their robust structure and aerodynamic design ensure reliability, noise reduction and ease of installation even in confined spaces.

In tunnels and mines, Jet Fans play a crucial role in safety and operational continuity. Installed along the tunnel ceiling, they create a longitudinal airflow that dilutes harmful gases and dust, maintaining air quality during traffic flow or excavation phases. In the event of a fire, they ensure smoke control and visibility along escape routes, operating up to 300°C for two hours in accordance with EN 12101-3. Full reversibility allows the airflow to be adapted to emergency requirements, while their compactness reduces installation and maintenance costs.

JET series fans are available in both straight and angled versions, for the best compromise between size, spacing and power in new tunnels, and the best compatibility with existing layouts in the case of replacements.
