TYPES OF FANS USED IN FIRE TUNNEL VENTILATION
•Jet fans: Generate air movement in the tunnel,
ensuring a minimum speed throughout the entire section
•Axial fans: Ensure a minimum extraction flow
overcoming the load losses of the circuit

TYPES OF FANS USED IN FIRE TUNNEL VENTILATION
JET FANS
They are used in longitudinal ventilation, and in somecases, as support for the semi-transversal or transversal ventilation
• In the second case, they help axial fans of the semi-
transversal or transversal ventilation to guide the smoke
