Metro Tunnel Jet Fans – YFTNV

Its design integrates high-efficiency silencers at both ends, optimizing sound control without sacrificing thrust. It is a direct-drive solution, ensuring immediate response and high availability. Furthermore, its smooth rotational reversibility (reaching nominal speed in less than 30 seconds) and fire resistance (continuous operation at $280^\circ\text{C}$ for 60 minutes per CCCf certification) make it a safety standard for emergency smoke evacuation.

Competitive Advantages

• Fire resistance: Certified to operate under fire conditions ($280^\circ\text{C}$ for 1 hour) without structural or electrical failure.
• Reversibility: Ability to quickly reverse airflow direction, essential for smoke management.
• Simplified maintenance. Includes grease extension tubes running from the nipple to the exterior housing, facilitating maintenance in tunnels.
• High efficiency: Impeller with airfoil blades to maximize thrust and minimize energy consumption.
• Durabilidad extrema: Surface finish via hot-dip galvanizing or special corrosion-resistant coating.
