Product Description

High-Efficiency Tunnel Exhaust Axial Fan for Ventilation Systems—YBT Tunnel Exhaust Axial Fan

The YBT Tunnel Exhaust Axial Fan is a high-efficiency ventilation solution engineered specifically for modern tunnel construction and underground infrastructure projects. Designed with advanced aerodynamic technology and precision manufacturing, this axial flow fan delivers powerful and stable airflow to effectively remove dust, harmful gases, smoke, and heat from tunnels, ensuring a safe and breathable environment for workers and equipment.

Built with a rugged steel casing and anti-corrosive coatings, the YBT fan is capable of continuous operation in harsh environments, including high humidity, dusty air, and temperature fluctuations. Its high-strength aluminum or steel impeller blades are dynamically balanced to minimize vibration and noise, improving energy efficiency and prolonging operational life. The Tunnel Exhaust Axial Fan is available in a range of diameters and power configurations to meet different tunnel ventilation requirements.

The YBT series features optional explosion-proof motors and can be equipped with variable frequency drives (VFD) for smart airflow control. Its streamlined design, combined with a low-resistance impeller and guide vane system, ensures maximum ventilation performance with reduced energy consumption. With its robust design and easy installation, the YBT Tunnel Exhaust Axial Fan is widely used in road tunnels, subway tunnels, railway tunnels, and tunnel boring machine (TBM) projects.

Whether used for primary ventilation or emergency smoke extraction, this fan provides reliable, efficient, and safe operation throughout the lifespan of your project.
