INFINAIR
Metro Fan-Vane Axial Type – YFMRT
The YFMRT is a high-performance axial vane fan designed specifically for tunnel ventilation, subways, large construction projects, and dams. With massive airflow capacities and a construction engineered for emergency conditions, this equipment is the industry standard for safety and air control in underground infrastructure.
Equipment Overview
The YFMRT fan is a robust solution that integrates advanced aerodynamic technology from the aerospace industry. Its design, optimized through CFD (Computational Fluid Dynamics) simulation and verified via stress testing (FEA), ensures safe operation even during critical smoke evacuation situations.
