Subway & Tunnel Ventilation Solutions by Yueyu
How Can Subway and Tunnel Ventilation Be Safer and More Efficient?
Subways and tunnels are enclosed spaces requiring efficient ventilation to ensure safety and comfort. Key needs include rapid smoke extraction during fires, dust and PM2.5 control during construction and operation, and proper airflow to prevent the “piston effect.” With rapid underground development, high-efficiency centrifugal fans have become essential. Yueyu leverages its strategic location in the Pearl River Delta to support major infrastructure projects.

Yueyu Fans Meet Diverse Needs
● Operational Ventilation: Continuous air exchange to control CO₂ levels using Yueyu high-volume centrifugal fans (YYLA).
● Emergency Smoke Extraction: Rapid reverse-flow discharge of high-temperature smoke.
● Construction Dust Control: High dust tolerance and continuous operation with Yueyu dust-resistant centrifugal fans (YYDF).
● Equipment Room Cooling: Low-noise, energy-efficient operation for optimal temperature control.
Product Core Advantages
Yueyu fans combine four key technologies to handle demanding conditions
✓ Wear & Corrosion Resistance: Plasma-welded impellers with hard-alloy coating resist particle erosion; casings use imported corrosion-resistant materials for humid tunnel environments.
✓ High-Temperature Capability: Bearing housings feature independent cooling, supporting short-term smoke exhaust up to 250°C in compliance with fire safety standards.
✓ Energy Efficiency: High-pressure aerodynamic design reduces energy consumption by 15% and increases air pressure by 30% compared to conventional models.

Industry Application Cases
Case 1 – Guangzhou-Foshan Metro Ventilation Upgrade:
12 high-temperature reversible fans (YYAF series) installed at an underground transfer station for bidirectional smoke exhaust; dynamically balanced impellers ensure vibration ≤4.5 mm/s.
Case 2 – Zhujiang Tunnel Construction Dust Control:
Custom dust extraction centrifugal fans with pre-filters handle over 80 tons of dust daily; impeller lifespan extended to 18 months.
Case 3 – Shenzhen-Zhongshan Channel Equipment Room Ventilation:
Low-noise box-type centrifugal fans maintain sound levels below 75 dB(A); energy-saving mode reduces power consumption by over 20%.
