High-Performance Tunnel Ventilation Fan – Axial Flow Jet Fan for Underground Projects (2025)

Product Introduction：SDF/SDS tunnel ventilation Fan

 

The Tunnel Ventilation Fan is a heavy-duty axial flow jet fan designed for large-scale underground ventilation systems. Engineered with advanced aerodynamics, it delivers high-volume airflow, reliable pressure performance, and energy-efficient operation, ensuring safe and controlled environments in tunnels, subways, and underground facilities.

Manufactured to international standards (ISO 5801, AMCA 210, CE, ATEX/IECEx), this fan is suitable for continuous operation in demanding civil and infrastructure projects.

 

Key Features

 

🔹 High Airflow & Static Pressure

Capable of delivering 20,000 – 300,000 m³/h airflow and 300 – 2,000 Pa static pressure, ensuring efficient ventilation across long tunnel sections.

🔹 Axial Jet Fan Design

Optimized aerofoil blades and streamlined casing provide stable, uniform air distribution with high efficiency and reduced turbulence.

🔹 Low Noise Operation

Incorporates acoustic dampening, precision-balanced impellers, and optional silencers to achieve noise levels of ≤ 75 dB(A), compliant with occupational safety standards.

🔹 Explosion-Proof & Fire-Resistant Options

Available with Ex d IIB T4 explosion-proof motors and F400 fire-rated configurations for enhanced safety in hazardous or high-temperature environments.

🔹 Durable & Reliable Construction

Constructed with hot-dip galvanized steel or epoxy-coated housing for corrosion resistance. Bearings and motor system are designed for 40,000+ hours of continuous duty.
