SDF Tunnel Ventilation Fan

SDF Tunnel Ventilation Fan
Product Overview
The SDF Tunnel Ventilation Fan is a high-efficiency axial flow fan designed for forced ventilation and local ventilation in road tunnels, railway tunnels, underground construction projects, mining roadways, and other confined underground spaces.
The fan is commonly connected to a flexible ventilation duct to deliver fresh air to tunnel headings or working areas, while also supporting the removal of contaminated air, dust, heat, and construction fumes.
EMS provides SDF Tunnel Ventilation Fans in different diameters, airflow capacities, pressure levels, motor powers, and configurations according to tunnel length, ventilation distance, duct dimensions, system resistance, and project requirements.
