SDS Tunnel Jet Fan

SDS Tunnel Jet Fan
Product Overview
The SDS Tunnel Jet Fan is an axial-flow jet fan designed for longitudinal ventilation in road tunnels, highway tunnels, underground roads, transportation tunnels, and other large underground facilities.
By generating high-velocity airflow and jet thrust, the fan transfers momentum to the surrounding tunnel air and drives longitudinal airflow through the tunnel. It can be used for normal ventilation, pollutant removal, airflow control, and smoke management during fire emergencies.
EMS provides SDS Tunnel Jet Fans with customized airflow, jet thrust, motor power, reversible operation, high-temperature configuration, mounting systems, and electrical control solutions according to individual tunnel projects.
