The SDS Jet Fan is a high-efficiency ventilation solution specifically designed for tunnel ventilation systems, underground parking garages, and large enclosed spaces. Installed directly beneath tunnel ceilings or parking structures, the fan generates a high-speed jet airflow that induces surrounding air movement, creating effective longitudinal ventilation without the need for extensive ductwork.
Based on the principle of impulse ventilation, the SDS Jet Fan transfers momentum to the surrounding air, pushing fresh air throughout the tunnel while removing vehicle exhaust gases, smoke, heat, and pollutants. Compared with traditional ducted systems, it reduces installation costs, saves space, and improves overall ventilation efficiency.
The SDS series is available in multiple models to meet different airflow and thrust requirements, making it a reliable solution for modern tunnel ventilation and smoke control projects.
