SDS Tunnel Jet Fan

Our SDS series tunnel jet fan is a high-performance axial blower specially engineered for tunnel, subway and underground roadway ventilation. Built for high static pressure output, it delivers stable, powerful thrust to circulate fresh air and exhaust smoke efficiently in confined underground spaces.

Equipped with variable pitch adjustable blades, the fan allows flexible airflow and thrust tuning to match different project requirements. This aerodynamic design optimizes energy consumption, greatly cutting your long-term operating cost while maintaining reliable ventilation performance.

Constructed with heavy-duty carbon steel casing and reinforced impeller, this tunnel jet blower runs steadily under harsh underground conditions with low vibration and extended service life. The electric motor adopts IP55 protection grade, waterproof and dustproof for continuous 24-hour operation.

We provide full OEM and ODM customization service. You can adjust blade angle, thrust, power, painting, logo and installation structure to fit highway tunnels, railway tunnels, metro systems and underground mining projects.

Suitable for longitudinal ventilation, smoke extraction, air renewal and emergency smoke control. Strict quality inspection before shipment, with complete technical support and after-sales guidance for your engineering bidding and installation.
