SDS tunnel jet fan is a new product developed by our company using advanced technology and processes. The company has conducted extensive research on subway, highway, railway tunnel and other projects across the country, consulted experts from tunnel design institutes and tunnel installation companies, and mastered relevant information such as first-hand fan usage conditions and product technical requirements. The efficiency of the developed tunnel jet fan product is significantly better than that of conventional axial flow fans, and its performance indicators, corrosion resistance, high temperature resistance, reliability and other technical requirements are fully suitable for the use of various subways and tunnels, optimizing the system engineering support.

　　Tunnel jet fanThere are two ventilation forms: unidirectional jet fan SDS (K) and reversible bidirectional jet fan SDS (R). The forward and reverse switching time of reversible jet fans is extremely important in emergency situations, and SDS (R) reversible jet fans can switch to the rated fan speed within 30 seconds.

The specifications of SDS tunnel jet fans range from Ø 630mm to Ø 1600mm, with a thrust of up to 3500N. The air volume can be adjusted by changing the number and angle of blades to meet the requirements. Suitable fans can be selected for any load and working condition
