NSL-63R low noise axial flow jet fan is a popular impulse ventilation unit widely used in highway tunnels, underground parking lots and underground enclosed spaces. Adopting optimized aerodynamic impeller and silencer structure, it effectively reduces running noise while maintaining stable jet thrust, helping circulate air, discharge carbon monoxide and exhaust gas efficiently.
Different from traditional duct ventilation systems, this jet fan saves installation space and reduces overall engineering cost. It can form a complete air circulation system without complicated duct layout, suitable for both daily air renewal and smoke control in emergency conditions.
We provide full OEM and ODM customization service. You can adjust fan thrust, voltage, rotation direction, mounting bracket and surface treatment according to your project drawing and site requirements. Each NSL-63R jet fan undergoes strict performance testing before delivery, featuring solid welding, reliable motor, easy installation and low maintenance.
This low-noise jet fan is a preferred ventilation solution for tunnel contractors, parking system builders and ventilation engineering suppliers.
