The NSL jet fan generates high-velocity air jets to push smoke or air along tunnels without ducts. Thrust-oriented design; airflow 3,240–187,920 m³/h. Power 0.75–55 kW at speeds of 975–2,900 r/min. IP55 / Class H.
Product Advantages
-
High thrust: Designed specifically to overcome tunnel resistance and induce airflow.
-
Energy efficient: Optimized nozzle and impeller reduce power per unit thrust.
-
Low noise: Only 50–60 dB(A), critical in tunnel environments.
- Reversible option: Bidirectional models available for smoke control.


Application Scenarios
- Road and railway tunnels
- Underground parking ventilation
- Mine airway boosting
- Large atrium smoke extraction



FAQ
Q1: How many jet fans are needed for a tunnel?
– Depends on tunnel length and cross-section; we provide CFD-based recommendations.
Q2: Can it run in reverse?
