⚙ Product Description

SWF Series: High-Efficiency Mixed-Flow Ventilation Fan

The SWF fan features a unique conical hub and twisted blades. As air enters, it is deflected diagonally, increasing the pressure through both centrifugal force and axial acceleration. This "hybrid" design allows the fan to overcome high resistance in long ducting systems while maintaining a much smaller footprint than traditional centrifugal units.

✔

Superior Pressure Performance: Specifically engineered to provide higher static pressure than standard axial fans.

✔

Aerodynamic Mixed-Flow Impeller: Optimized via CFD for smooth airflow transition and high mechanical efficiency.

✔

Ultra-Low Noise Operation: Significantly quieter than axial fans of the same air volume.

✔

Compact Inline Design: Direct pipeline installation saves mechanical room space.

✔

Robust Construction: High-strength galvanized or cold-rolled steel with corrosion-resistant coating.
