Mixed Inline Duct Fan

Longwell Mixed Inline Duct Fans combine the efficiency of axial and centrifugal designs to achieve high pressure and strong airflow in compact systems. This hybrid structure makes them ideal for long duct runs, greenhouses, and commercial ventilation.
The fan’s inline configuration simplifies installation while reducing noise levels. Longwell uses aerodynamic blades and EC or AC motor options to deliver quiet, efficient, and durable air circulation for both residential and industrial uses.
