WG Motor YWF4D-450S 450mm Three Phase Basket Cage Axial Fan
The WG Motor YWF4D-450S is a 450mm three phase external rotor axial fan designed for refrigeration, HVAC and commercial cooling equipment. It is suited to moving air across condensers, evaporators and heat exchange coils where strong axial airflow is required.
Based on WG Motor’s listed YWF4D-450S-102/60-* platform, this fan uses a 380–480V three phase AC motor, 4-pole speed profile, IP54 protection and Class F insulation. With airflow up to 5579m³/h at 60Hz, it is a practical replacement or OEM-style fan option for refrigeration equipment where the physical fit and electrical specification match the original fan.
