WG Motor 500-4D-550-S-G-415 550mm Three Phase Basket Cage Axial Fan
The WG Motor 500-4D-550-S-G-415 is a 550mm basket cage axial fan assembly suited to commercial refrigeration, HVAC and cooling equipment applications. Based on WG Motor’s matching YWF4D-550S-137/50-* platform, this fan is designed for high-volume axial airflow across condensers, evaporators and other heat exchange equipment.
With a three phase 380–480V AC motor, 4-pole speed profile, IP54 protection, Class F insulation and airflow up to 8585m³/h at 60Hz, it is a strong option for refrigeration service replacement and OEM-style fan applications where the physical fit and electrical specification match the equipment.
