WG Motor 500-4E-550-S-137/50G 550mm Basket Cage Axial Fan
The WG Motor 500-4E-550-S-137/50G is a 550mm basket cage axial fan assembly suited to commercial refrigeration, HVAC and cooling equipment applications. Based on WG Motor’s matching YWF4E-550S-137/50-* platform, this fan is designed for high-volume axial airflow across condensers, evaporators and other heat exchange equipment.
With a single phase 220–240V AC motor, 4-pole speed profile, IP54 protection, Class F insulation and airflow up to 8595m³/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.
