K3G500-AP25-01 ebmpapst 400VAC 500mm EC Centrifugal Fan

Description

The ebmpapst K3G500-AP25-01 is a high-performance RadiPac EC centrifugal fan assembly engineered for superior energy efficiency and intelligent airflow management in large-scale HVAC systems. Driven by the M3G150-FF external rotor motor, this 500 mm unit is optimized for 3-phase 400 VAC operation, delivering a robust air volume of 8140 m³/h at its optimum efficiency point with a static efficiency of 66.5%. The construction features a 7-blade aluminum sheet impeller and a comprehensive support system including a hot-dip galvanised mounting plate and inlet nozzle. Its advanced electronics suite offers unmatched control flexibility, featuring RS485 MODBUS-RTU, an integrated PID controller, and dual sensor inputs (0-10 V and 4-20 mA). Built for S1 continuous operation with IP54 protection, the K3G500-AP25-01 incorporates comprehensive safety features such as phase failure detection, active motor current limitation, and thermal overload protection, providing a professional-grade, plug-and-play solution for air handling units and industrial ventilation.
