K3G500-PA23-71 ebmpapst 380-480V 500mm EC Centrifugal Fan

Description

The ebmpapst K3G500-PA23-71 is a heavy-duty, high-performance 3-phase EC Centrifugal Fan module featuring a 500 mm backward-curved aluminum impeller. Driven by the M3G150-FF (Size 150) GreenTech EC motor, this 38.7 kg unit is a central component for high-capacity air handling units (AHU) and large-scale industrial ventilation. Operating on a 380-480 VAC supply, it delivers exceptional performance with a power consumption of 3450 W at a rated speed of 1910 RPM. This RadiPac unit is built for maximum durability, utilizing sheet aluminum for the 7-blade impeller, galvanized sheet steel for the support plate and inlet nozzle, and a die-cast aluminum electronics housing supported by black-painted steel brackets. With integrated MODBUS-RTU control, a built-in PID controller, and IP55/H1 protection, the K3G500-PA23-71 provides a mission-critical, IE5-level efficiency cooling solution for global 400V infrastructures requiring high static pressure and 24/7 operational reliability.
