K3G560-PB31-71 ebmpapst 400VAC 560mm EC Centrifugal Fan

Description

The ebmpapst K3G560-PB31-71 is a high-performance 400 V three-phase GreenTech EC centrifugal fan module from the RadiPac series, featuring a 560 mm backward-curved aluminum impeller integrated into a robust 800 mm square support structure. This complete plug-and-play unit is equipped with a galvanized steel support plate, black painted steel support brackets, and a galvanized inlet nozzle, ensuring structural rigidity and optimized aerodynamics for large-scale ventilation. Driven by the powerful M3G150-IF motor with integrated electronics, it delivers a massive air flow of 10515 m³/h at a static efficiency of 71%. Featuring an RS-485 Modbus RTU interface, integrated PID controller, and comprehensive protection features including phase failure detection and soft start, the K3G560-PB31-71 is the definitive solution for high-capacity air handling units and data center cooling systems across an operating range of -25 °C to 40 °C.
