R3G400-FJ75-01 ebmpapst 400VAC 400mm EC Centrifugal Fan

Description

The ebmpapst R3G400-FJ75-01 is a high-efficiency 380-480 V three-phase GreenTech EC centrifugal fan featuring a 400 mm backward-curved RadiPac impeller made of high-strength PP plastic. Driven by the M3G112-EA external rotor motor, this unit achieves a maximum airflow of 5445 m³/h and an outstanding overall efficiency of 70.6%. Designed for intelligent climate control, it integrates an RS-485 Modbus RTU interface, a PID controller, and comprehensive protection features including line undervoltage and phase failure detection. With its IP55-rated die-cast aluminum electronics housing and specialized capability for occasional start-up at temperatures as low as -40 °C, the R3G400-FJ75-01 offers precision speed control and extreme reliability for industrial HVAC systems and demanding refrigeration applications.
