R3G500-AP25-01 ebmpapst 400VAC 500mm EC Centrifugal Fan

Description

The ebmpapst R3G500-AP25-01 is a high-performance 380-480 V three-phase GreenTech EC centrifugal fan from the RadiPac series, featuring a 500 mm backward-curved aluminum impeller. Driven by a powerful M3G150-FF external rotor motor with integrated electronics, this unit achieves a maximum airflow of 8140 m³/h and an impressive static efficiency of 66.7%. The fan is engineered for intelligent thermal management, featuring a built-in PID controller, RS-485 Modbus RTU interface, and active power limiting for optimal energy consumption. With its robust IP55-rated die-cast aluminum electronics housing and maintenance-free ball bearings, the R3G500-AP25-01 provides superior reliability and precision speed control for large-scale industrial ventilation and mission-critical HVAC infrastructure.
