G3G280-BR04-M7 ebmpapst 400V 280mm EC Centrifugal Fan

Description

The ebmpapst G3G280-BR04-M7 is a high-performance 380-480 V three-phase GreenTech EC centrifugal fan module featuring a 280 mm backward-curved RadiCal impeller and a robust galvanized sheet steel scroll housing. Driven by the M3G084-DF external rotor motor with integrated electronics, this unit delivers an air flow of 1505 m³/h and a static pressure increase of 692 Pa. The impeller, constructed from high-strength PP plastic, is aerodynamically optimized for low-noise operation. Designed for S1 continuous duty, it features an RS-485 Modbus RTU interface, an integrated PID controller, and comprehensive motor protection including phase failure detection. This unit is a key thermal management component for industrial equipment, specifically associated with Siemens part number ASE44686678, operating reliably within an ambient temperature range of -25 °C to 60 °C.
