R3G280-RP54-B1 ebmpapst 230V 280mm EC Centrifugal Fan

Description

The ebmpapst R3G280-RP54-B1 is a high-performance EC Centrifugal Fan powered by the M3G084-FA motor, featuring a 280 mm backward-curved impeller designed for superior aerodynamic efficiency and pressure development. Operating on a 1-phase 230 VAC supply with an extended voltage range of 200 – 277 VAC, this unit consumes 705 W and draws 3.1 A to achieve a nominal speed of 2880 RPM. The fan is constructed with a 6-blade PP plastic impeller and a die-cast aluminum electronics housing, achieving an overall static efficiency of 61.8% in compliance with ErP 2015 standards. Weighing 5.3 kg and rated at IP54, the R3G280-RP54-B1 integrates advanced digital features including active PFC, RS-485 MODBUS-RTU, and a programmable control interface for 0-10V or 4-20mA sensors, making it an ideal intelligent thermal solution for high-static pressure applications in cleanrooms, server cooling, and industrial ventilation.

Application
The R3G280-RP54-B1 is specifically engineered for high-static pressure environments in precision air conditioning units and decentralized ventilation systems where its 2880 RPM backward-curved impeller and 705 W EC motor provide the necessary force to overcome high-resistance filtration, while the integrated MODBUS-RTU and sensor inputs allow for autonomous, energy-efficient pressure control in 230 VAC cleanroom filter fan units (FFU) and industrial cabinet cooling modules that demand a 5.3 kg compact design and reliable performance in ambient temperatures down to -25 °C.
