K3G280-BD14-N2 ebmpapst 400VAC 280mm EC Centrifugal Fan

Description

The ebmpapst K3G280-BD14-N2 is a specialized 380-480 V three-phase GreenTech EC centrifugal fan module from the RadiPac series, engineered to meet rigorous railway and industrial standards. Featuring a 280 mm backward-curved aluminum impeller within a robust cubic support structure, it is powered by the M3G084-GF motor, delivering 900 W of performance at speeds up to 3140 RPM. This module is uniquely certified to EN 45545-2 (HL3) for fire protection and EN 50155 for electronic equipment used on rolling stock, making it an ideal thermal management solution for railway technology and heavy-duty industrial AHU systems. Equipped with an RS-485 Modbus RTU interface, integrated PID controller, and emergency operation mode, it ensures maximum safety and reliability across an extreme ambient temperature range of -40 °C to 60 °C.
