K3G400-PW03-01 ebmpapst 400VAC 400mm EC Centrifugal Fan

Description

The ebmpapst K3G400-PW03-01 is an ultra-high performance 400 V three-phase GreenTech EC centrifugal fan module from the RadiPac series, featuring a 400 mm backward-curved aluminum impeller integrated into a heavy-duty cubic support structure. Driven by the enhanced M3G112-IA motor with integrated electronics, this unit delivers a powerful airflow of 6360 m³/h and a significant pressure increase of 1239 Pa. Designed for mission-critical HVAC infrastructure, it features a sophisticated MODBUS V6.3 interface, an integrated PI controller, and configurable I/O for precise system integration. With its galvanized steel support plate and IP55-rated die-cast aluminum electronics, the K3G400-PW03-01 provides a smart, robust, and energy-efficient thermal management solution for data center cooling and high-pressure air handling units across an wide ambient temperature range of -40 °C to 40 °C.
