K3G450-PB29-L1/F01 ebmpapst 400V 450mm EC Centrifugal Fan

Description

The ebmpapst K3G450-PB29-L1/F01 is a mission-critical RadiPac EC centrifugal fan assembly featuring a 450 mm aluminum impeller and a heavy-duty support bracket. Powered by the M3G150-IF motor, this 3-phase unit operates at 400 VAC (380 – 480 VAC range), delivering a massive 6800 W output at 2800 RPM. The fan is integrated into a robust support structure with dimensions of 630 x 630 x 536.5 mm, providing a stable footprint for high-capacity industrial installations. The /F01 variant integrates advanced factory-customized electronics, including MODBUS V6.4 RTU communication and a high-precision vibration sensor for real-time condition monitoring. Achieving a static overall efficiency of 68.8% (ErP 2015 N70.7), this 45.1 kg powerhouse is capable of moving 9035 m³/h (5318 CFM) at a high pressure increase of 1749 Pa (7.02 inAq), providing an intelligent thermal management solution for large-scale AHU FanGrids and data center cooling towers.
