Description
The ebmpapst K3G450-PB29-N1 is an ultra-high-performance 400 VAC (3-phase) EC Centrifugal Fan unit with a 450 mm RadiPac impeller, specifically engineered for mission-critical industrial ventilation and large-scale Air Handling Units (AHU). Driven by the robust M3G150-IF motor, this unit operates within a 380 – 480 VAC range, delivering a massive Max. Power Consumption of 6800 W and a Max. Current Draw of 10.3 A at a rated speed of 2800 RPM. This Industrial Frequency Converters compatible unit is constructed with a high-strength sheet aluminum impeller, galvanized sheet steel inlet nozzle, and a 45.2 kg heavy-duty steel support structure with Dimensions of 630 x 630 x 540 mm. It achieves a Max. Air Flow of 9035.0 m³/h (5317.8 CFM) and a Max. Static Pressure of 178.35 mmH₂O (1749.0 Pa / 7.02 inAq) at its maximum load (ml) point. Featuring advanced technical integration including RS-485 MODBUS-RTU V6.4, an integrated vibration sensor, and VFD compatibility, this IP55-rated unit is optimized for extreme reliability and precise airflow modulation in demanding industrial environments. The ebmpapst K3G450-PB29-N1 centrifugal fan is the primary cooling component for large-scale industrial air handling units (AHU), server room precision air conditioning, and high-pressure ventilation systems requiring massive air volume and high energy efficiency in 400 VAC environments at the end.
