Description
The ebmpapst K3G450-AZ30-01 is a high-performance 400 VAC (3-phase) EC Centrifugal Fan unit with a 450 mm RadiPac impeller, specifically engineered for mission-critical industrial ventilation and precision 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 5370 W and a Max. Current Draw of 8.3 A at a rated speed of 2750 RPM. This Industrial Frequency Converters compatible unit features a high-strength aluminium sheet impeller, galvanized steel inlet nozzle, and a 52.7 kg heavy-duty steel support structure with Dimensions of 630 x 630 x 483 mm. It achieves a Max. Air Flow of 8040.0 m³/h (4732.1 CFM) and a Max. Static Pressure of 152.15 mmH₂O (1492.0 Pa / 5.99 inAq) at its maximum load (ml) point. Integrating RS-485 MODBUS-RTU, an integrated PID controller, and VFD compatibility, this IP54-rated unit is optimized for extreme reliability and precise airflow modulation in demanding industrial environments. The ebmpapst K3G450-AZ30-01 centrifugal fan is the primary cooling component for server room precision air conditioning, large-scale ventilation systems, and industrial clean room systems requiring massive air volume and high-pressure stability in 400 VAC environments at the end.
