Description
The ebmpapst S4D450-AO14-01 is a high-performance 400VAC three-phase AC Axial Fan featuring 450 mm specialized aerodynamic PP plastic blades and a high-torque 4-pole external rotor motor, specifically engineered for mission-critical cooling in Industrial Frequency Converters and large-scale ventilation systems. Driven by a precision-balanced motor with maintenance-free ball bearings and moisture protection (Humidity class F4-1), this 10 kg unit operates at 400 VAC using a Delta/Star (Δ/Y) connection to provide dual-speed flexibility across multiple frequencies, delivering a Max. Power Consumption of 480 / 340 / 690 / 400 W and a Max. Current Draw of 0.98 / 0.58 / 1.20 / 0.72 A at a rated speed of 1360 / 1110 / 1510 / 1060 RPM. This High-performance unit features a 5-blade PP plastic impeller with “V” direction airflow, achieving a Max. Air Flow of 4530.0 / 4980.0 m³/h (2666.3 / 2931.2 CFM / 75.50 / 83.00 m³/min) and a Max. Static Pressure of 14.28 / 10.20 mmH₂O (140.0 / 100.0 Pa / 0.56 / 0.40 inAq). Featuring a robust construction with an ABS plastic terminal box and a steel guard grille coated in black plastic (RAL9005), this IP54-rated fan is optimized for environments requiring high reliability and industrial-grade airflow in VFD systems at the end.
