Description
The ebmpapst S4D500-AD03-01 is a high-performance industrial AC axial fan with a nominal voltage of 400/480 VAC and an impeller size of 500 mm, specifically engineered for demanding thermal management in large-scale condensers and industrial ventilation systems. Driven by a robust three-phase M4D110-GF external rotor motor with a maximum power consumption of 1220 W at 480 VAC (60 Hz) in a Delta (Δ) connection and 770 W in a Star (Y) connection, this unit features a heavy-duty ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with 5 backward-curved die-cast aluminum blades delivers a massive airflow of 11300 m³/h at 1570 RPM (60 Hz Δ) and 8120 m³/h at 1035 RPM (50 Hz Y), achieving high static efficiency across various wiring configurations. Constructed with an aluminum-cast rotor surface, an ABS plastic terminal box, and condensate discharge holes on both rotor and stator sides, this 15.5 kg fan unit provides a dependable and rugged cooling solution with IP54 protection and Class F insulation for cooling towers, dry coolers, and industrial AHU infrastructure at the end.
