S4D500-AM03-02 ebmpapst 400V/460V 500mm AC Axial Fan

Description

The ebmpapst S4D500-AM03-02 is a high-performance 3~ AC Axial Fan with a 500 mm impeller diameter, featuring the M4D110-GF external rotor motor. This industrial unit is highly versatile, operating at 400 VAC or 460 VAC with both Delta (Δ) and Star (Y) connection options. Based on the technical data, it delivers a maximum speed of 1640 RPM at 60 Hz (460V Δ) with a power input of 1060 W. The fan is designed with 5 blades made of press-fitted sheet steel blanks, sprayed with PP plastic for enhanced durability. It is ErP 2015 compliant with an efficiency grade of N 40.6 and an overall static efficiency of 33.4%. Rated at IP54 with Class F insulation and F4-1 humidity protection, the S4D500-AM03-02 is optimized for S1 continuous duty in large-scale condensers, heat exchangers, and industrial climate control systems.

Application
The ebmpapst S4D500-AM03-02 axial fan is a premier industrial thermal management solution designed for high-capacity heat dissipation in environments such as commercial refrigeration condensers, large-scale oil coolers, and air-cooled heat exchangers. Its “A” airflow direction and robust IP54-rated construction make it suitable for outdoor installation where exposure to moisture and dust is expected. The press-fitted steel blades with PP coating provide superior structural integrity while maintaining the aerodynamic performance needed to move nearly 6000 m³/h of air. With 400V/460V versatility and integrated thermal overload protection, this 500 mm fan ensures mission-critical reliability for power generation infrastructure, large-scale HVAC systems, and manufacturing process ventilation.
