S4D500-8317073686 ebmpapst 400V 500mm AC Axial Fan

Description

The ebmpapst S4D500-8317073686 is a heavy-duty 500 mm 3-phase AC axial fan powered by the high-torque M4D110-GF motor, engineered for high-capacity industrial cooling and ventilation. This unit is optimized for dual-performance profiles via Delta (Δ) or Star (Y) wiring configurations, delivering a maximum speed of 1325 RPM and 820 W power consumption in Delta mode. The fan features a robust 5-blade sheet aluminum impeller and a cast aluminum rotor surface, ensuring exceptional structural integrity for S1 continuous operation. Designed for harsh environments, it carries an IP54 protection rating and can operate in extreme ambient temperatures ranging from -40 °C to 60 °C. With its integrated thermal overload protection and vibration-damped ball bearing system, the S4D500 provides a reliable, high-pressure air-moving solution for industrial condensers and large-scale HVAC systems.
