R4E400-AR05-06 ebmpapst 230V 400mm AC Centrifugal Fan

Description

The ebmpapst R4E400-AR05-06 is a heavy-duty single-phase AC centrifugal fan with backward-curved blades, powered by the high-torque M4E094-FA external rotor motor. This 400 mm unit is engineered for high-pressure air displacement, delivering a static efficiency of 43% (reaching a grade of N62 per 2015 standards). Unlike standard plastic models, it features a robust 6-blade impeller constructed from aluminum plate and a black-painted rotor surface, ensuring maximum durability for S1 continuous operation in demanding environments. Optimized for 230 VAC operation, it requires an 8 µF capacitor and supports a wide ambient temperature range down to -40 °C. Equipped with premium ball bearings, IP54 protection, and internal thermal overload monitoring via a temperature wire (TW), the R4E400-AR05-06 provides a professional-grade, high-capacity cooling solution for industrial ventilation and HVAC systems.
