S4D630-BR01-02 ebmpapst 400V 630mm AC Axial Fan

Description

The ebmpapst S4D630-BR01-02 is a high-capacity industrial AC axial fan with a nominal voltage of 400 VAC and an impeller size of 630 mm, specifically engineered for demanding thermal management in large-scale refrigeration and industrial cooling systems. Driven by a robust three-phase M4D110-IA external rotor motor with a power consumption of 1250 W in Delta (Δ) configuration and 840 W in Star (Y) configuration at 50 Hz, this unit features a heavy-duty ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with 5 blades, constructed from a PP plastic-sprayed aluminum insert, delivers a powerful airflow reaching 8830 m³/h at its optimum efficiency point while maintaining an overall static efficiency of 37%. Built with a cast aluminum rotor surface and a black plastic-coated steel guard grille, this 16.6 kg fan provides a dependable and weather-resistant cooling solution with IP54 protection and H2 environmental class for industrial condensers, dry coolers, and large-scale HVAC infrastructure at the end.
