Description
The ebmpapst W4D500-ZL09-01 is a versatile industrial AC axial fan with a nominal voltage of 400/480 VAC and dimensions of 600 x 600 x 256 mm, engineered for high-efficiency thermal management in refrigeration and industrial ventilation. Driven by a multi-phase M4D110-GF external rotor motor with power ratings from 475 W to 1090 W depending on wiring configuration (Δ/Y), this unit features a heavy-duty dual ball bearing system designed for long-term mechanical stability and continuous S1 duty. Its aerodynamic design with a 500 mm impeller, constructed from PP plastic and galvanized sheet-metal, delivers a robust airflow of 5810 m³/h at its optimum efficiency point while maintaining high static pressure capability. Built with a PP plastic fan housing and a terminal box for flexible electrical hookup, this 14.58 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 units at the end.
