Description
The ZIEHL-ABEGG FB063-SDK.4I.V4S is a high-performance 400VAC three-phase AC Axial Fan featuring 630 mm aerodynamic aluminum sheet blades and a high-torque external rotor motor, specifically engineered for mission-critical cooling in Industrial Frequency Converters and specialized AHU systems. Driven by a precision-balanced motor with maintenance-free ball bearings and moisture/hot climate protection, this 13.00 kg unit operates at 400 VAC across 50/60 Hz frequencies using a Delta/Star (D/Y) connection to provide multi-speed flexibility, delivering a Max. Power Consumption of 0.72 / 0.47 kW (50Hz) and 0.93 / 0.52 kW (60Hz). This High-performance unit features a 4-blade aluminum impeller achieving a Max. Air Flow of 11500.0 / 9200.0 m³/h (6768.4 / 5414.7 CFM / 191.67 / 153.33 m³/min) at 50Hz. Featuring a “Made in Germany” robust construction with integrated thermal contacts (TB) for motor protection and high-grade L-TI-0596 powder coating, this IP54-rated fan is optimized for environments requiring high reliability and industrial-grade corrosion resistance in VFD systems at the end.
