FB050-VDK.4I.V4S ZIEHL-ABEGG 400V AC Axial Fan 500mm

Description

The ZIEHL-ABEGG FB050-VDK.4I.V4S is a High-Performance AC Axial Fan with pressed-steel blades, measuring 500 mm in diameter. It operates on 3∼400 V±10% and supports dual-speed operation (Delta/Star) at 50 Hz and 60 Hz. At 50 Hz, it delivers 0.82 kW Input Power and 1.50 A Current at 1,330 RPM (Δ connection), and 0.55 kW and 0.95 A at 1,030 RPM (Y connection).At 60 Hz nominal, it delivers 1.10 kW Input Power and 1.90 A Current at 1,400 RPM (Δ connection), and 0.60 kW and 1.00 A at 980 RPM (Y connection).The fan is optimized for installation in short nozzles and is widely used in refrigeration, air-conditioning, and general ventilation systems requiring precise speed control and robust performance.
