Description
The ZIEHL-ABEGG RF22P-2DK.3F.5R is a high-performance 400/460VAC three-phase AC Centrifugal Fan with a 225 mm backward-curved aluminum impeller, specifically engineered for mission-critical cooling in Industrial Frequency Converters and specialized power electronics. Driven by a high-torque external rotor motor with precision ball bearings, this 5.2 kg unit operates within a 400 – 460 VAC range across 50/60 Hz frequencies using a Star (Y) connection, delivering a Max. Power Consumption of 0.49 / 0.61 / 0.76 kW and a Max. Current Draw of 0.80 / 1.10 / 1.10 A at a rated speed of 2320 / 2230 / 2550 RPM. This High-performance unit features a specialized aerodynamic 7-blade aluminum impeller achieving a Max. Air Flow of 1150.0 / 1380.0 m³/h (676.8 / 812.2 CFM / 19.17 / 23.00 m³/min) and a Max. Static Pressure of 122.37 / 163.15 mmH₂O (1200.0 / 1600.0 Pa / 4.82 / 6.42 inAq). Featuring a robust construction with integrated thermal contacts (TB) for motor protection and a critical Min. Static Pressure requirement (PsF min. 620 Pa) at 460VAC 60Hz, this IP54-rated fan is optimized for environments requiring extreme high-pressure stability and long-term reliability in industrial VFD systems at the end.
