RD22P-4DW.4N.1R ZIEHL-ABEGG 400/690V 225mm Centrifugal Fan

Description

The ZIEHL-ABEGG RD22P-4DW.4N.1R is a high-capacity 400/690 V 3-Phase Industrial Centrifugal Fan with an impeller size of 225 mm, specifically engineered for intensive thermal management in heavy-duty industrial frequency converters and central ventilation systems. Driven by a high-torque external rotor motor with THCL155 (Class F) insulation and IP54 protection, this unit features a precise Max. Power Consumption of 1.00 kW and a Max. Current Draw of 2.2 A at 400 V (50 Hz). Operating at a rated speed of 1370 RPM (50 Hz), it provides superior static pressure capabilities and reliable air delivery under high-impedance conditions. Constructed with a heavy-duty galvanized sheet steel impeller and a rugged die-cast aluminum motor housing, this 20 kg German-made unit ensures maximum mechanical stability and long-term performance for mission-critical industrial applications at the end.
