Description
The ZIEHL-ABEGG RF22P-2DD.5H.1R is a high-performance 3-phase AC Centrifugal Fan with a 225 mm impeller, specifically engineered for intensive thermal management in industrial frequency converters and high-density power conversion systems. Driven by a high-torque external rotor motor with THCL 155 (Class F) insulation and IP54 protection, this unit features flexible power ratings up to 1.55 kW at 480 V (60 Hz). Operating at a high rated speed of 2850 RPM, it requires a significant Minimum Static Pressure (PsF min. 1000 Pa) at 60 Hz to ensure optimal motor cooling and operational stability. Constructed with a heavy-duty galvanized sheet steel impeller and a rugged die-cast aluminum motor housing, this 17.0 kg German-engineered unit ensures maximum mechanical stability and long-term performance for mission-critical industrial applications at the end.
