RH56M-4DK.6K.1R Ziehl-Abegg 230/400V AC Centrifugal Fan

Description

The Ziehl-Abegg RH56M-4DK.6K.1R is a specialized AC backward-curved centrifugal fan featuring a high-efficiency 570 mm bionic Cpro composite impeller. Engineered for medium-duty industrial applications, this unit balances a lightweight 22 kg design with a robust 4-pole external rotor motor. Supporting dual-voltage (230/400V) configurations, it delivers a precise 1230 RPM at 50Hz with a nominal power input of 0.80 kW. Designed with an IP54 protection rating and high-temperature tolerance up to 70 °C, this fan provides exceptional aerodynamic stability and energy efficiency for modular air handling units and precision cooling systems where weight and airflow performance are critical.
