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

Description

The Ziehl-Abegg RH56M-6DK.6K.1R is a professional-grade AC backward-curved centrifugal fan featuring the bionic Cpro composite impeller for optimized aerodynamic efficiency and silent operation. This 560 mm unit is equipped with a versatile three-phase external rotor motor that supports dual-voltage configurations (230V/400V) and dual-frequency operation (50/60 Hz). Delivering a nominal 0.63 kW at 900 RPM (50 Hz), it is specifically engineered for high-temperature environments, maintaining operational stability up to 70 °C. Its IP54-rated construction and high-performance blue composite blades ensure long-term durability and energy-efficient performance in specialized air handling units and industrial heat exhaustion systems.
