Application
The Ziehl-Abegg RH50M-6DK.4I.1R (Article No. 123670) is a versatile, mid-range AC centrifugal fan engineered for high-performance air displacement in compact Air Handling Units (AHU), commercial rooftop ventilation, and industrial cabinet cooling. Featuring a 500 mm backward-curved impeller and a lightweight 12 kg design, this unit is specifically optimized for applications requiring a balance of high airflow (up to 7,850 m³/h) and exceptionally quiet operation, provided by its 6-pole motor architecture.

The fan’s ability to operate continuously at 70°C ambient temperatures makes it an ideal choice for demanding environments such as industrial process drying, heat exchangers, and high-temperature kitchen exhaust systems. With dual-frequency (50/60 Hz) and multi-voltage (230/400V or 265/460V) support, it offers a global air-moving solution for mission-critical infrastructures including pharmaceutical clean rooms, hospital isolation wards, and noise-sensitive office building climate control. Its IP54 protection and robust “Made in Germany” build quality ensure long-term, maintenance-free reliability in 24/7 S1 continuous-duty cycles.
