Ziehl-Abegg RH28M-2DK.3F.1R Centrifugal Fan Drive

Ziehl-Abegg RH28M-2DK.3F.1R Centrifugal Fan Drive is a centrifugal fan designed for inverter and drive cooling, featuring an external rotor AC motor and a backward-curved impeller for efficient airflow and reliable continuous-duty operation.

It runs on 400–460 VAC three-phase power at 50/60 Hz, delivering about 0.53 to 0.86 kW and drawing roughly 0.95 to 1.25 A as speed varies.

The 280 mm fan diameter supports typical airflow of around 2950 m³/h with a speed range of approximately 2750–3220 RPM, while offering IP10 protection and Class 155 insulation for use in demanding industrial environments.

Commonly integrated into Siemens VFDs, inverter cabinets, electrical enclosures, HVAC systems, and other industrial automation equipment where high airflow and efficient heat dissipation are critical.
