Fans RH50M-6DK.4I.1R 60W 1090 rpm 6500 m3/h fan

SKU CH-YMK8-CRKYH

Industrial axial fan delivers 6500 m³/h airflow at 1090 rpm with a 60 W motor

  • Air Flow20-25 CFM
  • High airflow capacity with 6500 m3/h maximum volume
  • Low power draw at 60W for efficient operation
  • Quiet running at 79 dB noise index
  • Wide temperature tolerance from -20 to +70°C
  • Maintenance-free double ball bearings for long life

Industrial frequency-converter cooling fan

The Ziehl-abegg RH50M-6DK.4I.1R is built for three-phase 400 V environments such as Siemens frequency converters. It delivers 6500 m3/h maximum air volume at 1090 rpm while drawing 60 W, making it suitable for industrial drive cooling and similar continuous-duty applications.

Sustained-load behaviour

Maintenance-free double ball bearings support continuous operation across an ambient range of -20 to +70 °C. The motor runs at 60 Hz with a noise index of 79 dB and can develop up to 400 Pa of static pressure, so airflow remains stable during prolonged high-temperature duty cycles.

Galvanised steel construction and mounting

The impeller diameter is 500 mm, housed in galvanised steel plate and metal for corrosion resistance in harsh environments. The three-phase wiring and fixed-speed design imply direct integration into existing converter cabinets without additional speed-control electronics.

Questions about this item

How loud is the RH50M-6DK.4I.1R fan at 1090 rpm?

The noise index is 79 dB while the impeller runs at 1090 rpm, so expect a noticeable hum in a quiet room but it is typical for a 60 W industrial fan.

What power supply does the RH50M-6DK.4I.1R require?

It needs a three-phase 400 V supply with a ±10 % tolerance and a 60 Hz frequency to operate correctly.

Will the 500 mm impeller fit inside a legacy Siemens frequency converter cabinet?

The fan is built for Siemens frequency converters and the 500 mm diameter matches the original mounting pattern used on those units.
