SKU CH-8TP4-NBZDJ MPN R4D500-AT03-08Motor

Centrifugal case fan with a 500mm blade diameter, 400V supply, 3.0A current and 1430W motor running at 1375rpm

  • High airflow up to 35000 m³/h for demanding cooling
  • Centrifugal design with 500 mm blade diameter moves large air volumes
  • External rotor motor enables compact 1430 W performance at 1375 rpm
  • 400 V three-phase power at 3.0 A suits industrial cabinet installations
  • 100 % speed control via analog or serial interface for precise regulation

Industrial centrifugal fan for rack airflow

This 500 mm centrifugal fan from ebm-papst is built for cabinet and chassis installations that demand high-volume air movement. It runs on 400 V three-phase power and draws 3.0 A at full load, making it suitable for industrial rack cooling and telecommunications enclosures.

External-rotor motor removes need for scroll housing

The backward-curved impeller integrates the motor inside the rotor, providing direct cooling and a compact footprint without a separate scroll. Speed is fully controllable via analog or serial interface, and the plug-and-play design simplifies integration into existing control loops.

Delivers up to 35000 m³/h at 1430 W

At 1375 rpm the fan moves large air volumes for dense equipment racks, while the 1430 W motor rating defines the thermal ceiling. It is not suited for low-voltage desktop builds or applications requiring forward-curved blades with a dedicated housing.

Questions about this item

Will the 500mm impeller or motor bearings need scheduled replacement?

The external rotor motor sits inside the impeller, so motor cooling is continuous and bearing wear is minimised by the compact design.

At continuous 1375 rpm and 1430 W, which limit appears first — thermal or airflow?

Airflow reaches up to 35000 m³/h before the motor hits its thermal ceiling at the rated 400 V and 3.0 A.

How loud and hot does the 400 V centrifugal fan run during all-day operation?

Low-noise forward-curved blades and forced electronic cooling keep sound and temperature low even at full 1430 W load.
