Fans R4E400-AN09-06 centrifugal fan 400mm 230V 4 Pole Backward Curve

SKU CH-23MG-63G50

A 400 mm centrifugal fan with backward-curved blades runs on 230 V AC at 50/60 Hz, delivering up to 35000 m³/h airflow from a compact external-rotor motor

  • Operates on 230 V AC single-phase power
  • Delivers up to 35000 m³/h airflow
  • Runs at 1370 rpm on 50 Hz supply
  • Withstands ambient temperatures from -40 °C to 60 °C
  • Backward-curved impeller enables compact scroll-free design

Purpose-built airflow

This centrifugal fan is a 400 mm backward-curved impeller driven by an external-rotor AC motor rated for 230 VAC. It delivers up to 35000 m³/h of free air and operates from -40 °C to 60 °C without a separate scroll housing. The unit is new and sourced from ebm-papst Germany.

Who it suits

Installers needing high-volume, low-noise airflow in industrial cabinets, HVAC plenums or large enclosures will benefit from the compact motor-in-impeller design and forced electronic cooling. Buyers requiring a forward-curved blower with integrated housing, a different voltage or a variable-speed EC motor should look elsewhere.

Deciding specification

The motor runs at 1370 rpm on 50 Hz (1500 rpm on 60 Hz) drawing 2.4 A at 480 W or 3.18 A at 695 W respectively, with a 10 µF 400 V capacitor and a starting current of 5.92 A.

Highlights

  • Operates on 230 V AC single-phase power
  • Delivers up to 35000 m³/h airflow
  • Runs at 1370 rpm on 50 Hz supply
  • Withstands ambient temperatures from -40 °C to 60 °C
  • Backward-curved impeller enables compact scroll-free design

Questions about this item

How can I confirm the fan is running correctly after installation?

Measure the motor speed; it should reach 1370 rpm at 50 Hz or 1500 rpm at 60 Hz, and the current draw should be near 2.4 A at 50 Hz or 3.18 A at 60 Hz.

What components are included and what must I source separately?

The fan unit and a 10 µF, 400 V capacitor are supplied; you must provide a 230 V AC single-phase supply and any mounting hardware or ducting required for your enclosure.

Which operating frequency should I select for my 230 V supply?

Choose 50 Hz for 480 W power consumption and 1370 rpm speed, or 60 Hz for 695 W and 1500 rpm; both use the same 10 µF capacitor and 230 V nominal voltage.
