SKU CH-56HM-B4SQ2 MPN S2D250-BI02-01Motor

An axial fan with a 250 mm blade diameter, 100 W motor, 400 V supply and 2500 rpm speed for industrial cooling

  • High airflow for demanding cooling with 250 mm blade diameter
  • Strong 100 W motor power drives reliable performance
  • Wide voltage range 230/400 V suits varied installations
  • High speed 2500 rpm delivers effective air movement
  • Axial fan design fits standard case mounting points

Industrial-grade axial fan

The S2D250-BI02-01Motor is a 250mm outer-rotor axial fan built for continuous airflow in industrial and commercial equipment. It operates at 400V with a 100W motor rated for 2500 rpm, making it suitable for drive cooling, medical devices, rail vehicles and similar demanding environments. Custom processing is available for specialised integration needs.

Suited for fixed-installation cooling

This unit fits engineers specifying original-equipment replacement fans for 400V three-phase systems where 250mm blade diameter and 2500 rpm are required. It is not intended for desktop PC chassis, low-voltage builds or any application needing PWM speed control or standard 12V/24V connectors. Buyers needing smaller diameters, different voltages or consumer-style mounting should look elsewhere.

Sustained-operation characteristics

Designed for continuous duty, the motor draws 0.2A at full load and maintains rated speed under prolonged thermal stress typical of industrial cleaning, new-energy vehicle systems and supermarket refrigeration. The outer-rotor construction provides stable airflow without the vibration spikes seen in short-burst consumer fans. No acoustic or bearing-life figures are published for this model.

Questions about this item

Does the 400 V AC input require a dedicated industrial power supply rather than a standard PC PSU?

Yes, the fan runs on 400 V AC at 0.2 A, so it needs an industrial-grade supply, not a typical ATX unit.

Will the 2500 rpm axial airflow interfere with slower chassis fans if mounted in the same enclosure?

The 2500 rpm outer-rotor design moves significantly more air than typical case fans; plan ducting or speed control to avoid turbulence.

How can I confirm the motor is drawing the rated 100 W after installation?

Measure input current at the supply — 0.2 A at 400 V AC indicates the motor is operating at its rated 100 W.
