SKU CH-E857-NFWK7 MPN 4715KL-07W-B39

120 mm axial fan delivers 108 CFM airflow at 2950 RPM from a 48 V supply

  • High airflow for dense chassis with 108 CFM delivery
  • 48 V operation suits industrial and server power rails
  • Low 0.21 A draw keeps power budgets tight
  • 2950 RPM speed enables targeted spot cooling
  • 50000 hour rated life reduces replacement cycles

Industrial 48 V DC case fan

This 120 mm × 120 mm × 38 mm axial fan from Japan NMB-MAT runs on 48 V DC and draws 0.21 A for 10.08 W. It spins at 2950 RPM and delivers 108 CFM (3.07 m³/min) at 68.2 Pa static pressure with a noise level of 42.5 dBA. The unit is rated for 50,000 hours at -20 °C to 75 °C and weighs 260 g.

Suited for industrial enclosures and OEM cooling

The fan fits medical, rail, EV, telecom and industrial equipment that supply a 48 V DC rail and need high airflow in a 12038 form factor. It is not for standard PC builders whose motherboards only provide 12 V fan headers, nor for silent desktop users who need lower noise than 42.5 dBA.

48 V DC operating voltage

The single specification that decides fit is the 48 V DC input; the fan requires a 48 V power source and will not operate on the 12 V headers found on consumer motherboards.

Questions about this item

How can I confirm the fan is running at the rated 2950 RPM after installation?

The model supports speed measurement via its three-wire connection; monitor the RPM reading in BIOS or fan-control software and verify it reaches 2950 RPM.

What comes with the fan and what must I source separately?

The unit is supplied as the 120 × 120 × 38 mm fan only; a 48 V power source, mounting screws and any PWM or voltage-control cable are not included.

Which voltage version should I choose for a 48 V DC system?

This model is the 48 V variant (0.21 A, 10.08 W); select it only if your system provides a 48 V DC rail.
