Vszerda

Vszerda 4715VL-05W-B70 case fan 24V 1.20A 120x120x38mm 5700 rpm

SKU CH-QWCZ-BECDF MPN 4715VL-05W-B70

24 V DC case fan measuring 120 × 120 × 38 mm, spinning at 5700 rpm and delivering 215.7 CFM airflow via a two-wire connector

  • High airflow of 215.7 CFM moves heat fast
  • 5700 rpm speed delivers strong cooling performance
  • 24 V DC 1.20 A input suits industrial power rails
  • 120 × 120 × 38 mm fits standard mounting points
  • Two-wire connector simplifies installation and replacement

24V inverter cooling fan for industrial chassis

The Vszerda 4715VL-05W-B70 is a DC 24V axial fan built around an NMB-MAT motor. It draws 1.20 A at full speed and spins at 5700 rpm to move 215.7 CFM of air through a 120 x 120 x 38 mm frame. The two-wire connector suits direct wiring to 24 V rails in servers, inverters or telecom enclosures.

Replaces worn 24V 120 mm fans in high-airflow roles

Swap this unit in when an existing 24 V fan of the same 120 x 120 x 38 mm footprint has failed or lost speed. The jump is worthwhile if the original fan ran below 5700 rpm or delivered less than 215.7 CFM, because the higher flow restores design cooling margins without changing the mounting pattern.

Verify 24 V supply and two-wire header before

Confirm your system provides a stable DC 24 V rail rated for at least 1.2 A and that the fan header or terminal block accepts a two-wire plug. The 38 mm thickness needs 38 mm of clear depth behind the 120 mm mounting holes. No PWM or tachometer signal is present, so fan-speed monitoring must be handled externally.

Questions about this item

Will the 120 mm by 120 mm frame with a 38 mm thickness fit my standard 120 mm fan mounting holes?

Yes, the fan measures 120X120X38 mm, matching the common 120 mm square mounting pattern used in most cases and radiators.

How do I connect the 2-wire lead to a 24 V DC power source without reversing polarity?

The fan uses a 2-wire connector; connect the positive lead to 24 V and the negative lead to ground, observing the wire markings to avoid reversed polarity.

When should I plan to replace the fan if it runs continuously at 5700 rpm?

Continuous operation at 5700 rpm will wear the bearings over time; expect to replace the unit when airflow drops noticeably or bearing noise becomes audible.
