SKU CH-9R17-PMXWP MPN 4715KL-05W-B30Brand

A 24 V case fan delivering 120 CFM at 3300 RPM with a 47 dBA noise rating and double ball bearing

  • 24 V DC operation for industrial power compatibility
  • 3300 RPM double ball bearing ensures long service life
  • 120 CFM airflow delivers strong cooling performance
  • 47 dBA noise level balances output with acoustic comfort
  • PBT frame with 30 % glass fibre meets VO flame retardant standard

24 V double-ball case fan

The NMB-MAT 4715KL-05W-B30 is a 120 mm square frame fan with a 38 mm depth, rated for 24 V DC at 0.40 A and 3300 RPM. It delivers 120 CFM airflow at 47 dBA and uses high-precision double ball bearings in a PBT glass-fibre frame rated VO for flame retardancy. The operating range spans -20 °C to +70 °C with storage down to -40 °C and up to +80 °C.

Suitable for industrial and embedded cooling

This fan suits engineers integrating 24 V cooling into medical devices, rail vehicles, industrial drives, EV systems or telecom equipment where the voltage rail and 38 mm thickness match the chassis design. It is not for builders who need a 12 V fan for standard desktop motherboards, nor for slim enclosures that cannot accommodate a 38 mm deep frame.

24 V 0.40 A power requirement

The single specification that decides fit is the 24 V 0.40 A input; the host system must supply a 24 V rail within ±15 % tolerance and at least 0.40 A per fan, otherwise the unit will not start or will run outside its rated performance envelope.

Questions about this item

What are the mounting hole dimensions for the 120 mm square frame?

The frame is 120 mm by 120 mm with a 38 mm thickness. Standard 120 mm case fan mounting holes align with this footprint.

How do I connect the 24 V power leads correctly?

Connect the red wire to positive 24 V DC and the black wire to ground. The fan draws 0.4 A and tolerates a 15 % voltage range.

When should the double ball bearings be inspected or replaced?

The high precision double ball bearings are rated for continuous operation from -20 °C to +70 °C. Inspect if noise rises above 47 dBA or airflow drops below 120 CFM.
