NMB DC Axial fan part number breakdown

How do you verify the specifications of your fan based on the manufacturer’s part number?

For this example I will be using the NBM fan part number 2410ML-04W-B10-B00.

This will divide into 11 different sections.
24 - 60 mm fan
10 - 25 mm thickness

B - Ball Bearing
1 - Low Speed
0 - Standard Type
B - Standard Model Rib Type
00 - Standard

For the part number breakdown on The NMB fans, an actual speed is not listed but only a scale. The speed listing is a comparative scale and not an absolute reference. It will vary greatly from series to series. We do list the fan RPM on Our landing page for each fan part number. Here is the Digi key link to an example DC fan from NMB Note under Product Attributes that the RPM of this particular fan is listed.
