NMB DC Axial fan part number breakdown


#1

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
M - Series
L - Brushless DC Type
04 - 12 Volt input
W - Wire Leads
B - Ball Bearing
1 - Low Speed
0 - Standard Type
B - Standard Model Rib Type
00 - Standard

See below for full breakdown of each section. You can also use this model to help build a part number to your exact specifications, however not all combinations are always available.
