Compact 80 mm blower for 24 V systems

The NMB-MAT 3110KL-05W-B50 is an 80 × 80 × 25 mm DC blower rated for 24 V operation with a working range of 10.0 V to 27.6 V. It suits servers, industrial enclosures and medical or rail equipment that need a thin, high-pressure airflow path.

Original factory build with two-wire lead

Supplied as a brand-new OEM unit, the blower weighs 95 g and uses a simple two-wire power connection drawing 0.12 A typical and 0.15 A maximum. The compact frame fits standard 8025 mounting holes, so installation is a direct swap in existing 80 mm cut-outs without adapters.

3250 RPM delivering 38.8 CFM at 34 dBA

At full speed the fan moves 38.8 CFM against 38.8 Pa static pressure while consuming 2.88 W. The measured acoustic output is 34 dBA, making it audible but not intrusive in rack or cabinet environments where directed cooling is required.

Questions about this item

Does the 24 V DC input limit speed to 3250 RPM in practice?

The fan runs at 3250 RPM when supplied with 24 V DC; the working range is 10.0 V to 27.6 V so speed will vary with voltage.

Will the 80 mm by 25 mm frame fit a standard 8025 mounting pattern?

The 80 mm square frame with 25 mm thickness matches the 8025 form factor used in many server and industrial chassis.

How do I wire the two leads without reversing polarity?

Connect the positive lead to 24 V DC and the negative lead to ground; reversing them will prevent the blower from starting.
