Frequently Asked Questions
What is NMB-MAT 3106KL-05W-B59?
NMB-MAT 3106KL-05W-B59 is a 24 VDC brushless axial cooling fan from the NMB Technologies 3106KL series. Manufacturer-documented full-suffix versions feature an 80 × 80 × 15 mm frame, 3000 RPM nominal speed and 32.8 CFM maximum airflow.
What voltage does 3106KL-05W-B59 require?
The nominal rated voltage is 24 VDC. NMB specifies an operating voltage range of 10-27.6 VDC for the documented -B00 and -B50 versions. Confirm the voltage requirements on the complete fan label before installation.
What are the dimensions of 3106KL-05W-B59?
The fan measures 80 mm wide, 80 mm high and 15 mm deep. It is commonly described as an 8015 axial cooling fan. Mounting holes, frame design and available cable clearance should also be verified.
What is the rated current of 3106KL-05W-B59?
The manufacturer specifies 0.12 A for the documented 3106KL-05W-B59-B00 and 3106KL-05W-B59-B50 variants, with approximately 2.9 W input power. Some commercial listings for the shortened model designation show 0.16 A; the complete suffix and actual fan label should take precedence.
What are the fan speed and maximum airflow?
NMB lists a nominal speed of 3000 RPM and maximum airflow of 32.8 CFM, approximately 0.93 m³/min. The maximum static pressure is 30 Pa, equivalent to approximately 0.12 inches of water.
What bearing type does 3106KL-05W-B59 use?
The manufacturer-documented -B00 and -B50 variants use ball bearings. NMB specifies an L10 life expectancy of 70,000 hours at 25°C. Actual service life depends on temperature, ventilation restrictions and installation conditions.
Does 3106KL-05W-B59 have three wires?
The documented -B00 and -B50 variants have three-wire leads. In addition to the power conductors, the third wire provides the version-specific monitoring signal. Verify polarity, conductor identification and connector configuration before connecting the fan.
What is the difference between 3106KL-05W-B59-B00 and 3106KL-05W-B59-B50?
Both documented versions share the same 24 VDC nominal rating, 0.12 A rated current, 3000 RPM speed, 32.8 CFM maximum airflow and 80 × 80 × 15 mm dimensions. The -B00 version provides locked-rotor detection, while the -B50 version provides a tachometer output.
What is the difference between a locked-rotor output and a tachometer output?
A locked-rotor output signals a stopped or locked fan condition according to the manufacturer-defined output behavior. A tachometer output supplies pulses related to fan rotation for speed monitoring. They have different electrical functions and cannot be assumed interchangeable.
What is the noise level of 3106KL-05W-B59?
The manufacturer specifies 34 dB for the documented B59 variants under their specified testing conditions. Noise in an installed machine may differ due to enclosure structure, airflow resistance and surrounding equipment.
Is NMB-MAT 3106KL-05W-B59 discontinued?
NMB lists the full-suffix 3106KL-05W-B59-B00 and 3106KL-05W-B59-B50 versions as end-of-life products. The manufacturer recommends 08015SS-24N-AL-00 for the locked-rotor version and 08015SS-24N-AT-00 for the tachometer version. These replacements use sleeve bearings and have different performance and lifetime specifications, so application suitability must be verified.
What should be checked before ordering 3106KL-05W-B59?
Verify the complete fan model 3106KL-05W-B59 and any -B00 or -B50 suffix, 24 VDC nominal supply, 0.12 A documented current rating, 80 × 80 × 15 mm dimensions, mounting hole positions, 3000 RPM speed, 32.8 CFM maximum airflow, ball bearing construction, wire leads, connector details, locked-rotor or tachometer monitoring requirements and the specifications of any proposed replacement. Confirm compatibility with the existing equipment before installation.
