Frequently Asked Questions
What is NMB-MAT 3110KL-04W-B60?
NMB-MAT 3110KL-04W-B60 is a 12 VDC brushless axial cooling fan from the NMB Technologies 3110KL series. Manufacturer-documented full-suffix variants feature an 80 × 80 × 25 mm frame, 3400 RPM nominal speed, 40.2 CFM maximum airflow and 0.26 A rated current.
What is the rated voltage of 3110KL-04W-B60?
The nominal rated voltage is 12 VDC. NMB specifies an operating voltage range of 6.0–13.0 VDC for the documented B60 variants. Check the fan label and the connected equipment's power supply requirements before installation.
What are the dimensions of 3110KL-04W-B60?
The fan has a nominal frame width of 80 mm, height of 80 mm and depth of 25 mm. This is commonly referred to as an 8025 cooling fan. The physical mounting frame varies by complete suffix, so installation compatibility also depends on the rib or flange design, mounting holes and available clearance.
What are the rated current and power consumption?
The manufacturer specifies 0.26 A rated current and approximately 3.1 W input power. The legacy series performance table lists 3.12 W, consistent with multiplying 12 VDC by 0.26 A. These values are manufacturer-documented for the B60 performance class.
What are the fan speed and maximum airflow specifications?
The nominal fan speed is 3400 RPM and the maximum airflow is 40.2 CFM, equivalent to approximately 1.14 m³/min. These represent manufacturer performance ratings under defined conditions. The actual airflow delivered through equipment will depend on the ventilation system's resistance.
What is the maximum static pressure of 3110KL-04W-B60?
NMB specifies a maximum static pressure of 40.2 Pa, approximately 0.16 inches of water. Maximum static pressure and maximum airflow describe different points on the fan's performance curve; both maximum values should not be assumed to occur simultaneously.
What bearing type does 3110KL-04W-B60 use?
The documented B60 versions use ball bearings. NMB specifies an L10 expected life of 50,000 hours at 25°C. Actual service life depends on temperature, airflow conditions, operating duration and equipment installation.
What is the noise level of 3110KL-04W-B60?
The manufacturer lists a noise level of 35 dB for the documented B60 variants. Actual acoustic performance in an installed enclosure may vary with mounting arrangement, nearby components, airflow resistance and cabinet resonance.
Does 3110KL-04W-B60 have a tachometer or locked-rotor output?
The documented -B00, -D00, -E00, -G00 and -P00 versions are standard two-wire fans. Their manufacturer specifications do not identify a separate tachometer or locked-rotor signal output. If the equipment requires fan speed feedback or a fan alarm signal, confirm a suitable configuration separately.
What is the difference between 3110KL-04W-B60-B00 and 3110KL-04W-B60-E00?
Both have the same manufacturer-listed nominal voltage, current, fan speed, airflow, static pressure and basic frame dimensions. The -B00 version uses a rib-type mounting frame, while the -E00 version uses a flange-type frame. Their manufacturer-listed newer part numbers also differ: 08025SA-12N-AA-D0 for -B00 and 08025SA-12P-EA-D0 for -E00.
Is NMB-MAT 3110KL-04W-B60 discontinued, and what is its replacement?
NMB identifies the documented legacy B60 full-suffix versions as end-of-life products. The manufacturer lists 08025SA-12N-AA-D0 for -B00, 08025SA-12N-EA-D0 for -D00 and -P00, 08025SA-12P-EA-D0 for -E00, and 08025SA-12N-AA-D0 for -G00. These are manufacturer-recommended successor references rather than performance-identical substitutes. For example, the newer 08025SA-12N-AA-D0 is listed at 0.14 A, 3100 RPM and 41.3 CFM, while 08025SA-12P-EA-D0 is listed at 0.24 A, 3500 RPM and 46.96 CFM. The -G00 successor also requires special mounting review because the legacy page specifies a flange frame while the listed successor uses a rib frame.
What should be checked before ordering 3110KL-04W-B60?
Confirm the exact model 3110KL-04W-B60 and complete -B00, -D00, -E00, -G00 or -P00 suffix, nominal 12 VDC supply, 6.0–13.0 VDC operating range, 0.26 A current rating, 3.1 W input power, 80 × 80 × 25 mm frame, 3400 RPM nominal speed, 40.2 CFM maximum airflow, 40.2 Pa maximum static pressure, ball bearing construction, two-wire connection, mounting design, lead termination, airflow direction and equipment compatibility. When evaluating a newer 08025SA model, compare the complete mechanical, electrical, thermal and acoustic specifications rather than relying solely on the manufacturer cross-reference.
