Frequently Asked Questions
What is NMB-MAT 06025VA-12N-CL?
NMB-MAT 06025VA-12N-CL is a 12 VDC axial cooling fan from the NMB 06025VA family. Multiple product listings identify a 60 × 60 × 25 mm frame, 0.35 A current rating and three-wire connection. It is suitable for evaluation in compatible electronic and industrial ventilation systems.
What is the rated voltage of 06025VA-12N-CL?
Commercial references consistently specify a nominal 12 VDC supply. The publicly available NMB 06025VA series datasheet describes operating voltage ranges for standard -AA configurations, but does not establish a separate range for the -CL model. Confirm the actual fan's permitted supply range before operation.
What are the dimensions of 06025VA-12N-CL?
The fan measures 60 mm wide, 60 mm high and 25 mm deep according to multiple model-specific suppliers. The standard 06025VA manufacturer drawing shows approximately 50 mm mounting hole center spacing, but the supplied -CL assembly and any customized housing should be checked for the exact mounting arrangement.
What is the current rating and electrical power?
Multiple suppliers specify 0.35 A at 12 VDC for 06025VA-12N-CL. Multiplying these values produces 4.2 W of nominal electrical input. This figure is consistent across the reviewed commercial listings. Actual electrical consumption should be checked if the equipment has strict power limits.
What is the fan speed of 06025VA-12N-CL?
One independent supplier lists 6300 RPM. However, an exact-model NMB datasheet confirming that speed has not been located. The manufacturer's 06025VA-12N-AA standard version is rated at 7000 RPM, but that value should not be assigned to the -CL model because the two configurations have different reported current ratings.
What are the airflow and maximum static pressure ratings?
An independent supplier reports 33.5 CFM maximum airflow and 0.39 inches of water static pressure, approximately 97 Pa, for the -CL model. These values have not been confirmed against an NMB -CL performance curve. The standard -AA model has separate published figures and should not be used as a substitute for exact -CL specifications.
What is the noise level of 06025VA-12N-CL?
A commercial supplier reports a noise level of 44 dB(A) for the -CL fan. An independent manufacturer measurement for this exact assembly was not located. Actual equipment noise also depends on the enclosure, fan mounting and airflow resistance.
Does 06025VA-12N-CL have three wires?
Yes. Multiple suppliers identify the -CL as a three-wire cooling fan, and some list a three-pin connector. The third conductor may be associated with an alarm or speed-monitoring function, but the exact electrical behavior requires verification against the fan's actual wiring specification.
Does 06025VA-12N-CL have a tachometer or locked-rotor alarm output?
Suppliers provide differing descriptions of the additional wire, including tachometer and alarm functionality. A manufacturer-approved pinout for the complete -CL configuration has not been independently confirmed. Do not connect the third conductor to a control circuit based only on the wire count or supplier description.
Is 06025VA-12N-CL waterproof?
Several suppliers market this model as a waterproof or sealed cooling fan. However, an exact IP protection rating for the -CL assembly was not independently verified. The manufacturer states that environmentally protected and oil-resistant versions can be customized within the broader 06025VA series. Applications requiring a particular IP rating should use documentation for the exact supplied fan.
What is the difference between 06025VA-12N-CL and 06025VA-12N-AA?
Both are associated with NMB's 06025VA family and nominal 12 VDC, 60 × 60 × 25 mm fan format. Commercial listings consistently give 0.35 A for the -CL, while the manufacturer specifies 0.26 A, 7000 RPM, 27.9 CFM and 144.9 Pa for the standard -AA model. The -CL also appears in three-wire configurations. The electrical and performance differences mean the two suffixes should not be assumed interchangeable.
What should be checked before ordering 06025VA-12N-CL?
Verify the complete model 06025VA-12N-CL and any assembly marking, nominal 12 VDC voltage, 0.35 A current rating, 60 × 60 × 25 mm frame dimensions, mounting hole positions, three-wire arrangement, connector shape and pinout, third-wire monitoring function, airflow direction and existing equipment compatibility. For applications requiring specific RPM, airflow, static pressure, noise level, bearing-life rating or environmental protection, obtain exact-model specifications rather than applying the standard 06025VA-12N-AA catalog values.
