The NMB-MAT 1608VL-05W-B59 belongs to the 1608VL series of compact DC axial cooling fans. Its nominal 40 mm square frame and 20 mm thickness provide forced-air ventilation for compatible industrial electronics, compact control assemblies and equipment enclosures where installation space is limited.
The manufacturer-documented 1608VL-05W-B59 variants operate from a nominal 24 VDC supply, with a specified operating voltage range of 14–26.4 VDC. The rated current is 0.07 A and input power is approximately 1.7 W, supporting compatible low-voltage electronic cooling systems.
NMB specifies a nominal rotational speed of 8500 RPM and maximum airflow of 10.2 CFM, equivalent to approximately 0.29 m³/min. These characteristics support airflow through compact equipment ventilation paths and electronic component cooling arrangements.
The documented B59 variants deliver a maximum static pressure of 76.6 Pa, approximately 0.31 inches of water. The actual airflow obtained in an enclosure depends on the resistance of ventilation openings, circuit boards, heatsinks and filters.
The manufacturer-documented versions use ball bearings with an L10 life expectancy of 100,000 hours at 25°C. Distributor-referenced series documentation also provides a 40,000-hour life reference at 60°C. These figures describe specified statistical operating conditions rather than a guaranteed individual fan lifespan.
The complete part-number suffix determines the fan monitoring function. The 1608VL-05W-B59-B00 provides a locked-rotor output, while 1608VL-05W-B59-B50 provides a tachometer output. Both use a documented rib-type frame and three-wire connection. The monitoring signal must match the receiving equipment's electrical requirements.
We support online purchase inquiries for the NMB-MAT 1608VL-05W-B59 DC Axial Fan. If you need to make bulk purchases or inquire about related products, please contact our team with the required quantity, complete model number and equipment specifications. We can provide quotation information and discuss delivery dates and transportation methods after reviewing your requirements. For replacement applications, please confirm whether your existing fan is the 1608VL-05W-B59-B00 locked-rotor version or the 1608VL-05W-B59-B50 tachometer version. The manufacturer lists corresponding newer part numbers 04020VA-24N-AL-00 and 04020VA-24N-AT-00, respectively. Verify the complete mounting and electrical configuration before substitution.
What is NMB-MAT 1608VL-05W-B59?
NMB-MAT 1608VL-05W-B59 is a 24 VDC brushless axial cooling fan from the NMB Technologies 1608VL series. Manufacturer-documented full-suffix models include 1608VL-05W-B59-B00 and 1608VL-05W-B59-B50, both featuring a 40 × 40 × 20 mm nominal frame, 8500 RPM speed and 10.2 CFM maximum airflow.
What is the rated voltage of 1608VL-05W-B59?
The nominal rated voltage is 24 VDC. NMB specifies an operating voltage range of 14–26.4 VDC for the documented -B00 and -B50 versions. The fan should be connected to a compatible DC supply, with polarity and wiring verified before installation.
What are the dimensions of 1608VL-05W-B59?
The manufacturer's nominal dimensions are 40 mm wide, 40 mm high and 20 mm deep. DigiKey lists the outside frame size as approximately 40.1 × 40.1 mm with a 20 mm depth. The mounting hole arrangement and connector clearance should also be checked against the existing equipment.
What is the rated current and power consumption?
The manufacturer specifies 0.07 A rated current and approximately 1.7 W input power for the documented B59 variants. Distributor specifications list 1.68 W, consistent with 24 VDC multiplied by 0.07 A. Actual operating current may vary with supply voltage and equipment conditions.
What are the fan speed and maximum airflow specifications?
NMB specifies a nominal fan speed of 8500 RPM and maximum airflow of 10.2 CFM, equivalent to approximately 0.29 m³/min. The actual airflow through a particular device depends on enclosure airflow resistance and installation conditions.
What is the maximum static pressure of 1608VL-05W-B59?
The manufacturer lists a maximum static pressure of 76.6 Pa, equivalent to approximately 0.31 inches of water. This is a maximum pressure capability and should not be interpreted as the pressure available at the maximum free-air flow point.
What bearing type does 1608VL-05W-B59 use?
The manufacturer-documented -B00 and -B50 versions use ball bearings. NMB lists an L10 life expectancy of 100,000 hours at 25°C. The actual service life of an individual fan depends on operating temperature, installation conditions and other environmental factors.
Does 1608VL-05W-B59 have three wires?
Yes. The documented -B00 and -B50 variants use three-wire leads. Two conductors provide DC power and the additional conductor carries the version-specific monitoring output. The connector type, lead colors and third-wire electrical behavior should be checked against the exact assembly.
What is the difference between 1608VL-05W-B59-B00 and 1608VL-05W-B59-B50?
Both documented versions share the same nominal 24 VDC rating, 0.07 A current, 8500 RPM fan speed, 10.2 CFM maximum airflow, 76.6 Pa maximum static pressure and 40 × 40 × 20 mm frame. The -B00 model provides a locked-rotor output, while the -B50 model provides a tachometer signal. These outputs are intended for different monitoring functions.
What is the difference between 1608VL-05W-B59 and 1608KL-05W-B59?
The documented 1608VL B59 versions provide 10.2 CFM airflow, 76.6 Pa maximum static pressure, 8500 RPM speed and 0.07 A current. The documented 1608KL B59 versions have the same nominal 24 VDC voltage and 40 × 40 × 20 mm frame, but are rated at 9.5 CFM airflow, 69.4 Pa maximum static pressure and 0.08 A current. These models have different cooling and electrical characteristics and should not be assumed interchangeable.
Is NMB-MAT 1608VL-05W-B59 discontinued?
NMB identifies the documented -B00 and -B50 legacy models as not recommended for new designs and lists a part-number change. DigiKey lists both legacy models as obsolete. The manufacturer identifies 04020VA-24N-AL-00 as the newer part number for -B00 and 04020VA-24N-AT-00 for -B50. The manufacturer's replacement records retain the corresponding locked-rotor and tachometer monitoring functions.
What should be checked before ordering 1608VL-05W-B59?
Confirm the complete model number 1608VL-05W-B59 and any additional -B00 or -B50 suffix, nominal 24 VDC supply, 0.07 A rated current, 40 × 40 × 20 mm dimensions, 8500 RPM fan speed, 10.2 CFM airflow, 76.6 Pa maximum static pressure, ball bearing construction, rib-type mounting, three-wire connection, connector details, airflow direction and locked-rotor or tachometer monitoring requirements. If selecting the newer 04020VA series, verify electrical, mechanical and signal compatibility with the installed equipment before replacement.
