The NMB-MAT 4710KL-04W-B59 is a DC axial cooling fan from the 4710KL series. Its 119 mm square frame and 25 mm depth support forced-air ventilation in compatible electronic equipment, power supply assemblies and industrial enclosures. It belongs to the commonly used 120 mm cooling fan size class.
Manufacturer-documented B59 variants operate at a nominal 12 VDC, with a specified operating voltage range of 6.0–13.0 VDC. Their rated current is 0.55 A and input power is 6.6 W. The equipment power supply should be capable of supporting these electrical requirements.
NMB specifies 2800 RPM nominal speed and 114.7 CFM maximum airflow, equivalent to 3.25 m³/min. These characteristics support forced-air cooling applications where a substantial volume of air must move through a compatible ventilation path.
The documented legacy B59 configurations have a maximum static pressure rating of 50.5 Pa, approximately 0.20 inches of water. Actual airflow depends on resistance from heatsinks, ventilation grilles, filters and equipment enclosure design. Maximum pressure and maximum airflow are separate performance points.
The manufacturer identifies ball bearing construction for the documented B59 configurations. The full part-number suffix determines whether the fan provides a locked-rotor output or a tachometer output. A 100,000-hour L10 life reference at 25°C is expressly associated with the legacy -B00 and -E00 versions in the manufacturer's product records.
NMB identifies the 11925SA-12Q series as the successor family for the documented legacy B59 variants. Separate replacement models retain the corresponding monitoring and mounting configurations. Their operating characteristics differ from the legacy fan, so electrical, mechanical and thermal compatibility should be checked before substitution.
We support online purchase inquiries for the NMB-MAT 4710KL-04W-B59 DC Axial Fan. If you need to make bulk purchases or inquire about related cooling products, please contact our team with the required quantity, complete model number and equipment specifications. Please confirm whether your required version is -B00, -B50, -E00 or -E50, as these suffixes determine the mounting arrangement and fan monitoring output. We can provide quotation information and discuss applicable delivery and transportation arrangements after reviewing your request. The documented legacy models are listed by the manufacturer as end-of-life products. If you are considering the newer 11925SA-12Q series, please verify the differences in current, speed, airflow, static pressure, noise and wiring requirements before ordering.
What is NMB-MAT 4710KL-04W-B59?
NMB-MAT 4710KL-04W-B59 is a 12 VDC brushless axial cooling fan from the NMB Technologies 4710KL series. The documented legacy variants feature a nominal 119 × 119 × 25 mm frame, 2800 RPM rotational speed, 114.7 CFM maximum airflow and 0.55 A rated current.
What is the rated voltage of 4710KL-04W-B59?
The nominal voltage is 12 VDC. NMB specifies an operating voltage range of 6.0–13.0 VDC for the documented -B00, -B50, -E00 and -E50 configurations. Confirm the fan label and equipment supply requirements before installation.
What are the dimensions of 4710KL-04W-B59?
The manufacturer specifies a frame width of 119 mm, height of 119 mm and depth of 25 mm. The fan belongs to the 120 mm size class. The physical mounting design may be rib or flange type depending on the full model suffix, so nominal frame dimensions alone are not sufficient to establish interchangeability.
What are the rated current and power consumption?
NMB specifies a rated current of 0.55 A and input power of 6.6 W at 12 VDC for the documented legacy B59 configurations. The electrical rating should be checked against the existing equipment's fan power circuit.
What are the fan speed and maximum airflow specifications?
The manufacturer lists 2800 RPM nominal speed and 114.7 CFM maximum airflow, equivalent to 3.25 m³/min. Actual airflow through an installed equipment enclosure depends on the system's airflow resistance and operating conditions.
What is the maximum static pressure of 4710KL-04W-B59?
The maximum static pressure is 50.5 Pa, equivalent to approximately 0.20 inches of water. This rating represents the manufacturer's maximum pressure measurement and does not occur simultaneously with the maximum free-air flow rating.
What is the noise level of 4710KL-04W-B59?
NMB specifies 41.5 dB for the documented legacy B59 versions. Installed noise can vary according to enclosure construction, fan mounting, vibration transmission and airflow restrictions.
What bearing type and life expectancy does the fan have?
The documented legacy B59 variants use ball bearings. NMB publishes a 100,000-hour L10 life reference at 25°C, specifically labeled for the -B00 and -E00 configurations. The manufacturer product records for the tachometer variants reproduce this same reference rather than providing a separately defined life rating. The successor 11925SA-12Q models publish 40,000 hours L10 at 60°C, which uses a different temperature basis and cannot be compared directly with the legacy 25°C figure.
Does 4710KL-04W-B59 have three wires?
The documented -B00, -B50, -E00 and -E50 configurations use three-wire connections. Two wires provide DC power, while the additional wire carries the monitoring signal specified by the complete suffix. Confirm lead colors, connector termination and signal characteristics against the exact equipment connection requirements.
What is the difference between 4710KL-04W-B59-B00, -B50, -E00 and -E50?
All four manufacturer-documented variants share the same nominal 12 VDC voltage, 0.55 A current, 2800 RPM speed, 114.7 CFM maximum airflow, 50.5 Pa maximum static pressure and 119 × 119 × 25 mm frame. The -B00 version uses rib mounting with locked-rotor output; -B50 uses rib mounting with tachometer output; -E00 uses flange mounting with locked-rotor output; and -E50 uses flange mounting with tachometer output. These configurations should not be interchanged without checking the mounting and monitoring requirements.
Is NMB-MAT 4710KL-04W-B59 discontinued, and what are its replacements?
NMB identifies the four documented full-suffix B59 variants as end-of-life products. The manufacturer lists 11925SA-12Q-ALD-0 for -B00, 11925SA-12Q-ATD-0 for -B50, 11925SA-12Q-ELD-0 for -E00 and 11925SA-12Q-ETD-0 for -E50. These successor models preserve the corresponding mounting and monitoring categories, but have different published electrical and cooling performance.
What should be checked before ordering 4710KL-04W-B59?
Confirm the complete model number 4710KL-04W-B59 and additional -B00, -B50, -E00 or -E50 suffix; nominal 12 VDC voltage; 6.0–13.0 VDC operating range; 0.55 A current; 6.6 W input power; 119 × 119 × 25 mm frame; 2800 RPM speed; 114.7 CFM maximum airflow; 50.5 Pa maximum static pressure; ball bearing construction; mounting arrangement; three-wire connection; connector type; and locked-rotor or tachometer monitoring requirements. For a manufacturer-listed 11925SA-12Q replacement, review its separate ratings of 0.47 A, 3100 RPM, 113 CFM, 73 Pa and 44 dB rather than treating it as performance-identical to the legacy fan.
