The NMB-MAT 3615KL-05W-B50 belongs to the 3615KL series of DC axial cooling fans. Its 92 mm square frame and approximately 38 mm depth support installation in compatible industrial electronics, power conversion equipment and ventilation assemblies that require a relatively deep axial fan frame.
The manufacturer-documented 3615KL-05W-B50-P00 operates at a nominal 24 VDC, with a specified operating voltage range of 12–25.2 VDC. Its rated current is 0.24 A and its electrical input power is approximately 5.76 W, supporting equipment cooling circuits designed for these operating requirements.
NMB specifies a nominal fan speed of 4000 RPM and maximum free-air flow of 76.2 CFM, equivalent to approximately 2.16 m³/min. These characteristics make the fan suitable for cooling applications where the equipment's ventilation design requires the documented airflow capacity.
The documented B50 variant has a maximum static pressure rating of 89.2 Pa, approximately 0.36 inches of water. This represents the fan's pressure capability at its defined measurement point. The actual operating airflow depends on enclosure vents, filters, heatsinks and other flow resistance.
The -P00 version uses ball bearings with an L10 expected life of 100,000 hours at 25°C. The manufacturer datasheet also describes automatic restart and reverse-polarity protection. These features support fan operation under the specified electrical and environmental conditions.
The manufacturer's product page identifies 09238RA-24N-EAD-0 as the replacement for the discontinued 3615KL-05W-B50-P00. However, the replacement has different current, rotational speed and airflow ratings, so it should not be regarded as a direct electrical and thermal equivalent without reviewing the installation requirements.
We support online purchase inquiries for the NMB-MAT 3615KL-05W-B50 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 and transportation arrangements after reviewing your requirements. The documented 3615KL-05W-B50-P00 is an end-of-life product, so the complete model suffix, connection configuration and any proposed replacement should be confirmed before ordering.
What is NMB-MAT 3615KL-05W-B50?
NMB-MAT 3615KL-05W-B50 identifies a 24 VDC axial cooling fan from the NMB Technologies 3615KL series. The manufacturer-documented full model 3615KL-05W-B50-P00 has a 92 × 92 × 38 mm nominal frame, 4000 RPM rotational speed and 76.2 CFM maximum airflow.
What is the rated voltage of 3615KL-05W-B50?
The nominal voltage is 24 VDC. NMB specifies an operating voltage range of 12–25.2 VDC for the documented -P00 version. Before installing the fan, verify the exact assembly label and the power supply operating conditions.
What are the dimensions of 3615KL-05W-B50?
The nominal fan frame measures 92 mm wide, 92 mm high and 38 mm deep. The detailed mechanical drawing specifies a depth of 38.4 ±0.5 mm. The mounting hole center spacing is approximately 82.5 mm, with mounting holes of 4.3 mm diameter.
What is the rated current and power consumption?
The manufacturer lists 0.24 A rated current and approximately 5.8 W input power for 3615KL-05W-B50-P00. A detailed datasheet specifies 5.76 W. These are consistent nominal electrical values for the documented version.
What are the fan speed and maximum airflow specifications?
NMB specifies a nominal speed of 4000 RPM and maximum airflow of 76.2 CFM, approximately 2.16 m³/min. These ratings represent performance under the manufacturer's measurement conditions. Installed airflow will depend on the resistance of the equipment cooling path.
What is the maximum static pressure of 3615KL-05W-B50?
The documented maximum static pressure is 89.2 Pa, approximately 0.36 inches of water. This figure should be evaluated together with the fan's pressure-flow performance curve when assessing a particular enclosure or heatsink cooling system.
What bearing type does 3615KL-05W-B50 use?
The documented -P00 version uses ball bearings. Its manufacturer-listed L10 expected life is 100,000 hours at 25°C. This is a statistical bearing-life measure under specified conditions rather than a guaranteed operating duration for each fan.
What is the operating temperature range?
The manufacturer datasheet identifies -10°C to +60°C as the operating ambient temperature range for the B50 performance class. The published storage range is -40°C to +70°C under non-condensing conditions. The installed equipment should be designed to remain within the applicable operating limits.
Does 3615KL-05W-B50 have two wires or a tachometer output?
There is a documentation discrepancy for the complete 3615KL-05W-B50-P00 model. NMB's product page lists a tachometer output, while DigiKey identifies the same catalog number as a two-wire fan without a speed-sensor feature. The electrical connection and monitoring functionality should therefore be verified directly from the supplied fan label, actual wire count and manufacturer wiring documentation rather than assuming the presence of a tachometer output.
What is the difference between 3615KL-05W-B50 and 3610KL-05W-B50?
The 3615KL series uses a 92 × 92 × 38 mm nominal frame, while the 3610KL series uses a 92 × 92 × 25 mm frame. The 3615KL-05W-B50-P00 is rated at 4000 RPM, 76.2 CFM and 0.24 A, whereas the documented 3610KL-05W-B50-B00 has a 3200 RPM, 54.7 CFM and 0.16 A rating. Their dimensions and electrical characteristics differ, so they are not automatically interchangeable.
Is NMB-MAT 3615KL-05W-B50 discontinued?
NMB identifies the complete 3615KL-05W-B50-P00 as an end-of-life product and lists 09238RA-24N-EAD-0 as its replacement. The replacement has a higher rated current of 0.71 A, 6200 RPM speed and 141.2 CFM airflow, compared with 0.24 A, 4000 RPM and 76.2 CFM for the legacy fan. Confirm electrical, noise, cooling and mechanical compatibility before substitution.
What should be checked before ordering 3615KL-05W-B50?
Verify the complete model number 3615KL-05W-B50 and any additional suffix such as -P00, 24 VDC nominal supply, 0.24 A rated current, approximately 5.8 W power rating, 92 × 92 × 38 mm frame dimensions, 4000 RPM nominal speed, 76.2 CFM maximum airflow, 89.2 Pa maximum static pressure, ball bearing construction, mounting hole positions, connector and wire arrangement, fan monitoring requirements, airflow direction and existing equipment compatibility. If replacing a discontinued fan, review the replacement's full specifications rather than relying on a manufacturer cross-reference alone.
