Frequently Asked Questions
What is NMB-MAT 2410ML-05W-B70?
NMB-MAT 2410ML-05W-B70 is a 24 VDC brushless axial cooling fan from the NMB Technologies 2410ML series. Manufacturer-documented full-suffix versions include 2410ML-05W-B70-B00 and 2410ML-05W-B70-E00, both featuring 60 × 60 × 25 mm dimensions, 6800 RPM speed and 33.1 CFM maximum airflow.
What is the rated voltage of 2410ML-05W-B70?
The nominal rated voltage is 24 VDC. NMB specifies an operating voltage range of 10.0-25.2 VDC for the documented -B00 and -E00 configurations. The fan should be connected to a power source that meets the manufacturer electrical requirements.
What are the dimensions of 2410ML-05W-B70?
The fan measures 60 mm wide, 60 mm high and 25 mm deep. This configuration is commonly described as a 6025 axial cooling fan. The installed mounting arrangement and electrical lead clearance must also be verified before replacement.
What is the rated current and power consumption?
The manufacturer specifies a rated current of 0.19 A and an input power of 4.6 W for the documented -B00 and -E00 variants. Actual operating current can vary with voltage and fan operating conditions, so the complete fan label should be checked.
What are the fan speed and maximum airflow specifications?
NMB lists 6800 RPM nominal speed and a maximum airflow of 33.1 CFM, equivalent to approximately 0.94 m³/min. These specifications are measured under defined conditions and do not represent guaranteed airflow after installation inside equipment.
What is the maximum static pressure of 2410ML-05W-B70?
The documented maximum static pressure is 125 Pa, equivalent to approximately 0.50 inches of water. The operating airflow depends on the intersection of the fan performance curve and the actual resistance of the equipment ventilation path.
What bearing type does 2410ML-05W-B70 use?
The manufacturer-documented B70 variants use ball bearings. NMB specifies an L10 life expectancy of 100,000 hours at 25°C. This is a statistical bearing-life rating rather than a guarantee that every fan will operate for that duration.
Does 2410ML-05W-B70 have two wires?
The documented 2410ML-05W-B70-B00 and 2410ML-05W-B70-E00 versions use standard two-wire electrical connections without a separate tachometer or locked-rotor output. Lead length, connector termination and polarity should be verified against the complete supplied assembly.
What is the difference between 2410ML-05W-B70-B00 and 2410ML-05W-B70-E00?
Both versions share the same documented 24 VDC voltage, 0.19 A current, 6800 RPM speed, 33.1 CFM airflow and 60 × 60 × 25 mm frame dimensions. The difference is the mounting construction: -B00 is a rib-mount version, while -E00 is a flange-mount version. The two configurations should not be interchanged without checking installation compatibility.
What is the difference between 2410ML-05W-B70 and 2410ML-05W-B60?
The B70 versions operate at 6800 RPM with 33.1 CFM maximum airflow, 125 Pa maximum static pressure and 0.19 A rated current. The B60 versions operate at 5300 RPM with 25 CFM airflow, 73 Pa static pressure and 0.13 A current. Both share the 60 × 60 × 25 mm format, but the B70 has a higher-speed, higher-power cooling configuration.
Is NMB-MAT 2410ML-05W-B70 discontinued?
NMB identifies the full-suffix 2410ML-05W-B70-B00 and 2410ML-05W-B70-E00 models as end-of-life products. The manufacturer product pages list 06025SA-24S-AA-D0 and 06025SA-24S-EA-D0 respectively as replacement references. Replacement fans may have different airflow, speed, current and noise ratings, so suitability must be verified before installation.
What should be checked before ordering 2410ML-05W-B70?
Verify the exact model number 2410ML-05W-B70 and any additional -B00 or -E00 suffix, 24 VDC nominal voltage, 0.19 A rated current, 60 × 60 × 25 mm dimensions, 6800 RPM fan speed, 33.1 CFM maximum airflow, 125 Pa maximum static pressure, ball bearing type, two-wire connection, mounting arrangement, airflow direction, connector termination and compatibility with the existing equipment. If replacing a discontinued version, compare the complete electrical and cooling specifications of the proposed replacement rather than relying on the frame dimensions alone.
