The NMB-MAT 4715FS-12T-B50 is an AC axial cooling fan from the 4715FS family. Its manufacturer-documented complete model, 4715FS-12T-B50-D00, is rated for nominal 115 VAC operation at 60Hz. The fan is designed for forced-air ventilation in compatible industrial electronics and equipment enclosures.
The fan features a nominal 119 mm square frame with a 38 mm depth. Its aluminum alloy housing, reinforced plastic impeller and flange-type mounting arrangement provide a defined mechanical format for compatible cooling installations. The NMB series drawing indicates approximately 105 mm mounting-hole spacing and 3.8 mm diameter mounting holes.
For the documented -D00 version at 60Hz, NMB specifies 3100 RPM, 110 CFM maximum airflow and 92.5 Pa maximum static pressure. The published acoustic rating is 45 dB. These performance specifications apply to the legacy 4715FS-12T-B50-D00, and installed airflow will depend on enclosure resistance and ventilation conditions.
The 4715FS family uses a shaded-pole induction motor with impedance protection. The legacy -D00 model is rated at 0.19 A and 14.4 W input power. Unlike similarly sized DC cooling fans, this component requires a compatible AC supply and electrical installation appropriate to the operating voltage.
NMB identifies ball bearings, a 100,000-hour L10 expected life at 25°C and a -10°C to +70°C operating temperature range. The series uses an aluminum alloy frame and UL94V-0 reinforced plastic impeller. The expected-life figure is a statistical reference under defined conditions, not a guarantee for every individual installation.
NMB identifies 11938FB-A1N-EA-00 as the new part number corresponding to legacy 4715FS-12T-B50-D00. However, the current successor webpage publishes 105.5 CFM and 75.9 Pa, while the older product and manufacturer series PDF specify 110 CFM and 92.5 Pa. The complete replacement specification should therefore be checked before substitution in airflow-sensitive equipment.
We support online purchase inquiries for the NMB-MAT 4715FS-12T-B50 AC Axial Fan. For individual units, bulk purchasing requirements or information about related industrial cooling products, please contact our team with the complete model number, required quantity and equipment specifications. The documented 4715FS-12T-B50-D00 is rated for nominal 115 VAC at 60Hz and uses a two-terminal electrical connection. We can provide quotation information and discuss applicable delivery and transportation arrangements after reviewing your request. NMB identifies 11938FB-A1N-EA-00 as the newer part number, but published airflow and static pressure data differ between manufacturer records. Before replacing an existing fan, verify the electrical supply frequency, terminal arrangement, frame dimensions, mounting-hole spacing, rotation and airflow direction, and the thermal performance required by the equipment. Installation should be performed using appropriate electrical safety procedures.
What is NMB-MAT 4715FS-12T-B50?
NMB-MAT 4715FS-12T-B50 is an AC axial cooling fan from the NMB Technologies 4715FS series. The manufacturer-documented complete model is 4715FS-12T-B50-D00. It features a 119 × 119 × 38 mm frame, a 115 VAC nominal supply, 60Hz operating frequency, shaded-pole induction motor and ball bearings.
Is 4715FS-12T-B50 an AC fan or DC fan?
It is an AC axial cooling fan. NMB specifies a nominal 115 VAC supply for the documented -D00 configuration. It must not be connected to 12 VDC, 24 VDC or 48 VDC fan power circuits or replaced with a DC fan simply because the mechanical dimensions appear similar.
Can 4715FS-12T-B50 operate at both 50Hz and 60Hz?
The manufacturer documentation located for 4715FS-12T-B50-D00 specifies 60Hz operation. A corresponding verified 50Hz rating for this complete model was not established. Therefore, the fan should not automatically be treated as a universal 50/60Hz component. If the equipment uses 50Hz power, confirm compatibility and electrical performance through the manufacturer before installation.
What is the rated voltage, starting voltage and current?
NMB specifies 115 VAC nominal voltage, 75 VAC starting voltage and 0.190 A current at 60Hz. The starting-voltage figure is not a recommended continuous operating voltage. Use the specified nominal supply and verify the equipment electrical circuit before connecting the fan.
What are the physical dimensions and mounting specifications?
The nominal fan dimensions are 119 mm wide, 119 mm high and 38 mm deep. The manufacturer series drawing shows approximately 105 × 105 mm mounting-hole center spacing, 3.8 mm mounting holes and an approximately 116.5 mm panel opening. The fan uses a flange-type frame. Check the actual equipment mounting arrangement and clearance before replacement.
What is the input power of 4715FS-12T-B50?
The manufacturer specifies 14.4 W input power for 4715FS-12T-B50-D00 at 115 VAC and 60Hz, with a published tolerance of +10% / -20%. Because the fan has an AC induction motor, multiplying RMS voltage by current does not necessarily provide the real electrical input power. Use the manufacturer-published wattage when assessing the documented load.
What is the fan speed of 4715FS-12T-B50?
The documented nominal fan speed is 3100 RPM at 60Hz. This is the manufacturer's published value for 4715FS-12T-B50-D00. Other 4715FS performance variants, including B30 and B40, operate at different speeds and should not be assigned the B50 rating.
What are the maximum airflow and static pressure ratings?
NMB specifies 110 CFM maximum airflow, equivalent to approximately 3.10 m³/min, and 92.5 Pa maximum static pressure, equivalent to 0.37 inches of water, for the legacy -D00 at 60Hz. Maximum airflow and maximum static pressure represent different operating points on the fan curve and are not achieved simultaneously. Installed airflow depends on the cooling system resistance.
What is the noise level of 4715FS-12T-B50?
The manufacturer specifies a 45 dB noise rating for the documented legacy model at 60Hz. Noise in an installed cabinet may vary with fan guards, ventilation restrictions, mounting vibration, surrounding equipment and enclosure resonance.
What are the bearing type, motor structure and expected life?
The fan uses ball bearings and a shaded-pole induction motor with impedance protection. The manufacturer lists an L10 expected life of 100,000 hours at 25°C, an operating temperature range of -10°C to +70°C, insulation resistance of at least 10 MΩ at 500 VDC and dielectric withstand of 700 VAC for one second. The L10 figure is a statistical life measure under specified conditions and is not a guaranteed service duration.
Does 4715FS-12T-B50 use terminals or lead wires?
The documented 4715FS-12T-B50-D00 is a two-terminal AC fan. NMB's series documentation identifies Faston #110 or equivalent terminals and separately describes lead-wire versions using AWG22 UL3266 / CSA CL1252 wire. A lead-wire assembly should not be assumed to have the same complete part designation as the standard terminal model. The documented two-terminal configuration has no separate tachometer or PWM control conductor.
Is 4715FS-12T-B50 discontinued, and what is its replacement?
NMB identifies the legacy 4715FS-12T-B50-D00 as not recommended for new designs, while DigiKey lists the model as obsolete. NMB's replacement database and the 11938FB series PDF identify 11938FB-A1N-EA-00 as the successor. The legacy model and manufacturer series PDF specify 110 CFM and 92.5 Pa, but the current manufacturer successor webpage lists 105.5 CFM and 75.9 Pa. Because these performance values differ, confirm the complete successor specification before substitution. Check the 115 VAC supply, 60Hz frequency, 0.19 A current, 14.4 W input power, 119 × 119 × 38 mm frame, terminal design, mounting dimensions, rotation, airflow direction and required cooling performance. The similar 4715FS-23T-B50-D00 is a separate 230 VAC model and is not an automatic electrical replacement.
