The SUNON DP201A 2123HBT.GN reinforces data centers and communication hardware as an AC axial fan, combining a constrained-space forced-air cooling role with a clear mechanical and electrical integration path.
This helps designers translate moving air into lower component temperature, steadier running and a more repeatable hardware design.
The straight-through moving air geometry simplifies integration into panels, cabinets and hardware zones that need broad air exchange.
Listed moving air of 147.81 / 181.79 m3/h and pressure of 64.76 / 79.71 Pa provide starting points for duty-point evaluation in the completed application. Preserve the specified moving air direction during assembly. Review the approved electrical interface for the complete suffix.
OEM designs for servers and data-communication hardware use DP201A 2123HBT.GN where a AC axial fan must cools computing and network assemblies. Stable air movement helps maintain component temperature as electrical load and ambient conditions change.
The SUNON AC axial fan DP201A 2123HBT.GN addresses thermal demand in power supplies, inverters and control cabinets by helping to cools power modules and controls. System developers should verify mounting, ventilation flow direction and system resistance to preserve the intended application value.
When fitted in industrial automation machinery, DP201A 2123HBT.GN ventilates drives and production electronics within the available machinery space. The machinery needs a practical balance between air delivery, pressure capability, sound and electrical consumption.
When production in medical and laboratory instruments, DP201A 2123HBT.GN cools enclosed instrument electronics within the available assembly space. Effective ventilation reinforces process continuity by keeping electronics and power devices within their intended temperature range.
The product is classified as a axial fan. Use the full model code because nearby variants can differ in motor, mounting, and controls.
No exact IP protection level is stated for this item in the supplied sources. Confirm it before use in dusty, wet, or harsh locations.
The upload row lists 45 / 50 dB. Confirm the measurement condition and compare noise at the intended operating point.
The matched source highlights 45 / 50 dB noise data recorded for this model. Compare that point together with the listed electrical and dimensional data.
The supplied row lists 147.81 / 181.79 m³/h airflow, 64.76 / 79.71 Pa pressure, 20 / 19 W input, 2750 / 3050 rpm, 45 / 50 dB. Compare these values with the real system operating point, not only the free-air rating.
Compare the full model suffix, voltage, size, motor or controller type, mounting, airflow, pressure, power, speed, and protection; do not copy data from a similar model.
