Designed around the cooling needs of data centers and communication hardware, the SUNON DP201AT 2122HBT.GN provides an AC axial fan format for OEM hardware integration.
Air enters and leaves in the axial direction, supporting efficient exchange across open enclosures, electronics and ventilation paths.
Listed ventilation flow of 112.13 / 135.92 m3/h and pressure of 34.87 / 42.35 Pa provide starting points for duty-point evaluation in the completed application.
Production approval should consider mounting, connector or lead arrangement, ventilation flow direction and access for future service. Preserve the specified ventilation flow direction during assembly. Review the approved electrical interface for the complete suffix.
The application of DP201AT 2122HBT.GN covers servers and data-communication hardware; here, the AC axial fan cools computing and network assemblies. Consistent cooling reduces thermal stress around assemblies that cycle between standby and high-load running.
In power supplies, inverters and control cabinets, the SUNON DP201AT 2122HBT.GN provides forced air delivery that cools power modules and controls. Maintaining clear inlet and outlet space helps the assembled installation realize the expected thermal management benefit.
The application of DP201AT 2122HBT.GN covers industrial automation hardware; here, the AC axial fan ventilates drives and production electronics. The application needs predictable ventilation flow because dense layouts restrict natural convection and heat spreading.
For installation in medical and laboratory instruments, SUNON DP201AT 2122HBT.GN acts as a temperature management component that cools enclosed instrument electronics. The application values controlled ventilation because internal space and acoustic limits constrain temperature management choices.
Available performance data includes 112.13 / 135.92 m³/h airflow, 34.87 / 42.35 Pa pressure, 18 / 16.5 W input, 2150 / 2500 rpm, 44 / 48 dB. Obtain the full curve when system resistance or part-load behavior matters.
Confirm the target equipment, operating point, ambient conditions, installation space, electrical supply, controls, protection, quantity, and required delivery date.
The upload sheet marks the item as In Stock, but available quantity should be confirmed when the order is placed.
The upload row lists 220–240 VDC. Confirm phase, frequency, terminals, and local supply conditions before wiring.
Check supply voltage, controller signals, blocked airflow, contamination, abnormal noise, rotation, and the equipment operating point before replacing the unit.
No guaranteed lead time is provided in the supplied sources. Confirm current stock, required quantity, production schedule, and shipping date with the supplier.
