SUNON EEC0252B3-000U-A99 supports industrial equipment with DC brushless axial fan airflow. It is intended for installations where predictable air exchange is central to equipment stability.
The brushless DC motor architecture supports efficient electronic commutation and stable rotational performance for compact equipment cooling. Matching the fan curve to the finished airflow path supports efficient cooling without unnecessary speed or power consumption.
For an orderly design-in process, assess vibration transfer around EEC0252B3-000U-A99 and perform duty-point validation during prototype approval. The result is a clearer cooling specification for engineering, purchasing and maintenance teams. Record the intended operating point on the system resistance curve.
Use the listed voltage, size, 75 m³/h airflow, 2200 rpm, and 2 W input for preliminary comparison.
The workbook marks the product as RoHS compliant. Confirm UL, TUV, VDE, or other project-specific approvals for the exact suffix.
The exact IP or protection option is not stated in the supplied row. Confirm the full suffix in the applicable SUNON datasheet.
Speed-control capability is not stated for this complete part number. Confirm the signal and controller requirements before use.
Stock and lead time can change. Confirm the exact suffix, quantity, and delivery date with the supplier before ordering.
The listed speed is 2200 rpm. Confirm frequency, control method, and duty point for the installed system.
