Equipment builders can integrate SUNON EF80252B1-1000U-A99, a DC brushless axial fan, into industrial equipment. The design supplies the air movement required to carry component heat out of confined spaces.
The brushless DC motor architecture supports efficient electronic commutation and stable rotational performance for compact equipment cooling. Separating cool intake air from warm exhaust limits recirculation and improves heat-transfer effectiveness inside the equipment.
For EF80252B1-1000U-A99 integration, prioritize inlet clearance. Include replacement-fit checks in engineering approval, and confirm the full model interface before release. This supports reliable cooling and traceable purchasing. Verify mounting, connector and airflow direction against the replacement space.
Keep the airflow path clear, secure the frame without distortion, and follow the exact wiring diagram and voltage rating.
The worksheet lists 1.56 W input. Check supply capacity and operating conditions before commissioning.
The workbook marks the product as RoHS compliant. Confirm UL, TUV, VDE, or other project-specific approvals for the exact suffix.
Confirm any missing bearing, connector, control, IP rating, life, certification, and performance-curve details for the complete part number.
Match voltage, dimensions, mounting, airflow direction, airflow, pressure, connector, control signal, and protection before substitution.
Its documented 24 VDC rating and its 3200 rpm rating defines a lower-speed operating point. allow comparison with the required duty point without assuming unlisted options.

The EF80251S1-1000U-A99 is SUNON's 12 VDC, 80 × 80 × 25 mm DC axial fan option for telecom cabinets, base stations, and network equipment. Its 3200 rpm rating defines a lower-speed operating point. During airflow balancing, compare the model's volume-flow figure. Review connector, alarm, and sensor options separately.
