SANYO DENKI positions 109R0812S402 as a DC axial fan for servers, storage systems and ICT equipment. It helps equipment designers manage local hot spots where natural convection is insufficient.
The rated peak airflow of 71.4 m3/h combines with 48.1 Pa pressure capability to support useful flow after installation losses are considered. Selection should include a system-resistance review, mounting check and harness confirmation. The full model code matters because signal and lead options can differ within a series.
Check exhaust separation from the intake zone. The outcome supports dependable long-term equipment service. Confirm the final fan curve in the assembled equipment. Preserve clear inlet and outlet space during installation.
For server chassis and computing nodes, 109R0812S402 provides a dedicated forced-air cooling path. Directed airflow carries component heat toward the equipment exhaust and helps maintain a controlled internal temperature. The application supports stable equipment service.
SANYO DENKI 109R0812S402 serves storage arrays and data appliances that operate with sustained internal heat. Directed airflow carries component heat toward the equipment exhaust and helps maintain a controlled internal temperature. The application supports stable equipment service.
109R0812S402 is suitable for network and other ICT hardware. Reliable ventilation reduces hot spots around sensitive electronics and supports consistent equipment availability. The application supports stable equipment service. Selection should follow the approved full model code.
Check its 80 × 80 × 25 mm size, 71.4 m³/h airflow, 48.1 Pa pressure, mounting points, airflow direction, and system resistance.
It is listed for servers, UPS systems, and telecom equipment. Confirm airflow, pressure, dimensions, and environmental conditions against the actual equipment.
No exact IP rating is supplied for this model row. Check the current model datasheet before use in water, dust, or oil exposure.
Inspect dust buildup, airflow blockage, abnormal noise, mounting security, and wiring condition; disconnect power before service.
Compare its listed power with the required airflow, pressure, and operating hours. System-level savings depend on correct duty-point selection.
