Sanyo Denki 109R0812G402 combines a 80 × 80 × 25 mm DC axial fan platform with a 12 VDC rating for servers, UPS systems, and telecom equipment. High airflow is highlighted together with a high-static-pressure design. 80.4 Pa maximum pressure is the most distinctive duty-point parameter. Selection focus: selection criteria review motor input.

SANYO DENKI positions 109R0812G402 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.
A listed maximum airflow of 88.8 m3/h and maximum pressure of 80.4 Pa give engineers a clear basis for matching the fan to enclosure resistance. 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.
Verify mounting rigidity under continuous duty. The check aligns mechanical fit with cooling duty. Confirm the final fan curve in the assembled equipment. Preserve clear inlet and outlet space during installation.
109R0812G402 is suitable for server chassis and computing nodes. Air circulation around processors, power devices and control electronics limits heat concentration and supports stable operation. It provides a practical cooling path for OEM integration.
The San Ace 109R0812G402 supports thermal management in storage arrays and data appliances. Air circulation around processors, power devices and control electronics limits heat concentration and supports stable operation. It provides a practical cooling path for OEM integration.
For network and other ICT hardware, 109R0812G402 provides a dedicated forced-air cooling path. Air circulation around processors, power devices and control electronics limits heat concentration and supports stable operation. It provides a practical cooling path for OEM integration.
The worksheet lists 4.44 W. Check supply capacity and operating conditions before commissioning.
Verify supply, connector, obstructions, impeller movement, and alarm or protection status using the model-specific troubleshooting data.
Confirm full suffix, voltage, connector, control signal, bearing, IP rating, certifications, stock, and required delivery date.
Check its 80 × 80 × 25 mm size, 88.8 m³/h airflow, 80.4 Pa pressure, mounting points, airflow direction, and system resistance.
The workbook marks it RoHS compliant. Confirm model-specific UL, CSA, TÜV, or other required approvals from official documentation.
