109R0805F401 brings San Ace DC axial fan cooling to servers, storage systems and ICT equipment. The compact air-moving design suits OEM assemblies that require continuous ventilation around electronic and power components.
The rated peak airflow of 54.6 m3/h combines with 28.4 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.
Assess vibration transfer into enclosure panels. This step reduces uncertainty during equipment qualification. Confirm the final fan curve in the assembled equipment.
For server chassis and computing nodes, 109R0805F401 provides a dedicated forced-air cooling path. These systems need continuous heat removal because compact layouts and rising power density restrict natural convection. The application supports stable equipment service.
SANYO DENKI 109R0805F401 serves storage arrays and data appliances that operate with sustained internal heat. These systems need continuous heat removal because compact layouts and rising power density restrict natural convection. The application supports stable equipment service.
109R0805F401 is suitable for network and other ICT hardware. Directed airflow carries component heat toward the equipment exhaust and helps maintain a controlled internal temperature. The application supports stable equipment service. Selection should follow the approved full model code.
Evaluate the exact bearing, life, temperature, alarm, and protection data. Correct sizing and clean airflow are also required for reliable operation.
Review ambient temperature, airflow restriction, contamination exposure, noise limit, mounting orientation, and maintenance access.
Inspect dust buildup, airflow blockage, abnormal noise, mounting security, and wiring condition; disconnect power before service.
Availability and lead time can change. Confirm the exact suffix, quantity, and delivery date with the supplier before ordering.
The worksheet lists 26 dB. Enclosure acoustics, system resistance, and distance can change the installed result.
