The San Ace 109R0812G4021 serves servers, storage systems and ICT equipment as a DC axial fan. Its airflow supports heat transfer from internal devices toward cabinet or chassis exhaust openings.
Its 88.8 m3/h maximum airflow supports rapid air exchange, while 80.4 Pa pressure capability helps overcome resistance within the finished equipment. Procurement teams should match the entire part number to the approved specification. Thermal testing in a representative chassis confirms cooling margin before volume release.
Check startup demand against the power supply. This provides buyers with a traceable selection basis. Confirm the final fan curve in the assembled equipment. Preserve clear inlet and outlet space during installation.
SANYO DENKI 109R0812G4021 serves server chassis and computing nodes 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.
109R0812G4021 is suitable for storage arrays and data appliances. 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.
The San Ace 109R0812G4021 supports thermal management in 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.
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.
Its 12 VDC rating and documented 80.4 pa maximum pressure is the most distinctive duty-point parameter. provide model-specific selection data without relying on unlisted claims.
The worksheet lists 12 VDC. Check polarity or AC frequency and the wiring diagram before commissioning.
The listed speed is 4500 rpm. Confirm control conditions and the actual duty point.
Confirm full suffix, voltage, connector, control signal, bearing, IP rating, certifications, stock, and required delivery date.
