SANYO DENKI positions 109S-303 as a AC axial fan for automation controls, PLC cabinets and drive systems. It helps equipment designers manage local hot spots where natural convection is insufficient.
Its 379.8 m3/h maximum airflow supports rapid air exchange, while 196 Pa pressure capability helps overcome resistance within the finished equipment. 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.
Preserve outlet space to limit recirculation. It supports stable operation across the intended load cycle. Confirm the final fan curve in the assembled equipment. Preserve clear inlet and outlet space during installation.
SANYO DENKI 109S-303 serves automation and electrical control cabinets that operate with sustained internal heat. These systems need continuous heat removal because compact layouts and rising power density restrict natural convection. It supports reliable OEM equipment cooling.
109S-303 is suitable for PLC and motion-control equipment. Directed airflow carries component heat toward the equipment exhaust and helps maintain a controlled internal temperature. It supports reliable OEM equipment cooling. Selection should follow the approved full model code.
The San Ace 109S-303 supports thermal management in inverters and industrial drive systems. Directed airflow carries component heat toward the equipment exhaust and helps maintain a controlled internal temperature. It supports reliable OEM equipment cooling.
The worksheet lists 56 dB. Enclosure acoustics, system resistance, and distance can change the installed result.
The listed speed is 3500 rpm. Confirm control conditions and the actual duty point.
Confirm connector and mounting details, keep the airflow path clear, and isolate power before cleaning or service.
Use rated voltage, 172 × 150 × 51 mm dimensions, 379.8 m³/h airflow, 3500 rpm, and 25 W input for preliminary comparison.
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.
