The San Ace 109E5724K502 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.
The rated peak airflow of 504 m3/h combines with 243 Pa pressure capability to support useful flow after installation losses are considered. Procurement teams should match the entire part number to the approved specification. Thermal testing in a representative chassis confirms cooling margin before volume release.
Confirm inlet clearance around nearby cables. It helps engineering and procurement use one specification. Confirm the final fan curve in the assembled equipment. Preserve clear inlet and outlet space during installation.
For server chassis and computing nodes, 109E5724K502 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.
SANYO DENKI 109E5724K502 serves storage arrays and data appliances that operate with sustained internal heat. 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.
109E5724K502 is suitable for network and other ICT hardware. These systems need continuous heat removal because compact layouts and rising power density restrict natural convection. It provides a practical cooling path for OEM integration. Selection should follow the approved full model code.
The worksheet lists 243 Pa. Use the official curve to match it to system resistance.
Evaluate the exact bearing, life, temperature, alarm, and protection data. Correct sizing and clean airflow are also required for reliable operation.
Match voltage, size, mounting, airflow direction, airflow, pressure, connector, control signal, and protection before substitution.
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.
