Description

The San Jun SJ2509HA2 is a heavy-duty AC axial fan engineered for critical thermal management in industrial enclosures and machinery chassis. Designed by San Ju Electric Machinery, this 254mm unit delivers high-volume airflow required for heat dissipation in high-impedance systems. The fan features a robust die-cast aluminum frame and a high-temperature resistant motor architecture, ensuring longevity under continuous duty cycles. Its dual ball bearing system provides superior axial stability and reduced friction, directly contributing to an extended Mean Time Between Failures (MTBF). This specific model is optimized for 220V-240V AC operation, making it a standard fit for global industrial power grids. The unit is designed to replace or upgrade standard 25489 series fans, offering reliable exhaust performance in harsh environments.

Industrial Application:
The SJ2509HA2 is specifically deployed in high-load electrical cabinets, server racks, and CNC machinery control panels where passive cooling is insufficient. Its high static pressure capability allows it to overcome the resistance of dense dust filters and tightly packed components. By maintaining optimal operating temperatures, this Original Engineering component prevents thermal throttling and premature failure of sensitive power electronics such as VFDs and PLCs. We ensure Technical Compatibility with existing 254mm cutouts for seamless retrofitting. Contact us for current Lead Time and bulk availability.

Fans Maintenance and upkeep

1. The use environment should always be kept clean and tidy, the surface of the fan should be kept clean, there should be no sundries in the inlet and outlet air outlets, and the dust and other sundries in the fan and pipes should be cleaned regularly;

2. The fan can only operate under the condition that it is completely normal, and at the same time, it is necessary to ensure that the capacity of the power supply facilities is sufficient and the voltage is stable.

3. During the operation of the fan, if it is found that the fan has abnormal sound, the motor is seriously heated, the shell is live, the switch trips, and cannot be started, it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan, and a test run should be carried out for about five minutes after the overhaul to confirm that there is no abnormal phenomenon before starting the operation;

4. The fan should be stored in a dry environment to avoid moisture on the motor. When the fan is stored in the open air, there should be defensive measures. In the process of storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
