Description

The ADDA AD1248HB-F91GP is a high-performance DC brushless axial fan engineered specifically for the rigorous thermal demands of industrial frequency converters and variable frequency drives (VFDs). Manufactured by ADDA Corporation in Taiwan, this model utilizes a robust 120mm chassis designed to deliver high static pressure, essential for forcing air through dense heatsink fin arrays and IGBT modules where airflow resistance is significant. The unit features a precision Dual Ball Bearing system, which ensures functional integrity without maintenance over extended lifecycles, significantly outperforming sleeve bearing alternatives in continuous-duty environments. Its 48V DC electrical profile allows for direct integration into telecom-grade power backplanes and high-voltage industrial control cabinets. By maintaining optimal operating temperatures, this fan prevents thermal throttling in power electronics. We provide Original Engineering components to ensure exact Technical Compatibility with your existing cooling assemblies. Contact our team for current stock levels and Lead Time information.

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.
