Description

The ADDA AD1224LB-A71GL is a high-reliability DC brushless axial fan engineered for precision thermal regulation in industrial electronics and telecommunications infrastructure. This unit features Original Engineering from ADDA Corporation, utilizing a robust Dual Ball Bearing system that significantly extends Mean Time Between Failures (MTBF) compared to sleeve bearing counterparts, making it suitable for continuous duty cycles. The 120mm form factor combined with a 24V DC winding makes it a standard fit for automation control cabinets and server rack cooling. The ‘LB’ classification denotes a Low-Speed, Ball Bearing configuration, specifically calibrated to balance airflow volume with acoustic output, ensuring Technical Compatibility with noise-sensitive laboratory equipment and office-adjacent server rooms. Sourcing authentic components ensures adherence to PBT UL94V-0 flammability standards and consistent electrical performance. Contact us for current Lead Time and volume availability.

INDUSTRIAL APPLICATION
This fan is specifically optimized for cooling 24V DC power supply units (PSUs) and Variable Frequency Drives (VFDs) within enclosed control panels. The low-current draw (0.14A) minimizes load on the auxiliary power circuit, while the ball bearing construction withstands the elevated temperatures and vertical mounting orientations often found in factory automation cabinets. This solves the critical issue of thermal accumulation in sealed enclosures without introducing excessive acoustic noise to the operator environment.

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.
