ENGINEERING AND MATERIAL PROFILE
The AA1252MB-AT features a rugged die-cast aluminum alloy frame (painted black) for superior structural integrity and vibration dampening. The impeller is injection-molded from highly durable, flame-retardant PBT plastic (UL94V-0 rated). The integration of a premium dual ball bearing system extends the operational lifespan significantly compared to sleeve bearing alternatives, ensuring stable rotor dynamics and reduced mechanical friction. The shaded-pole AC motor is impedance protected to prevent burnout in the event of a locked rotor.

INDUSTRIAL APPLICATION AND TECHNICAL COMPATIBILITY
This ultra-thin cooling fan is specifically engineered for integration into narrow server chassis, telecommunications cabinets, CNC machine control panels, and automated test equipment (ATE). Its 25mm thickness solves critical clearance issues in densely packed enclosures while maintaining high volumetric airflow. The standard Ø 4.3 mm mounting holes ensure seamless Technical Compatibility with existing 120mm fan brackets, allowing for drop-in replacement during maintenance cycles.

PROCUREMENT AND LIFECYCLE VALUE
Designed for continuous 24/7 operation, the ADDA AA1252MB-AT minimizes system downtime and maintenance overhead. We maintain optimized inventory protocols to ensure a competitive Lead Time for both single-unit replacements and high-volume OEM production runs. All units are factory-new, guaranteeing authentic performance and compliance with global safety certifications including CE, UL, and RoHS.

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.
