 I. Product Specifications and Performance

1. **Basic Parameters**

   - **Dimensions**: 120mm × 120mm × 38mm (width × height × thickness), in line with industrial standard installation dimensions.

   - **Voltage/Frequency**: AC220V/50Hz, compatible with power grid standards in China and most countries.

   - **Power and Rotational Speed**: Power is 16W, rotational speed is 2600 RPM, and air volume can reach 144 CFM (about 245 m³/h), balancing heat dissipation efficiency and energy consumption.

   - **Noise Control**: The operating noise is 39 dB, with a silent design, suitable for work environments sensitive to noise.

2. **Bearing Types and Service Life**

   - **Ball Bearing (model suffix B)**: Has a long service life of up to 50,000 hours, resistant to high and low temperatures (-30℃ ~ +65℃), suitable for long-term high-load operation.

   - **Oil-Impregnated Bearing (model suffix S)**: Has lower noise (about 31 dB) but a shorter service life (30,000 hours). It needs regular lubricating oil replenishment and is applicable to a temperature range of -10℃ ~ +60℃.

3. **Environmental Adaptability**

   - Operating altitude ≤ 2000 meters, pollution degree 2, and can operate stably in general industrial environments.

   - The protection level is not clearly marked, but the material is flame-retardant plastic, which has a certain anti-corrosion ability.

II. Application Scenarios

1. **Core Uses**

   - Forced heat dissipation of electrical cabinets and distribution boxes to prevent internal components from aging due to overheating.

   - Ventilation systems of mechanical equipment (such as electric welders, CNC machine tools) to maintain a stable operating temperature.

   - Auxiliary heat dissipation of communication equipment and server cabinets to ensure the stability of data transmission.

2. **Installation Suggestions**

   - Sufficient space (recommended ≥ 10cm) should be reserved around the fan to avoid air flow blockage affecting heat dissipation efficiency.

   - Installation should be carried out by professionals to ensure firm wiring and avoid poor contact due to vibration.

 III. Purchase and Maintenance

1. **Price and Channels**

   - **Ball bearing model**: The unit price is about 100-132 yuan.

   - **Oil-impregnated bearing model**: The unit price is about 80-110 yuan.

   - Pay attention to distinguishing the model suffixes (B for ball bearing, S for oil-impregnated bearing) to avoid confusion.

2. **Maintenance Points**

   - **Ball bearing**: No regular lubrication is needed, but the dust on the blades should be cleaned every six months to prevent air volume attenuation.

   - **Oil-impregnated bearing**: It is recommended to drop sewing machine oil or special lubricant into the bearing every 3 months to extend the service life.

   - If the fan speed drops abnormally, it may be due to capacitor failure or bearing wear, and the corresponding components should be replaced in time.

IV. Notes

1. **Safety Specifications**

   - It is strictly forbidden to use in flammable, explosive and humid environments to avoid the risk of short circuit.

   - Do not touch the fan blades during operation to prevent mechanical injury.

2. **Compatibility Check**

   - Confirm that the equipment voltage is consistent with the fan specification (AC220V) to avoid burning the motor.

   - Measure the installation hole distance (120mm × 120mm, hole diameter φ5.5mm) before installation to ensure it matches the cabinet.

With the characteristics of high air volume, low noise and long service life, this fan has become one of the mainstream choices for industrial heat dissipation. Users can choose the bearing type according to specific needs (such as budget, noise requirements) and purchase through regular channels to ensure genuine products and after-sales support.

 V. Key Comparative Parameters

VI. Notes

1. **Compatibility Check**:

   - Confirm that the equipment voltage is consistent with the fan to avoid motor burnout due to overvoltage.

   - Measure the cabinet hole distance before installation to ensure the 120mm × 120mm installation position matches.

   - Do not touch the fan blades during operation; it is recommended to install a protective net.

3. **Troubleshooting**:

   - If the air volume drops sharply, check whether the blades are dusty or the bearings are stuck.

   - When the noise increases abnormally, it is better to replace the bearing first rather than the whole machine.
