Ensure that the power supply parameters (such as voltage and current) of the fan match the power supply system of the equipment to avoid performance degradation or damage caused by power supply mismatch.
**3.3 Noise Requirements**
Choose a fan with low noise design according to the noise limit of the application scenario. Low noise operation is particularly important in medical and household scenarios.
**3.4 Control method**
According to the control requirements of the equipment, select a fan that supports PWM or voltage regulation to achieve precise control and flexible adjustment of wind speed.
**4. Maintenance and care**
In order to ensure the long-term stable operation of the small DC brushless blower, regular maintenance and care are essential:
**4.1 Regular cleaning**
- - Clean the fan housing and air inlet regularly to prevent dust and debris from accumulating and affecting performance.
- - The impeller and internal structure can be cleaned with compressed air or a soft-bristled brush.
**4.2 Check the connection parts**
- - Check the power cord, connector and drive connections regularly to ensure that they are not loose or damaged.
- - Mounting screws and fixings should be tightened regularly to prevent loosening due to vibration.
**4.3 Lubrication and wear inspection**
- - For parts that require lubrication, add an appropriate amount of lubricating oil regularly to reduce friction and wear.
- - Check the wear of the impeller and bearings and replace damaged parts in time.
**4.4 Operation Status Monitoring**
- - Regularly monitor the operating status of the fan, including parameters such as noise, vibration and temperature.
- - If any abnormal situation is found (such as increased noise, increased vibration or excessive temperature), the machine should be stopped immediately for inspection and troubleshooting.
**Conclusion**
Small DC brushless blowers play an important role in the fields of medical, household, industrial and automotive industries due to their high efficiency, energy saving and compactness.
