Fans play a central role in particulate matter sampling, mainly used to control the sampling airflow, maintain stable flow, and ensure efficient passage of particulate matter through filtration systems or collection devices.
1. Power source:
Provide stable airflow power, draw air into the sampling device, and carry particulate matter through the filter membrane or collector.
2. Flow control:
By adjusting the fan speed or air pressure, maintain a constant sampling flow rate (such as 100 L/min) to ensure the accuracy of sampling volume and concentration calculation.
3. Sampling uniformity:
Optimize airflow distribution, reduce turbulence, and avoid particle deposition or loss in the sampling pipeline.
4. Adapt to complex environments:
To cope with high altitude (low pressure), high temperature and high humidity scenarios, the sampling efficiency is ensured by dynamically adjusting the air volume.
5. Requirements for volume and weight
Due to the fact that atmospheric sampling and particle sampling mostly require instruments to be carried to relatively high altitudes for operation, it is necessary for instruments to meet performance requirements while being as convenient as possible.
