Water content of compressed air in electronics factory

In electronics plants, the moisture content of compressed air is a key indicator, which is directly related to the normal operation of production equipment and product quality. Generally speaking, electronics factories have strict requirements on compressed air, and their moisture content should be controlled at an extremely low level.

Electronics factory compressed air moisture content standards:

• High-tech fields (such as electronics, semiconductors, etc.): These fields have extremely high requirements for compressed air, and the moisture content should usually be controlled below 10PPM.

Factors affecting the moisture content of compressed air:

• Ambient humidity: The moisture content in the air will directly affect the moisture content of compressed air. The higher the ambient humidity, the more moisture it may bring in the compressed air.
• Compression process: The volume of the air decreases, the pressure increases, and the temperature will also change. A decrease in temperature during cooling will lead to an increase in relative humidity. When the relative humidity reaches 100%, the water vapor in the air will begin to condense into liquid water.
• Post-treatment Equipment: Post-treatment equipment such as dryers and filters plays a key role in reducing the moisture content in compressed air. If these devices fail or operate abnormally, the moisture content in the compressed air will increase.

How to reduce the moisture content of compressed air:

1. Select the right air compressor: Choose an air compressor with efficient dehumidification capabilities, such as an oil-free water lubricating air compressor, which can reduce the moisture in the compressed air from the source.

2. Installation of post-treatment equipment: Install high-quality dryers (such as cold dryers, adsorption dryers, etc.) and filters at the outlet of the air compressor to further remove moisture and impurities from the compressed air.

3. Strengthen maintenance: Regularly maintain and maintain the air compressor and after-treatment equipment, such as replacing the desiccant, cleaning the filter element, etc., to ensure that the equipment is in good operation.

4. Optimize pipeline and storage design: Rationally design pipelines and storage systems to reduce the accumulation and retention of moisture in the pipeline. At the same time, a drain valve is installed at the low point of the pipeline to discharge condensate regularly.

Summary:

Electronics factories have extremely high requirements for the moisture content of compressed air.It should usually be controlled below 10PPM. In order to ensure that the moisture content of compressed air meets the requirements, it is necessary to select appropriate air compressors, install post-treatment equipment, strengthen maintenance and optimize pipeline and storage design. The implementation of these measures will help ensure the normal operation of production equipment and product quality.
