Final line filters in instrument air systems should be rated for what particle size?

Final line filters in instrument air systems are crucial for ensuring the quality and purity of the air that is used in sensitive equipment and instrumentation. These systems demand filters that can effectively remove extremely fine particles to prevent contamination that could affect the performance of the instruments.

Filters rated for 0.01 micron are particularly effective at capturing very small particles, including aerosols and contaminants that could compromise the system. This level of filtration is essential in high-precision environments where even minuscule impurities can lead to malfunctions or inaccurate readings.

Filters with higher micron ratings, such as 0.1 micron, 1 micron, or 10 microns, do not provide the necessary level of filtration for critical applications. While they may capture larger particles, they are insufficient for ensuring the cleanliness required in instrument air systems, where the integrity of the air supply is paramount.
