Popis: The air charged through the air charger must be pure and free from impurities; hence, the role of a filter that removes pollutants, such as moisture, oil, and carbides is very important. The lifespan of the filter is approximately 50 h, and if exceeded, the purification function decreases rapidly. Therefore, it must be replaced periodically. However, economic and environmental problems occur in the process of replacing the filter. This study investigated the extension of the filter lifespan (60 h) and enhancement of the purification function. An auto drain system was installed. The pollutant discharge, maximum noise, and lifespan were confirmed through experiments and commissioned inspections to check the performance. The compatibility of the pollutant discharge function and the structure of the auto drain system was verified by checking the discharge of pollutants. In addition, the maximum noise was certified to be less than 80 dB according to the performance-standard. Finally, the charged air quality was analyzed after 60 h of use, and all the analyzed values were confirmed to be within the performance-standard range.
