To keep the compressed air system clean and enhance the compressed air quality, a combined set of high-quality, high-performance filter and drain valve are used. Compacted filters are used to remove water, grease, and foreign substance in the compressed air, however, compressed water molecules are too tiny to be prevented from penetrating through the filter. Furthermore, even though the larger particle such as grease, rust particle, and foreign substance are blocked and attached to the filter, eventually it will clog the filter, and results in a larger pressure reduction to the compressed air, further increase the maintenance cost to replace the filter.
