Compressed air finds application in texturizing products, drying sterilized equipment, shaping containers, conveying ingredients through pipelines, and forming protective barriers around products stored in tanks. However, despite its importance, compressed air can also serve as a primary source of contamination.

It is crucial to maintain the dryness and freedom from oil in compressed air to ensure product quality and safety. Typically, achieving this goal necessitates a sequence or “train” of filters and dryers. While each facility’s requirements may vary, the appropriate treatment often involves pre-filtration in the utility room, along with point-of-use filtration before compressed air comes into contact with a product.
