Common Characteristics
В процеса на сгъстяване на въздуха е възможно попадането на известно количество масло в него, което се отсранява в последствие чрез линейни филтри за сгъстен въздух. Ефективността на филтрите е в зависимост от типа на компресора, неговата възраст, условията на експлоатация и пр.
