Claim 16:
17. A filtering system for filtering gases contaminated with particles produced in manufacturing processes, the filtering system comprising:
a production room having a gas inlet connected to a gas supply circuit and a gas outlet; and
a filter device including
a first filter circuit being connected in fluid communication to the gas outlet of the production room, having a first gas filter element capable of filtering the particles from a gas exiting the gas outlet and having a first receptacle connected to the first gas filter element and capable of receiving at least a part of the particles from the first gas filter element; and
a second filter circuit having a first oil filter element capable of filtering oil with particles obtained in a back-flushing process of the first gas filter element, the first oil filter element having a filtrate side and an unfiltered side connected in fluid communication with the first receptacle such that cleaned oil is capable of flowing from the filtrate side of the first oil filter element to the first receptacle and such that oil contaminated with the particles is capable of flowing to the unfiltered side of the first oil filter element from the first receptacle.
