Abstract: Disclosed is a desiccant cartridge (10) for drying and de-oiling a gaseous fluid, and a method for flow guidance within the desiccant cartridge. The desiccant cartridge and a housing (12) having positioned therein an inner pot (28) in which an oil separating medium (50) for oil particles contained in the fluid and a desiccant (52) for drying the gaseous fluid are arranged one after the other in the direction of the housing longitudinal axis (14). The housing (12) has a housing base (18) having a centrally arranged inlet (20) for the fluid to be dried and de-oiled and having eccentrically arranged outlet openings (24) for the dried and de-oiled fluid. During normal operation of the desiccant cartridge (10), the gaseous fluid guided into the desiccant cartridge (10) via the central inlet (20) is first guided in a flow through the oil separating medium (50) and then through the desiccant (52).

Abstract: An exchangeable filter has a filter housing, a filter element, and a connecting member arranged at a filter housing end face. A filter-associated connecting part of a connecting device detachably connects the exchangeable filter with a filter head of a filter device by a plug-in/rotary movement. A filter-associated locking part of a locking device locks the connecting device in a locked state automatically and releasably by the plug-in/rotary movement with a head-associated locking part of the locking device provided at the filter head. The filter-associated locking part has a latching section latching with a head-associated latching section of the head-associated locking part. The filter-associated locking part has a support section on a side of the filter-associated locking part facing away radially from the filter-associated latching section. The support section radially supports the filter-associated locking part relative to the circumferential section of the filter housing in the locked state.
