Abstract: A filter housing of a fluid filter has a housing body with inlet and outlet openings for fluid. The housing body has an element receptacle for a filter element that separates inlet opening from outlet opening. The housing body has an installation opening providing access to the element receptacle in an installation direction and enabling insertion of the filter element into the element receptacle. The installation opening is arranged at a transverse side of the housing body laterally relative to a housing axis that is transverse to the installation direction. A housing cover closes off the installation opening. The housing body has a sealing surface contacting a seal of the filter element when inserted in the element receptacle and surrounding the housing axis at least partially circumferentially. A fall-out protection device prevents the filter element from falling out of the element receptacle when the installation opening is open.

Abstract: A filter assembly has a housing with a housing inlet and a drain. A rotary vessel is rotatably mounted within the housing and has a rotary vessel inlet and a rotary vessel outlet. Fluid exiting the rotary vessel outlet exits the housing through the drain. A valve assembly moveable between a closed and an open configuration is provided. When closed, the valve assembly fluid-tightly seals rotary vessel inlet from housing inlet. When open, the rotary vessel inlet is in fluid communication with the housing inlet such that fluid flowing into the housing inlet passes into the rotary vessel inlet. The valve assembly is moveable from closed to open configuration when a pressure of fluid flowing into the housing inlet exceeds a threshold pressure. The filter assembly has a fluid passageway permitting air flow into the rotary vessel through the rotary vessel inlet when the valve assembly is closed.
