Abstract: A filter element for cleaning an operating liquid of a machine tool is provided with a pressure-stable jacket permitting flow therethrough. A filter medium is arranged in the pressure-stable jacket. A first end disc and a second end disc are seal-tightly connected to opposite ends of the filter medium. The filter medium surrounds an inner raw-side cavity. The pressure-stable jacket surrounds the filter medium and is connected fixedly to the first and second end discs. The first end disc has an inlet opening for the operating liquid. The second end disc has a drainage opening provided with a releasable closure element that closes the drainage opening.

Abstract: A secondary filter element for a filter arrangement is provided with a filter medium and a circumferentially extending sealing device that seals the secondary filter element in respect to a filter receptacle of the filter arrangement. The circumferentially extending sealing device has an oval geometry with a long side and a short side. The circumferentially extending sealing device has an outer surface projecting, in a radial direction of the secondary filter element, farther past the filter medium when viewed along the short side compared to when viewed along the long side. A filter arrangement has a filter receptacle. A main filter element is received in the filter receptacle, and a secondary filter element is received in the main filter element. The circumferentially extending sealing device of the secondary filter element projects in a radial direction of the secondary filter element outwardly past an interior of the main filter element.

Abstract: An air filter has a round housing that is coaxial to a central axis of the air filter. The housing has a housing bottom part and a detachable housing cover. A round filter element is received in the housing. The housing bottom part has a tubular housing wall with an open end and an outlet-side axial end provided with a central outlet socket positioned axially opposite to the open end. Through the outlet socket, air exits from the air filter after filtration. The housing cover closes off the open end. A raw air region with annular cross section is formed between round filter element and inner side of the tubular housing wall. The housing cover has an annular or ring section-shaped air inlet region with inflow openings through which air to be filtered enters the housing without deflection in a direction coaxially or parallel to the central axis.

Abstract: A filter holder (2) for a filter element (3) that has an oval-shaped cross section transverse to a longitudinal direction (LR) thereof, with a receiving section (19) for receiving the filter element (3), a fluid inlet (24) for allowing fluid (L) to be filtered into the filter holder (2), and a fluid outlet (25) for letting the fluid (L) filtered with the aid of the filter element (3) out of the filter holder (2), wherein the fluid inlet (24) is arranged such that an inflow direction (E) of the fluid (L) to be filtered is oriented in the direction of a lateral surface (29) of the filter element (3) that can be received in the receiving section (19), whereby the fluid (L) to be filtered flows tangentially around the filter element (3) that can be received in the receiving section (19) in order to separate particles (33) contained in the fluid (L) to be filtered on a wall (30) of the receiving section (19) with the aid of centrifugal force.
