摘要： A combination (10) of a replaceable filter element (21) and a core element (38) is provided, the filter element comprising a tubular wall (25) of filtration medium for collecting material in a fluid stream passing through the tubular wall (25), a first end part (26) and a second end part. The core element (38) comprises a perforated tube (39) having transverse outer dimensions smaller than transverse inner dimensions of the tubular wall (25), and a bypass valve member (35) provided at one end of the perforated tube (39). The bypass valve member (35) is tubular and moveably attached to the perforated tube (39) for movement in axial direction with respect to the perforated tube (39) between an extended position and a retracted position. The first end part (26) of the filter element (21) comprises an axial passage (29) configured to receive the bypass valve member (35) slideable and sealingly.
