The invention relates to a disc shaped filter element for filtering a liquid such as a polymer. The filter element comprising&#x2014;a hub, said hub defining a central opening therethrough, &#x2014;an upper filter medium and a lower filter medium, said upper filter medium and said lower filter medium extending radially outwards from said hub. The upper filter medium and the lower filter medium comprise a layered structure comprising a first layer and a second layer. The first layer comprises a non-sintered metal fiber fleece and the second layer comprises a layer of non-sintered metal powder particles. The first layer and the second layer are sintered together.

An elongate mesh pack for filtering a fluid defines a mesh pack axial opening. The mesh pack comprises a filter medium for filtration of the fluid and has an end fitting securely fixed to the filter medium, the end fitting providing a first extremity of the mesh pack. The end fitting has an inner surface defining an end fitting opening through the end fitting, the end fitting opening being co-axial with the axial opening of the mesh pack. The end fitting comprises an annular recess encompassing the end fitting opening. A partition wall suitable to deform towards the recess under radial force is provided between the recess and the end fitting opening, the partition wall forming at least part of the inner surface.

A filter candleas subject of the present invention comprises: an elongated mesh packfor filtering a fluid, comprising an end fittingsecurely fixed to a filter medium. Further, a hollow core tubeis provided having a fluid permeable wall, the core tube being positioned within the axial opening of the mesh pack. The core tubehas an end flangefixed to the outer end surface, which end flange is suitable for engaging the end fittingon the mesh pack. A ring-shaped sealis provided between and making contact with the outer end surface of the core tube, the end fitting and the end flange. The seal is a porous ring-shaped structure comprising a multitude of pores, which pores have an average pore size being equal or less than the filter rating of the filter medium.
