Filter Assembly

Filter assembly for a liquid medium comprising a filter housing made-up from a first and a second housing part, each part having a first and second end wall respectively, surrounded by a circumferential wall, which housing parts in combination surround in the space defined by the end walls three layers of filter material, and having further an outlet and an inlet for the medium to be filtered, and comprising within this space a spacer element with an open structure and upstanding ribs between which chambers are defined, interconnected via cut-outs in these ribs,

• in which the respective end edges of the ribs define a first and a second end plane, which first end plane defines a (first) abutment plane for a first layer of filter material and which second end plane defines a (second) abutment plane for a second layer of filter material
• a fluid passage being provided through this spacer and the layers of filter material, crossing the respective main planes thereof,
• a first layer of filter material lying between the first abutment plane and the first end wall,
• a second layer of filter material lying between the second abutment plane and the second end wall, and with
• between the second layer of filter material and the second end wall a third layer of filter material while
• the space between the third layer of filter material and the second end wall, and the chambers in the spacer, are in connection with the outlet of the filter and
• the space between the first layer of filter material and the first end wall is connected to the filter inlet,
• wherein the spacer element extends across the entire inner space of the filter housing and the respective second and third layers of filter material each constitute a discrete, independent layer of which the respective end edges are sealingly interconnected and which second and third layer extend, together with the spacer element, across the entire inner space of the filter housing.
