Abstract

A filter assembly (1) comprises a fluid tight housing (6, 7). First and second coupling means (10 and 11) are provided on the housing, each coupling means providing adjacent flow channels into the housing. A filter element is located within the housing, the element having a fluid tight external wall (20) and a filter medium (19) housed within the wall. A first flow path is established between the first and second coupling means through the filter element, while a second flow path between the first and second coupling means is established within the housing but outside the external wall of the filter element.
