A filter element (64) between the core tube (50) snd the outer tube (54) stands on ribs (43) extending upward from the bottom end cap (42) and is spaced from the top end cap (56) by simllar ribs (57) extending downward from the top end cap (56), these ribs (43) (57) creating radial flow channels above and below the filter element.  The filter element (46) is wound spiral of filter material (62) and separator (63) forming a plurality of axial flow channels (66) (68).          Some of these axial flow channels (66) (68) are open at the top to receive liquid from the top radial flow channel and closed at the bottom, and some of the axial channels (66) (68) are closed at the top and open at the bottom to discharge llquid into the bottom radial flow channel.          Filter action is by way of radial flow, through the filter materlal, (62) from the open-top channels to the open-bottom channels.  The housing cover (22) is removable to remove and replace the filter (40).  Means (26) are provided to vent air from the system and to drain liquld from the system for removal and replacement of the filter (40) without having to clean the housing (10).
