摘要： A purification column is provided in which fluid is purified by flow through a purifying component. The column includes an annular wall defining a bore which, in use, contains the purifying component. The column further includes an inlet port to the bore comprising a first aperture through the annular wall, the inlet port being adjacent one end of the column. The column further includes an outlet port from the bore comprising a second aperture through the annular wall, the outlet port being adjacent the same end of the column as the inlet port. The column further includes a flow guidance device within the bore and removably connected to the inlet and outlet ports for guiding the fluid to the purifying component from the inlet port and for guiding the fluid from the purifying component to the outlet port. The flow guidance device maintains separation of the fluid flows to and from the purifying component.

摘要： A filter assembly for collecting material entrained in a fluid stream includes a filter element having a tubular filter and an end cap providing a flow conduit which extends between first and second conduit openings communicating with the internal void of the tubular filter. A housing for the filter element has inlet and outlet ports for the fluid stream, a housing bowl in which the tubular filter is located, and a housing head which provides at least one of the ports as a docking port for the first conduit opening. The housing head and end cap are arranged such that the end cap is inserted into the housing head, and then rotated relative to the housing head about an axis perpendicular to the axis of the tubular filter and to the axis of the first conduit.
