The separation apparatus has a housing 100 that is divided into a plurality of filtration chambers 102, each chamber having an elongate magnetic core 108 to generate a magnetic field to entrap the contaminant material as it flows through the filter body. A fluid communication passageway 603 is provided between the first and second chambers by short separators 105 and is positioned such that the fluid exposure to the magnetic fields is maximised, the flow, in use passing upwardly of the inlet chamber and downwardly of the outlet chamber. Magnets 107,108 are housed in tubes 301,300 and an automatic cleaning system is provided, the magnets being withdrawn/ inserted by piston 204 under the action of fluid supplied and withdrawn via ports 205,206 in response to contaminant build-up sensed by sensors 604,605. With the magnets withdrawn the contaminates are released from the tubes and may be purged. The inlet chamber may contain one or two magnet assemblies associated respectively two or four magnet assemblies in the outlet chamber. The apparatus is annular with a pair of inlet/outlet chamber combination located diametrically of the inlet 109/outletl 10 axis (fig 5), the piston assembly being housed in a central core 106 (figs 1,2) |
