Abstract: A magnetic filter 10 comprises a magnetic rod sleeve 24 and a magnetic rod guide 28 disposed at an opening of the magnetic rod sleeve 24 and a magnetic rod 38 for inserting through the magnetic rod guide 28 and into the magnet sleeve 24; the magnetic rod guide 28 comprising a through aperture 34 for receiving the magnetic rod 38 and a seal 52 inside the through aperture 34 for providing a water-tight seal between the magnetic rod guide 28 and magnetic rod 38, and the magnetic rod 38 comprising an air conduit 54 between an interior of the magnetic rod sleeve 24 and an exterior of the filter 10 for allowing air within the sleeve 24 to be displaced as the magnetic rod 38 is inserted into the sleeve 24.

Abstract: A magnetic rod guide for a filter is provided that includes a base for attachment to part of a filter, a through aperture through which a magnetic rod can move, and resilient engagement device. The resilient engagement device includes one or more resilient latches for holding the magnetic rod in one or more fixed positions relative to the guide. Each resilient latch is adapted to allow movement of the magnetic rod through the through aperture in either direction, for insertion into the flier or withdrawal from the filter into one of the fixed positions.

Abstract: A magnetic rod guide for a filter comprises a base for attachment to part of a filter, a through aperture through which a magnetic rod can move, and resilient engagement means including at least one resilient latch for holding the magnetic rod in one or more fixed positions relative to the guide, the or each resilient latch further being adapted to allow movement of a magnetic rod through the through aperture in either direction, for insertion into the filter or withdrawal from the filter into one of the fixed positions.
