Filter system

A filter system 10 comprises a filter housing 12 having an inlet 18 and an outlet (20, Fig 2) and a lumen extending there-between. A seat 24 is associated with the housing between the inlet and the outlet and is adapted to retain a filter within the lumen. Preferably the seat is a circumferentially extending restriction formed in the housing and projecting radially inward. A filter element 14 comprising a shoulder 30, neck 32 and sock 28 may be retained by the seat and may be accessed via a removable end cap (34, Fig 2) provided on one end of the housing. Advantageously the filter system is for use in the dairy industry for filtering solid contaminants from milk and the filter element may be quickly and easily replaced thus minimising down-time of the filter system.
