摘要： A filter system 10 includes a pre-filter in a pre-filter zone 18 and a final filter in a final filter zone 22. The pre-filter is in the form of at least one inertial filter, e.g. an array 28 of axial flow cyclones 30. The final filter is in the form of a media filter 36 formed of a lofted bat of fibrous material which is of non-homogeneous structure through its depth. An upstream side is lofty, and a downstream side is of set structure. A contaminated fluid flow stream enters via an inlet 12. Contaminants are filtered out by the axial flow cyclones to be removed via a dust cover 32. Pre-filtered fluid flows via a chamber 20 through the media filter 36. After final filtration in the media filter it exits via a chamber 24 and an outlet 14.

摘要： A method of fabricating a filter element includes providing a lofted batt (10) of a fibrous material; and compressing and, simultaneously, deforming the batt (10), in a single operation to form a plurality of alternating ribs and valleys in the batt (10) to provide a one-piece article which constitutes the filter element. In a preferred form of the invention the method includes forming the ribs and valleys in a concentric annular pattern in the batt (10).

摘要： An apparatus (10) for manufacturing a filter element includes a first mould element (12) having a plurality of spaced parallel rib (14) defined thereon. A second mould element (18) is arranged in spaced alignment relative to the first mould element (12), the second mould element (18) carrying a plurality of spaced parallel ribs (22) displaceably thereon. A displacement means (24) which includes a cam arrangement (28) is mounted on the second mould element (18) for displacing the ribs (22) of the second mould element (18) sequentially towards the first mould element (12) such that, in use, when the ribs (22) of the second mould element (18) are displaced into meshing engagement with the ribs (14) of the first mould element (12), pleats or folds are formed in a sequential fashion in a batt of filter material arranged between the mould elements (12,18). The cam arrangement (28) comprises a plurality of cam members (32), a cam member (32) being associated with each rib (22) of the second mould element (18) and the cam members (32) having consecutively greater dwell angles to facilitate the sequential formation of the pleats or folds in the batt.
