Disposable filter unit with filter support means at both sides of the filter element

摘要

A disposable filter unit (1) comprises a two-part fluid-tight and pressure-resistant housing with funnel-shaped inlet and outlet connecting sleeves (3,20). Two filter supports (5,12) are fixed in a fluid-tight and form-locking manner within the housing, and the filter element fixed between the supports. The filter supports (5,12) are essentially circular grate-shaped plates including concentrically arranged coplanar circular webs (16) defining concentrically arranged circular gaps (19) therebetween and a centrally arranged baffle plate (17). The webs and plate are fixed at their back side, facing away from the filter element, with radially extending support webs (18).
