Sequential filter pack for fluids

A sequential filter pack for fluids comprising a set of superimposed disk-shaped rings with an annulus geometry, each of which has a plurality of circumferentially distributed grooves on its back and a plurality of projections on its front according to equal circular sectors until circumferentially covering the front of the ring;

• between these projections, each ring comprises radially arranged projections defining partitions (14) such that they give rise to alternating channels of increasing section (16) and channels of decreasing section (15), wherein each ring additionally comprises two (11, 13) sets of projections each of them formed by connecting arched ribs (11) forming a barrier of uniform height wherein the height of the set of arched ribs (13) closer to the center is greater than that of the outer arched ribs (11), and both (11, 13) sets of projections extend perimetrically such that an interconnecting circumferential channel (12) for interconnecting flow is defined between both sets of projections and wherein the heights of the partitions (14) are greater than the height of the remaining projections on the front
• wherein the inner edge of the rings comprises a bevel for separating the rings of the pack and all the sharp edges are rounded.
