Abstract:
1. 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.
