Abstract

A tangential filter for filtration of a fluid includes a support element, wherein, along a transverse plane perpendicular to the central axis of the support element a) the support element includes in its central portion only inner channels that do not share a common wall with its outer surface, the inner channels having a substantially equivalent hydraulic diameter, b) the support element includes peripheral channels, including at least first and second adjacent peripheral channels, each of the two channels sharing a common wall with the outer surface, c) the ratio of the hydraulic diameter of the first channel to the hydraulic diameter of the second channel is greater than or equal to 1.1, d) the number of peripheral first channels is greater than or equal to the number of peripheral second channels, e) the second channel has a hydraulic diameter substantially identical to the hydraulic diameter of the inner channels.
