A filter element and a system for cleaning the filter element, including a plurality of layers of fibers arranged in substantially uniform orientation over at least a portion of their active length, along which portion at least, each of the fibers is disposed in close proximity to its adjacent fibers, and a body member constituting a backing surface for the fibers. The system further includes nozzle means for applying at least one fluid jet against the fibers; and means for applying a relative movement between the fiber layers and the fluid jet.

A filter element and a system for cleaning said filter element, comprising: a plurality of layers each containing a number of tensioned fibers having a known coefficient of friction therebetween and arranged in substantially uniform orientation over at least a portion of their active length, along which portion at least, each of said fibers is disposed in close proximity to its adjacent fibers; a body member with a surface of a given radius of curvature constituting a backing surface for said fibers; nozzle means having at least one outlet for applying a mixture of two fluids in the form of at least one pressurized fluid jet against the fibers; and means for applying relative movement between said fiber layers and said fluid jet, wherein the overall thickness h of the fiber layers is determined by the expression: [Figure] wherein: P is the fluid pressure of the jet in dynes per cm2; A is the width of the nozzle\s outlet in the direction of the fibers, in cm; B is the width of the nozzle\s outlet in the direction across the fibers, in cm: d1 is the specific weight of a first fluid in the fluid jet, in gram mass/cm3; 67 2 is the specific weight of a second, heavier fluid, which is mixed with the first fluid, in gram mass/cm3; n is the number of fibers in a cross-section of one cm2 of the fiber layers; T is the tensional load on a single fiber in dynes; m
