ABSTRACT:
A filter element for removal of particulate matter from a flow of gas has a plurality of elongate fluid flow passages each defined by porous gas filtration material and arranged as an integral assembly in which the passage lie side-by-side to extend parallel with one another between end regions of the filter element, at least one end of each elongate passage being sealed to prevent free flow of gas to or from the passages, the elongate passages being defined by self-supporting walls of porous gas filtration material and the filter element being substantially rigid or semi-rigid so as to attenuate transverse vibration by no more than 70% between an end of the filter element and a position mid-way between its ends.
