Title:
FLUID FILTER
Document Type and Number:
WIPO Patent Application WO/2004/026439
Kind Code:
A1
Abstract:
A fluid filter (1) is a rectangular parallelepiped-shaped board-like body constructed from an air-permeable ceramic porous body with a three-dimensional mesh-like skeleton structure. The board-like body has a large number of empty chambers (2) that are through-holes penetrating from one side-face (1a) to the other side-face (1b) parallel to the one side face. The through-holes are round holes and are arranged so as to be in a stagger form at the side faces (1a, 1b). Providing the empty chambers (2) reduces pressure loss and enables the fluid filter to remove dust from a gas for a long period at reduced pressure loss.
