Abstract

PURPOSE: To obtain a filter low in initial pressure loss and reduced in pressure loss during use, in an air filter formed by folding a sheet like filter material in a zigzag pattern, by providing a narrow plane at right angles to an air stream to the fold part thereof on the windward side.
CONSTITUTION: An air filter 1 is equipped with a filter material 2 folded in a multi-stage zigzag state and a finger shaped spacers 3 arranged to the filtering surface of the filtering surface of the filter material 2 on the leeward side. In this case, the fold part 2 on the windward side form narrow planes 21 at right angles to an air stream and the fold parts 22 on the leeward side form edge shapes. In this filter, the wind pressure of the air stream passing the planes 21 and that of the air stream passing the side surfaces 23 of the ridge parts are well-balanced and, as a result, the warpage of each side surface 23 to the inside is prevented and the desired purpose can be achieved.
