Title (EN) AIR FILTER MATERIAL, AIR FILTER PACK, AND AIR FILTER UNIT
(FR) MATÉRIAU DE FILTRE À AIR, BLOC DE FILTRE À AIR ET UNITÉ DE FILTRE À AIR
(JA) エアフィルタ濾材、エアフィルタパック及びエアフィルタユニット
Abstract:
(EN) This air filter material (10) comprises a first polytetrafluoroethylene (PTFE) porous membrane (1) and a second PTFE porous membrane (2). Fibers included in the first PTFE porous membrane (1) have an average fiber diameter of 0.24-0.45 μm, whereas fibers included in the second PTFE porous membrane (2) have an average fiber diameter of 0.04-0.23 μm. The air filter material (10) has a first main surface (11) and a second main surface (12), and the first PTFE porous membrane (1) and the second PTFE porous membrane (2) are disposed such that an airstream flowing from the first main surface (11) to the second main surface (12) passes through the first PTFE porous membrane (1) and the second PTFE porous membrane (2) in this order.
(FR) L'invention concerne un matériau de filtre à air (10) comprenant une première membrane poreuse en polytétrafluoroéthylène (PTFE) (1) et une seconde membrane poreuse en PTFE (2). Les fibres incluses dans la première membrane poreuse en PTFE (1) possèdent un diamètre moyen de fibre de 0,24 à 0,45 μm, alors que les fibres incluses dans la seconde membrane poreuse en PTFE (2) possèdent un diamètre moyen de fibre de 0,04 à 0,23 μm. Le matériau de filtre à air (10) possède une première surface principale (11) et une seconde surface principale (12), et la première membrane poreuse en PTFE (1) et la seconde membrane poreuse en PTFE (2) sont disposées de telle sorte qu'un courant d'air s'écoulant de la première surface principale (11) à la seconde surface principale (12) traverse la première membrane poreuse en PTFE (1) et la seconde membrane poreuse en PTFE (2) dans cet ordre.
(JA) エアフィルタ濾材(10)は、第1のPTFE多孔質膜(1)と第2のPTFE多孔質膜(2)とを含む。第1のPTFE多孔質膜(1)に含まれる繊維の平均繊維径が0.24~0.45μmであり、第2のPTFE多孔質膜(2)に含まれる繊維の平均繊維径が0.04~0.23μmであり、エアフィルタ濾材(10)が第1主面(11)と第2主面(12)とを有し、第1のPTFE多孔質膜(1)と第2のPTFE多孔質膜(12)とが、第1主面(11)から第2主面(12)へと通過する気流が第1のPTFE多孔質膜(1)、第2のPTFE多孔質(2)の順に通過するように配置されている。
