Abstract: PROBLEM TO BE SOLVED: To miniaturize an air cleaner whole body with keeping pre-cleaner function.
SOLUTION: A filter element 2 is provided with a first cap 22 including a communication port 25 making a space part IS communicate to an outer part on both ends of a cylindrical main filter member 21 forming the space part IS in an inner circumference side, and a second cap 23 blocking the space part IS. A pre-filter member 101 is held in such a manner that the same can be detachably inserted from the communication port 25 to the space part IS. A case 3 is provided with a main body case 4 holding an oil element 2 attachably and detachably from an opening part OP with keeping an air gap ITS open from an outer circumference of the main filter 21, and a cover 5 opening and closing the opening part OP. A flow-in space (channel 37) of gas where the communication port 25 is positioned under a condition where the cover 5 is attached on the main body case 4, and a flow-out space (channel 35) of gas where the air gap is positioned are partitioned by a partition part (upper fitting part 36). A flow-in port 10 establishes communication between a flow-in space and the outer part, and a flow-out port 12 establishes communication between a flow-out space and the outer part.

Abstract: PROBLEM TO BE SOLVED: To prolong a lifetime of the whole of a filter by circulating a fluid from the outer periphery to the inner periphery both in a pre-filter element and in a water separation filter element.SOLUTION: A pre-filter element 101 and a water separation filter element 201 are housed in a housing 11 having an inlet 32 and an outlet 33 for a fluid each on an end side. The pre-filter element 101 has, in a filtration function part 131, a pre-filter medium 132 which blocks the filtration function part 131 on the outer periphery side and a circulation space 151 on the inner periphery side with a blocking wall 112 as a boundary and circulates a fluid from the outer periphery to the inner periphery facing a space connected to the inlet 32. The water separation filter element 201 is arranged in series with the pre-filter element 101 through a specified gap G between it and the pre-filter element 101, circulates the fluid passing through the pre-filter medium 132 and flowing in through the gap G from the outer periphery to the inner periphery of a water separation filter medium 231 to separate water and causes the fluid after separation of water to flow to the outlet through the circulation space 151 of the pre-filter element 101.

Abstract: PROBLEM TO BE SOLVED: To overcome the problem of imperfect sealing in a seal part or the problem of the assembly difficulty of a device even if a large error has occurred in the axial direction length of a filter element.SOLUTION: This filter device includes a basic configuration wherein the filter element 51 holding a filter material 53 by a pair of resinous end plates 52 (52a, 52b) is stored in a housing 101 having opened one face, and wherein an opening face 102 thereof is closed by a set plate 201. As a structure for securing sealability by sticking the filter element 51 to the set plate 201, in place of a structure to elastically deform the end plate 52a by directly pressing the end plate 52a against a recessed inner face 103 on one closed face side of the housing 101, an O-ring 57 is interposed between the recessed inner face 103 and the end face 55a of one end plate 52a in a state where the O-ring 57 is elastically deformed, and the other end plate 52b is closely pressed to the set plate 201 by its resilience.

Abstract: PROBLEM TO BE SOLVED: To make reusable a filter medium of an air filter by washing and to increase the capacity of the filter medium for capturing foreign matter.
SOLUTION: The filter medium 3 of the air filter for filtering air is formed from a nonwoven fabric in which metal-made fibers 10 are entangled irregularly with one another. As a result, the medium 3 can be cleaned by a washing liquid such as water and filtration can be performed not only on the surface of the medium 3 but also on the inside (in the depth) of the medium 3.
