摘要： The present invention provides filter units that, when joined together, allow joining portions thereof to be fixed together satisfactorily and can prevent air from leaking at the joining portions. A filter unit includes a filter medium that has been pleated and a frame that supports the circumference of the filter medium. The frame has a protruding part on at least one face selected from an upper face and a lower face thereof, with the protruding part being formed by allowing a part of the at least one face to protrude. The upper face is a surface of the frame that faces the upstream side relative to the flow of air that passes through the filter medium, and the lower face is a surface of the frame that faces the downstream side relative to the flow of air.

摘要： Provided is a filter unit in which an increase in pressure loss is suppressed despite the use of an injection-molded resin as a frame. This filter unit includes a pleated filter medium 1 and a frame 2 for supporting the filter medium 1. The frame 2 has inner and outer peripheries, each of which is rectangular in shape when viewed along an air flow path through the filter medium 1. In this filter unit, the filter medium 1 is fixed to the frame 2 with a peripheral portion of the filter medium 1 being embedded inside the frame 2. The pleated filter medium 1 has a value DIP of 0.25 or less. This value DIP is obtained by dividing the distance D between adjacent ridges of the pleats of the filter medium 1 by the height P of the pleats. The distance D has a minimum value d of at least 1 mm. The frame 2 has a length La longer than a length Lm. The length La is a length of the frame 2 measured in the direction in which the ridges of the filter medium 1 are arranged, and the length Lm is a maximum length of the frame 2 measured in the direction in which the ridges of the filter medium 1 extend. The frame 2 is a resin member containing 5 to 30% by weight of glass fiber. The frame 2 can be formed by injection molding.

摘要： A filtering medium for air filters wherein its surface conditions have been improved, whereby the porous PTFE membrane is not damaged even after pleating, thus appropriately meeting needs for clean space in clean rooms. The filtering medium comprises a porous polytetrafluoroethylene membrane (2) and an air-permeable supporting member (1) which are laminated such that at least one of exposed surfaces comprises a surface of the air-permeable supporting member (1) having a maximum frictional resistance of 25 gf or less. This filtering medium can be obtained by, for example, press bonding the air-permeable supporting member (1) to the porous membrane (2) under heating and then pressing the surface of the air-permeable supporting member (1) to a silicone roll (4) for smoothing.
