  • Publication number: 20240131462
    Abstract: An air-cleaning filter includes a non-woven fabric for dust collection and a non-woven fabric for deodorization having activated carbon particles combined therewith. By adjusting the particle diameter and content of the activated carbon particles and laminating with a non-woven fabric coated with an absorber for other gases, a dust collecting function and a deodorizing function can be imparted at the same time while also creating a structure with a low differential pressure.

  • Publication number: 20240033674
    Abstract: The tube-shaped pleated filter member may comprise: a filter body having a tube shape such that a filter medium is pleated and is wound; and a support unit. The filter body may comprise outer pleated portions corresponding to the outside of the tube shape, and inner pleated portions corresponding to the inside of the tube shape. An inner virtual line connecting corners of the inner pleated portions may have the shape in which a unit wave shape recessed in the outward direction is repeated. Assuming, that the thickness at a part having the maximum distance between the inner virtual line and the outer virtual line is a first thickness (T1), the first thickness (T1) may have a range defined by [equation 1] with regard to the diameter (D) of the outer virtual line. D/15?T1?D/6.

  • Patent number: 11731071
    Abstract: A filter assembly including: a first filter medium that is bent so that high-point portions and low-point portions defined based on a vertical plane with respect to a first direction are alternately and repeatedly formed in a second direction perpendicular to the first direction; a first filter frame configured to accommodate the first filter medium and to fix an edge side of the first filter medium; a second filter medium that is bent so that the low-point portions and the high-point portions based on the vertical plane with respect to the first direction are alternately and repeatedly formed in the second direction; and a second filter frame configured to accommodate the second filter medium and to fix an edge side of the second filter medium, wherein at least a portion of the high-point portions repeatedly formed in the first filter medium have different heights from those of the other high-point portions, and at least a portion of the low-point portions repeatedly formed in the second filter medium have d

  • Publication number: 20210339177
    Abstract: The present invention relates to a dust collecting filter and a process for manufacturing the same. Specifically, according to an embodiment of the present invention, the filter medium contained in a dust collecting filter comprises a first nonwoven fabric layer, a porous layer, a second nonwoven fabric layer, and a polypropylene melt-blown layer sequentially laminated, wherein the melt-blown layer has a melt index and a basis weight in specific ranges, and the first nonwoven fabric layer and the second nonwoven fabric layer have a sum of the basis weights in a certain range, whereby it is possible to enhance the sustainability, processability, and bendability of the filter medium, enhance the workability at high temperatures and adhesion, and further enhance the durability and life span characteristics of the filter.
