Patent number: 11014113Abstract: A filter for industrial coating filtration systems. The filter has a housing made up of a peripheral wall extending around the periphery. The housing is preferably made of a suitably rigid material. A preferably rigid support backing is mounted within the housing. The support backing has a planar configuration with openings formed through it so that gas can flow through without substantial resistance. The preferably planar sheet of which the support backing is made is pleated. The pleated support backing defines a series of panels, each of which is angled to a next adjacent panel. Filtration media is mounted to the support backing, end caps are attached to the ends of the support backing to maintain the pleated configuration, and the assembly is inserted into the housing, which can have end flaps to seal using tape or adhesive.Type: GrantFiled: March 3, 2020Date of Patent: May 25, 2021Assignee: Columbus Industries, Inc.Inventors: Mounir B. H. Slama, James E. Large, Daniel J. Baizel, Michael K. Haufe

Patent number: 10213722Abstract: A rigid support is disposed in a filtration media element. A first gas-permeable filtration media layer is disposed in an overlapping orientation with a second gas-permeable filtration media layer. The first and second layers define a void in which the support is disposed. The first layer is attached to the second layer near opposing edges of the first and second layers and at an attachment termination point substantially centrally located on the filtration media element. The filtration media element has a first media end and an opposite, second media end. The support has a first support portion that extends from the first media end toward the attachment termination point. The support has second and third support portions that extend from the first support portion toward the second media end with a gap between the second and third support portions in which the attachment termination point is disposed.Type: GrantFiled: December 4, 2015Date of Patent: February 26, 2019Assignee: Columbus Industries, Inc.Inventors: Michael K. Haufe, James E. Large

Publication number: 20040163370Abstract: A filter media kit assembly and method of mounting and replacing the spent filter media wherein a filter media component and independent retaining and supporting members are used cooperatively to removably mount the filter media within a respective one of a plurality of rigid frames comprising a multiple array of filters forming a grid arrangement. A bag-type filter, having a common central opening and at least two pocket-like areas, is removably mounted within the opening of each frame by entrapping an outer edge portion of the filter media in a press-fit relationship against the inner edges of the sides of the rigid frame forming a central opening. A support rod is provided for insertion across the opening of the frame prior to mounting of the multiple pocket bag filter in the frame and to facilitate and supplement supporting the bag filter in the frame against the air flow applied to the filter grid array during normal operation.Type: ApplicationFiled: February 2, 2004Publication date: August 26, 2004Inventors: Michael K.
