    Abstract: The present invention provides a vacuum filter device including a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element that resiliently applies sealing pressure to the upper surface of the filter. The sealing element is maintained in place by a compression element formed of a ring that applies a desired compressive force to the sealing element. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place and under a compression seal. The invention also can provide for an alignment feature on the compression element that ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.

  • Publication number: 20140186496
    Abstract: A collapsible bag or compressible bottle container for accepting, holding, and filtering fluid. Fluid is filtered upon entry to the container or filtered upon egress. The filter media resides either in a removable cap, or in a second fluid-tight compartment attached to, and in fluid communication with, the container body. A one-way valve with unique one-time connection to a fluid source mitigates potential contamination from container overuse. A second collapsible layer is used in conjunction with the collapsible bag to accept compressed air that provides rigidity for the container body.

  • Patent number: 8757393
    Abstract: A replaceable filter has a filter housing with a cylindrical connecting end. A housing lid has a cylindrical counter connecting member matching the cylindrical connecting end. A filter closure system seal-tightly connects by form fit the cylindrical connecting end and the cylindrical counter connecting member when the connecting end is inserted or pushed onto the counter connecting member in an axial connecting direction and moved relative to the counter connecting member. An annular member is arranged coaxially relative to the connecting end and has a terminal edge area that is connected seal-tightly to the filter housing such that the annular member and the connecting end define a receptacle for the cylindrical counter connecting member. A sealing device is arranged in the receptacle and connected to the filter housing. The sealing device interacts with the counter connecting member.

  • Patent number: 8741139
    Abstract: The present device is a detachable core for use with a cylindrical filter cartridge. The core includes a wire frame including at least two vertical struts oriented along a longitudinal direction. The wire frame includes an upper ring and a lower ring mounted to the distal ends of the vertical struts and further includes an upper flange and a lower flange mounted to the upper and lower rings respectively, wherein the lower flange is detachably mounted to the lower ring. Preferably the lower ring includes a gap in the lower ring to enable resilient compression of the ring by squeezing the lower ring in a radial inward direction prior to engagement with the lower flange. Preferably the cartridge filter includes elastomeric end caps and the cooperating rings and flanges are non-circular such that the elastomeric end caps conforms to the non-circular shape of the upper and lower flanges.

  • Patent number: 8741137
    Abstract: Passing a fluid though a single filter module effectively removes at least two different types of impurities from the fluid. The fluid is directed through at least two different types of filtering media within the single module. The at least two different types of filtering media are separated from one another, within the single module, by a porous containment layer of the module; and, one of the at least two different type of filtering media forms a core of the module, which is surrounded by the porous containment layer.

  • Patent number: 8673149
    Abstract: A liquid filter assembly comprising a filter subassembly is inserted within an elongated tubular filter body, enclosed by a pair of end caps. The filter subassembly includes a plurality of filtration discs placed onto a tubular core and inner support member. A disc aperture is provided concentrically through each filtration disc. An outer filter support member and a central filter support member support each filtration disc. The outer filter support member engages with an interior of the elongated body and an end wall engages with the disc perimeter. The central filter support member engages with an exterior of the inner support member and an end wall engages with the peripheral edge about the filtration disc aperture. Fluid passes through the first end cap orifice, continuing through the inner support member, transferring flow through the filtration discs, returning through the inner support member, and exiting the opposite end cap orifice.
