  • 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: 8658044
    Abstract: A stormwater filter cartridge includes a housing with internal filter medium disposed along a flow path between a water inlet and a filtered water outlet. A solid wall float tube in a drainage space has an open lower end and open upper end and is movable between a lowered position and a raised position. As the housing fills, water level in the housing rises to cause the solid wall float tube to move to the raised position and a negative pressure draws fluid through the filter medium. As water level outside the filter cartridge drops, air enters the housing and causes the solid wall float tube to drop to the lowered position, and filtered water in a fluid reservoir backflows through the filter medium while air enters the housing by passing upward through the solid wall float tube so as to enhance rate of backflow.

  • Patent number: 8640884
    Abstract: Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. For some embodiments, the ribbon may comprise a composite having first and second layers. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Many, most, or substantially all of the spaces may be substantially free of structure. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.
