  • Publication number: 20230211905
    Abstract: A fluid distribution system includes single use distributor manifolds each having a distributor manifold inlet and a plurality of distributor manifold outlets in fluid communication with the distributor manifold inlet. A set of single use filler manifolds can be sequentially connected to a respective one of the outlets of a single use distributor manifold immediately upstream of the connection point of the set of single use filler manifolds. In embodiments, an upstream distributor manifold can be used to feed fluid to a set of intermediary distributor manifolds where the set of intermediary distributor manifolds corresponds to the number of outlets of the upstream distributor manifold.

  • Publication number: 20230211263
    Abstract: A fluid filtration system includes a single use filter removably mounted to a cabinet of a workstation. The upstream end of the single use filter is in fluid communication with a pump via a fluid supply conduit that includes a test junction. An integrity test device is supported by the cabinet and is in fluid communication with the upstream end of the single use filter via a test conduit fluidly connected to the single use filter via the test junction of the fluid supply conduit. The integrity test device adapted to be connected to a source of pressurized gas and to selectively direct a flow of pressurized gas through the test conduit and the single use filter to perform a test operation on the single use filter.

  • Publication number: 20230147354
    Abstract: A filter for filtering particulates from a fluid stream includes a filter element with a filter medium and a metallic debris sensor assembly. The metallic debris sensor assembly includes a core and a coil of electrically-conductive wire. The core has a first end, a second end, and an intermediate portion interposed between the first and second ends. The first end is disposed in spaced relationship with the second end such that a measurement area is disposed therebetween. The coil of electrically-conductive wire is wound around the intermediate portion of the core. The core is adapted to generate a magnetic field in the measurement area when an electrical current is passed through the coil. At least a portion of the filter medium of the filter element is disposed within the measurement area. The filter can be incorporated into a wear detection system and used in methods of monitoring.
