  • Patent number: 9943789
    Abstract: The present disclosure relates to modular filtration cassettes for filtering liquids including, for example, liquids used in semiconductor manufacturing. A filter housing may define a filter cavity comprising an upstream portion and a downstream portion. The filter may further comprise a filter element disposed in the filter cavity. The filter element may at least partially overlap the filter inlet on a first side of the filter element. The filter element may comprise a rectangular pleated filter with a set of pleats having a first set of pleat tips on an upstream side of the filter element and a second set of pleat tips on a downstream side of the pleated filter.

  • Patent number: 9802142
    Abstract: The present disclosure relates to purification cassettes that have reinforcing features. One embodiment relates to a purification cassette with tensions members. A purification system may include a removable cassette defining a media cavity. A set of tension members may span between a first sidewall and second sidewall. The set of tension members can divide the media cavity into a plurality of lanes.

  • Patent number: 9468872
    Abstract: The present disclosure relates to modular purification systems using removable purifier cassettes for purifying liquids including, for example, liquids used in semiconductor manufacturing. A purification system may include a removable purifier cassette having a purifier inlet port and a purifier outlet port, and a manifold assembly. The manifold assembly can include a plurality of connection systems to that provide manifold ports to provide fluid to/from the cassette. In some embodiments, the connection systems may use connection nuts that can provide 360 degrees of thread engagement with less than 360 degrees of rotation.

  • Publication number: 20150247595
    Abstract: This disclosure relates to connection systems for fluid connections. Even more particularly, some embodiments relate to fluid connections for use with semiconductor manufacturing fluids. The connection system uses a connection nut (110) that seals fluid fittings (112, 114) with less than 360 degrees of rotation of the connection nut by making use of multi-start threads in the nut (110). According to one embodiment, the connection nut creates at least 360 degrees of threaded engagement with less than 360 degrees of rotation. Embodiments further provide connection systems that can seal multiple ports simultaneously.

  • Publication number: 20140238922
    Abstract: The present disclosure relates to modular filtration systems using removable filter cassettes for filtering liquids including, for example, liquids used in semiconductor manufacturing. A filtration system may include a removable filter cassette having a filter inlet port and a filter outlet port, a filter cassette holder configured to receive and retain the filter cassette, and a main assembly. The main assembly can further comprise a filter inlet interface port configured to receive the filter inlet port, and a filter outlet interface port configured to receive the filter outlet port and can define flow paths to direct flow to and from the filter cassette. The filter cassette holder may be movably coupled to the main assembly such that the filter cassette is movable relative to the main assembly from an unmated position to a mated position.
