  • Patent number: 10465941
    Abstract: The invention pertains to a filter retaining assembly which is rigid and self-supportive without requiring any additional structural reinforcement. The design maximizes the filter surface to be used for air filtration and increases the filtration efficiency. The invention is also designed to minimize the filter assembly size to fit into the valuable space when the air handling unit physical dimension is constrained. The invention uses integral construction methods to save assembly time and labor by eliminating the need of using alignment holes and fastening each individual frame to construct a conventional filter retaining assembly. The proposed method maintains flexibility of scaling to any filter size and quantity.

  • Publication number: 20140224748
    Abstract: Provided are filtration devices for purifying fluids from bioprocess applications and processes for using the same. The fluid filter elements or cells and fluid filter assemblies or capsules minimize upstream and residual volumes by the use of substantially flat interior surfaces. Desired pressure ratings are also met without the use of external equipment. Such capsules and assemblies can be disposable. The cells and capsules are in particular suitable for intermediate filtration volumes (150-2500 cm2 effective filtration area (EFA)) of biopharmaceutical processes. One or more of the following features are also provided by these cells and capsules: ergonomic connections, stand alone device with desired pressure rating, offer a small footprint when running in series or parallel, ability to monitor fluid level during operation, provide various EFA sizes to allow for use with minimal fluid volumes, and offer an integral seal between clean and dirty process fluid streams.
