Abstract: A separator arrangement including a tubular member extending along a longitudinal axis and a toroidal blade arrangement disposed within the tubular member in a fixed position. The toroidal blade arrangement can include a plurality of blade members, each being looped from a first end to a second end with a radially distal portion located between the first and second ends to define a radially bounded passageway extending along a second axis disposed at an oblique angle to the longitudinal axis. In one aspect, each of the blade members is looped such that an inner side surface presents both a leading face and a trailing face.

Abstract: The technology disclosed herein relates to a vent assembly having a vent housing that defines a first airflow pathway, a second airflow pathway, and a third airflow pathway. The first airflow pathway is configured for fluid communication with an interior of an enclosure. The second airflow pathway is configured for fluid communication with the external environment, and the third airflow pathway extends between the first airflow pathway and the second airflow pathway. A membrane is coupled to the vent housing such that the second airflow pathway and the third airflow pathway are in communication through the membrane. Coalescing filter media is disposed within the vent housing such that the third airflow pathway and the first airflow pathway are in communication through the coalescing filter media. The vent assembly defines a spacing region between the coalescing media and the membrane.

Abstract: Porous ePTFE articles coated with a hydrophilic coating are provided. The coating may be modified by covalent modifications to the PVOH coating. Covalent modifications may include small molecule grafting, polymer grafting to or from the PVOH backbone, crosslinking of the polymer via thermal or photochemistry, and the like, and combinations thereof. A second polymer coating may be applied onto the PVOH coating. The second polymer may be added, for example, by using a saturation coating technique such as dip coating or spray coating to saturate a PVOH coated ePTFE substrate with a second polymer carried by a fluid. Application of the second polymer may form a second conformal coating over the first PVOH coating.

Abstract: Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.
