摘要： Conformal filter cartridges, filtering apparatus using the conformal filter cartridges, and methods of manufacturing the conformal filter cartridges are disclosed. The conformal filter cartridges may include a bed of filter material between a pair of support plates, wherein the major surfaces of the support plates facing the bed of filter material are each curved about at least one axis. The curvature imparted by the support plates provides the conformal configuration to the filter cartridge. The bed of filter material may be loose particulate filter material that may be retained under residual compression between the support plates within the filter cartridge.

摘要： A filtering device 10, 10′ that has a fluid inlet 12, a plenum 14, first and second filter layers 16 and 18, first and second fluid outlets 20 and 22, and a housing 24. The plenum 14 receives air that passes through the fluid inlet 12, and the first and second filter layers 16 and 18 are located on opposing sides of the plenum 14. The first and second fluid outlets 20 and 22 are located downstream to the first and second filter layers 16 and 18, respectively, on a side of each filter layer 16, 18 opposite the plenum 14. The housing 12 supports the first and second filter layers 16, 18 on opposing sides of the plenum 14. Very good distribution of fluid through the device 10 may be achieved because the plenum 14 and the filtering layers 16, 18 maintain their original relative positioning throughout use. Complex shapes can be produced, which enable the filtering device to accommodate devices of various configurations. Thicker filter media beds may be used on each side of the plenum to improve filtration performance and service life.

摘要： A method of making a filter cartridge, which method includes: (a) providing first and second filter media layers that each contain active particulate that is bonded together and that each comprise a perimeter; (b) stacking the filter media layers in a spaced apart relationship; and (c) securing a roll based housing sidewall to at least a portion of the perimeter of each filter media layer. The resulting filter cartridge is light in weight but has increased volume that provides an improved service life. The cartridge has a very good service life to weight ratio.

摘要： A filter canister assembly utilizes a sealant deflector to seal a particulate filter to the canister wall, even after the canister is sealed. The canister housing has a wall and an aperture with a particulate filter disposed therein. The particulate filter has an edge adjacent the wall, and is designed for removing particles of contaminants from a fluid, such as air, passed through the canister. A sealant deflector includes a plurality of vanes standing proud of a support substrate, and is situated between the aperture and the particulate filter and forms a permanent part of the canister assembly. The sealant deflector deflects a sealant in liquid state toward the wall to form a seal between the edge and the wall when the sealant is deposited on the sealant deflector while spinning. This deposits a sealant ring sealing the wall to the edge. The sealant deflector is self-centered under the aperture, by a bow-tie shaped structure of four arms extending outward radially from the sealant deflector connected in pairs by curved braces.
摘要翻译：过滤罐组件利用密封剂偏转器将微粒过滤器密封到罐壁上，甚至在罐被密封之后。罐壳体具有壁和孔，其中布置有微粒过滤器。颗粒过滤器具有邻近壁的边缘，并且被设计用于从通过罐的流体（例如空气）中去除污染物颗粒。密封剂偏转器包括多个叶片，其支撑着支撑基板，并且位于孔和微粒过滤器之间并形成罐组件的永久部分。当密封剂在旋转时将密封剂沉积在密封剂偏转器上时，密封剂偏转器将液体状态的密封剂朝向壁偏转以在边缘和壁之间形成密封。这将一个密封环沉积在边缘上。密封剂偏转器通过由弯曲的支架成对连接的密封剂偏转器的径向向外延伸的四个臂的弓形结构而在孔下方自对中。

摘要： An improved respirator filter assembly includes an integral fit seal check mechanism easily controlled by the user. Upon release, the seal check mechanism permits free airflow through the filter assembly. The seal check mechanism includes an air passageway having a sealing rim and a blocking member which is selectively movable between engaged and disengaged positions relative to the sealing rim. A spring element is disposed to releasably maintain the blocking member in the disengaged position during filter assembly operation, wherein a user may actuate the blocking member against the bias of the spring element to move the blocking member into the engaged position to substantially prevent entry of air into the air passageway during seal checking.
