    Abstract: Air filtering devices are disclosed that contain a first filter cartridge having a cartridge inlet and a cartridge outlet and a curved filter bed having a concave surface disposed such that air to be filtered passes through the inlet, the curved filter bed, and the outlet. The air filtering devices also contain a blower assembly having a blower inlet in fluid communication with the cartridge outlet and a blower outlet, the blower assembly includes a motor proximate to the concave surface of the curved filter bed. The motor has a rotational axis such that the rotational axis is adjacent to the center of curvature of the curved filter bed. The air filtering device may be used in powered air purifying respirators.

    Abstract: A respirator 10 that includes a mask body 14, a filter cartridge receptacle 15, and a filter cartridge 12. The filter cartridge 12 has a side 30 that is capable of being plugged into the receptacle 15. The filter cartridge 15 can be inserted into the proper position within the receptacle 15 while the mask body 14 is being donned. The securement can be achieved without having the user visibly witness the actual engagement. An audible click or other indication can be provided so that the user knows that proper engagement has been achieved. The engagement may exhibit little spacing between the filter cartridge 12 and the mask body 14, thereby improving viewer visibility and making the inventive respirator 10 more comfortable to wear.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。
