Bracket for respiratory sensing device

Welding attachment for a respirator

A dual-molded silicone-polyamide composite article including a first molded piece that comprises a blend of polyamide and an ethylene-vinyl alcohol copolymer and a second molded piece that comprises a thermoset, hydrosilylation-cure silicone polymer. A portion of a surface of the second molded piece is autogenously bonded to a portion of a surface of the first molded piece.

Dual-molded polyamide-silicone composite article and methods of making

There is provided a respiratory protection device comprising a mask body defining a breathable air zone for a wearer and having a front cover; an exhale valve in fluid communication with the breathable air zone; and a seal check mechanism disposed in the front cover, where the seal check mechanism comprises a button associated with a flap such that, when actuated, the flap biases the exhale valve in a closed position. There is provided in some embodiments a plane of the button intersecting with a plane of the exhale valve. There is also provided in some embodiments the button and the plunger being a monolithic part.

A respirator including a facepiece with a transparent lens that is recessed radially-inwardly relative to an opaque frame of an opaque chassis of the facepiece. The respirator is configured to receive a vision-protecting module.

Respirator configured to accept vision-protecting module

The present description provides components that allow a respiratory protection device to be secured in a position of use by attachment with a headwear suspension. In some exemplary embodiments, a harness adapter is positioned along a strap of a headwear suspension and includes a harness attachment element that may releasably attach to a strap component of a respiratory harness assembly.

Headwear suspension attachment element

The present disclosure provides a respiratory protection device that includes a valve assembly operable between an open configuration and a closed configuration. In some exemplary embodiments, the respiratory protection device includes a mask body having a first air chamber, a second air chamber, and a breathable air zone. A valve assembly is operable to a closed configuration to prevent airflow from the first and second air chambers into the breathable air zone.

Multiple chamber respirator sealing devices and methods

A buckle assembly for selectively connecting first and second straps of a personal protective device. The buckle assembly includes a receiver member and a latch member configured for coupling to a respective one of the straps. The receiver member defines a slot and provides a release arm. The latch member includes a latch tab pivotally connected to a base. In a latched state in which the latch member is disposed within the slot and a latch face is engaged with a capture surface. The release arm disposed over a portion of the latch tab. The latch face can be disengaged from the capture surface in response to an actuation force applied to the release arm. In some embodiments, the receiver member and the latch member incorporate various, complimentary guide surfaces that promote easy insertion of the latch member into the receiver member.

Respiratory assemblies are disclosed that include first and second respiratory components and a latching mechanism. The latching mechanism is capable of engaging at least one retaining feature of a respiratory component, thereby impeding disengagement of the first respiratory component from the second respiratory component. Upon application of force to the actuator, the at least one latch is capable of disengaging from the retaining feature, thereby allowing disengagement of the first respiratory component from the second respiratory component. Respiratory components including or adapted to work with such latching mechanisms are also disclosed.

Respiratory assembly including latching mechanism

A radial flow filtration system includes a housing and one or more generally cylindrical filter cartridges including a filter cartridge shell and a filter section. The filter cartridge is removable with respect to the housing and the filter section in removable with respect to the filter cartridge shell.
