Abstract: A respirator apparatus includes a respirator body, a filter cartridge receiver integral with and extending from the respirator body, and a filter cartridge. The filter cartridge includes a nozzle element being integral with the filter cartridge. The respirator body and filter cartridge are configured to be fluidically coupled through sleeve-fit engagement between the filter cartridge receiver and nozzle element and the filter cartridge receiver and nozzle element define an airflow channel.

Abstract: A filtering device 10 that includes a housing 12 having a plurality of subsections 32, 34, and 36 where each subsection is adapted to receive a filter element 26, 28, and 30. An inlet 18 is disposed at a first location on the housing 12, and an upstream air distribution system is placed in fluid communication with the inlet 18 and with each of the subsections 32, 34, and 36. A downstream air distribution system is located in fluid communication with each subsection 32, 34, and 36, and an outlet 20 in fluid communication with the downstream air distribution system. The upstream and downstream air distribution systems are constructed to cause the same airflow velocity through each subsection. Using such a construction, overall product service life may be increased while minimizing pressure resistance of the total filter.

Abstract: A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.
