A system for monitoring service life of a filter may include a respirator configured to be worn by an individual. The respirator may include a face mask and a filter housing that retains a filter within a filter chamber. A sensor assembly may be configured to monitor gas from the filter chamber. A respirator filter sampling port assembly is configured to adaptively connect the filter housing to the sensor assembly. The respirator filter sampling port assembly may include an adapter that removably secures to the filter housing, and fluidly couples the filter chamber of the filter housing to the sensor assembly.

System and method for monitoring a service life of a filter with a respirator filter sampling port assembly

A semi-disposable face mask has a shaped molded base composed of silicone and/or TPE and molded forming a face seal, a filter media and a support structure that houses the shaped molded base and filter media in fluid communication allowing airflow from an environment through the filter media to the face seal.

Half facepiece

A half facepiece respirator has a shaped support piece supporting and fixing the position of a particle or paper filter insert or outsert with either the support piece or the particle filter incorporating a face sealing component. Placed within the shaped support piece, a grille may be placed in the lower section of the shaped support piece. Additionally the half facepiece includes a head harness having a release mechanism.

A respirator comprising an outer mask in which is defined a main volume and an oronasal mask located within the outer mask and defining a secondary volume. Air for breathing enters the mask via a one-way valve and filter. Exhaled air exits the mask via an exhale conduit fitted with an exhale valve. A conduit is provided for the passage of air from the outer mask to the oronasal mask. The conduit is fitted with a one-way valve and a filter. The filter is such as to filter either particular or vapor challenges, or a mixture of these, as required.

Respirator having an integrated oronasal mask

A mounting assembly for a self-contained breathing apparatus (SCBA) includes a back plate defining a plurality of apertures therethrough arranged in first and second columns. The apertures in the columns are sized and spaced to receive corresponding first and second mounting straps woven therethrough that are configured to extend around webbing straps of a carrying jacket to fasten the back plate to the carrying jacket. The back plate includes a first press stud associated with the first column and a second press stud associated with the second column, which are configured to engage ends of the respective first and second mounting straps to releasably secure the mounting straps to the back plate. A tank securing strap on the back plate releasably fastens a supply tank to the back plate. A valve retaining mount on the back plate releasably secures an air supply valve for engagement with the supply tank.

Carrying plate for breathing apparatus

A mounting assembly for a self-contained breathing apparatus (SCBA) includes a back plate defining a plurality of apertures therein that are arranged in two columns extending down opposing side edges of the back plate. The apertures are sized and spaced to receive mounting straps that are configured to interface with webbing straps of a carrying jacket to fasten the back plate to the jacket. The mounting assembly also includes a tank securing strap with a quick release mechanism that is fastened to the back plate. The tank securing strap is configured to engage a supply tank to releasably fasten the tank to the back plate. The mounting assembly further includes a valve retaining mount disposed on the plate. The valve retaining mount is configured to releasably secure an air supply valve to the back plate for engagement with the supply tank.

A respirator includes an outer mask defining a first volume. An oronasal mask defines a second volume. The oronasal mask is positioned within the first volume. A primary filter is affixed to the outer mask and a secondary filter is positioned within the first volume such that the secondary filter filters air traveling from the first volume to the second volume. The secondary filter filters air traveling around a portion of the second volume. The filters are arranged to filter either particles or vapors, or a mixture of these, as required.
