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: 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.

Abstract: A portable cooling or respiratory blower system of the type carried by a user's body includes a housing having two air flow chambers. An impeller is rotatably disposed between the two air flow chambers and includes a base wall that places the two air flow chambers in non-fluidic communication when the impeller is rotated. A separate plurality of blades is provided on each side of the base wall.

Abstract: The present invention relates to a fan-forced positive pressure breathing apparatus commonly known as a Powered Air Purifying Respirators (PAPR) system, and specifically concerns the connecting of the breathing components of such equipment. The invention is a method and apparatus for rapid engagement of PAPR breathing components (such as air supply lines and filter elements to a blower housing). The invention also provides for indicating and/or monitoring whether the relative components have been aligned and coupled in sealed engagement.
