Abstract: A maintenance-free respirator 10 that includes a mask harness and a mask body 11. The mask body 11 has at least one layer of filter media 56 and has a perimeter 32 that includes an upper segment 34. The upper segment 34 includes first and second concave segments 36, 38 that are located, respectively, on first and second sides of a central plane 40, when viewing the mask body from a top view. A maintenance-free respirator 10 of this configuration is comfortable to wear and can provide a snug fit to a wearer's face, particularly beneath each of the wearer's eyes, while at the same time having an ability to improve compatibility with various protective eyewear.

Abstract: A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member.

Abstract: The present invention relates to an exhaust apparatus for releasable or permanent connection to a personal protection respiratory device that defines a filtered air volume adjacent to the face of a wearer and comprises at least one exhalation valve. The exhaust apparatus comprising a powered blower in fluid connection with the at least one exhalation valve, the blower being operable to draw a portion of the wearer's exhaled breath through the at least one exhalation valve. Using such an exhaust apparatus for releasable connection to a personal protection respiratory device improves the comfort and overall experience for respirator wearers who use the respirator for intensive work, and/or for long periods of time, and/or in hot and humid environmental conditions by removing the heat and moisture build-up inside the respirator.
