摘要： A respirator includes a mask body. The respirator further includes a harness including one or more elastic straps. Each of the one or more elastic straps is joined to the mask body on opposing sides thereof. Each of the one or more elastic straps includes at least one first color scheme and at least one second color scheme. The at least one first color scheme is visibly different from the at least one second color scheme. Each of the one or more elastic straps includes at least about 0.5% to about 99.9% of an elastomeric polyolefin by weight.

摘要： A configurable exhale system for a respirator has a first valve assembly disposed within a chamber which is configured to prevent air from flowing through the first valve assembly when an air pressure differential between an upstream side and a downstream side of the first valve assembly is below a first opening pressure. A second valve assembly is disposed within the chamber in fluid communication with the first valve assembly which is configured to prevent air from flowing through the second valve assembly when an air pressure differential between an upstream side and a downstream side of the second valve assembly is below a second opening pressure, which is greater than the first opening pressure. A bypass opening is positioned adjacent the second valve assembly configured to enable air to bypass the second valve assembly with a bypass member positioned adjacent to the bypass opening. The bypass member is movable between two positions with the bypass member blocking the bypass opening in a first position and the bypass member does not block the bypass opening in a second position.

摘要： A breathing apparatus according to embodiments of the invention includes a facemask portion sized to cover a lower portion of a wearer's face. The facemask portion includes a flow chamber. The flow chamber includes a first opening disposed near a first end of the flow chamber, a second opening disposed near a second end of the flow chamber, and a serpentine passage disposed between the first opening and the second opening. At least one light emitting diode configured to emit light having a peak wavelength in the ultraviolet range is disposed in the serpentine passage. The at least one light emitting diode is disposed off center relative to a centerline oriented along a direction of air flow through the serpentine passage.

摘要： An oxygen system supplies either 100% oxygen to a demand valve in the a mask or pulses of oxygen to the mask. Switching is automatic during a parachute descent. The system includes a valve manifold that is responsive to ambient pressure such that at low pressures it is configured to deliver gas from either an oxygen cylinder or an aircraft supply line to the mask demand valve and at higher pressures it is configured to deliver gas from the cylinder to a pulse gas delivery system. The mask also includes an inhalation valve that is closed if oxygen is supplied to the demand valve. Otherwise, the inhalation valve opens to allow ambient air to be drawn in and the pulse gas delivery system delivers a pulse of oxygen in response to the onset of inhalation.

摘要： One or more embodiments of a respirator that includes a polymeric netting is disclosed. The respirator can include a mask body including a perimeter, a harness attached to the mask body, and a face seal disposed adjacent at least a portion of the perimeter of the mask body. In one or more embodiments, the face seal includes a polymeric netting including polymeric ribbons and polymeric strands, where each of the polymeric ribbons and strands having a length, width, and height, where the length is the longest dimension, the width is the shortest dimension, and the height is the dimension transverse to the length and the width. The polymeric ribbons have a height-to-width aspect ratio of at least 5 to 1, a major surface that is intermittently bonded to only one polymeric strand, and a height that is at least two times greater than a height of the one polymeric strand.
