Lightweight, durable SCBA for many industrial Immediately Dangerous to Life or Health (IDLH) applications. The mask is designed to maintain a slight positive air pressure inside the facepiece during inhalation and exhalation. Positive pressure helps to prevent contaminants from seeping in and around the facepiece, even if small breaks in the facepiece seal should occur. Available in both low-pressure and high-pressure versions. Built from 6 major components: facepiece, carrier and harness assembly, cylinder, first stage regulator, mask-mounted regulator, and End-of-Service-Time-Indicator (EOSTI).
