The new AirHawk II Air Mask is built upon MSA's established AirHawk MMR Air Mask and is a lightweight, durable, and economical SCBA for many industrial IDLH (immediately dangerous to life or health) applications. This SCBA fits any budget by keeping its lower-cost options while offering many new choices not offered with any other industrial air mask. In addition, the AirHawk II Air Mask is available in both low-pressure and high-pressure versions.
MSA's AirHawk II Air Mask is a pressure-demand apparatus 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 face-to-facepiece seal should occur. The AirHawk II Air Mask is built from six major components: facepiece, carrier and harness assembly, cylinder, first-stage regulator, mask-mounted regulator, and End-of-Service-Time-Indicator (EOSTI).
