Product Details?

• The new Air Hawk II Air Mask is built upon MSA?s established Air Hawk 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 Air Hawk II Air Mask is available in both low-pressure and high-pressure versions.
• MSA?s Air Hawk II Air Mask is a pressure-demand apparatus designed to maintain a slight positive air pressure inside the face piece during inhalation and exhalation.
• Positive pressure helps to prevent contaminants from seeping in and around the face piece, even if small breaks in the face-to face piece seal should occur.
• The Air Hawk II Air Mask is built from six major components: face piece, carrier and harness assembly, cylinder, first-stage regulator, mask-mounted regulator, and End-of-Service-Time-Indicator (EOSTI).
