MSA Ultralite II
MSA offers air masks in both low pressure (2216 psi) and high pressure (4500 psi) versions and can be customized with a variety of air cylinders for regular and extended-use applications. All MSA air masks comply with the requirements of NIOSH and MSHA. The Ultralite II complies with ANSI/NFPA- 1981, 1992. Air masks are pressure demand and designed to maintain a slight positive pressure of air inside the mask during inhalation and exhalation. This helps to prevent contaminants from seeping in around the facepiece even if there are small breaks in the face-to-facepiece seal.
