MSA 460863 Full Face Constant Flow Airline Respirator Assembly (Includes Black Medium Hycar Ultravue Full Facepiece, Hose, Web Support Belt, Snap-Tite Aluminum Quick-Disconnect And High Pressure Control Valve) (1/EA)
Constant Flow Air-Line Respirators are designed to maintain a slight positive pressure of air inside the facepiece whether the wearer is inhaling or exhaling. This helps prevent contaminants from seeping in around the facepiece, even if there should be small breaks in the face-to-facepiece seal.
