MSA 460862 Half Mask Constant Flow Airline Respirator Assembly (Includes Black Medium Hycar Welder's Comfo 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.
The Welder’s Comfo Facepiece has an elbow that permits the breathing tube to be carried over the shoulder where it won’t interfere with a welder’s helmet. A web harness with a leather keeper holds the breathing tube in place.
