Beschreibung
Zusammenfassung:	A supplied air respirator (10, 50) that includes a clean air source (16, 54), a facepiece (18, 18'), a hose (12, 52), and a hose adjustment mechanism (14, 34). The clean air source (16, 54) is designed to be carried by a user of the (10, 50), and the face piece (18, 18') is sized to fit at least over the user's nose and mouth. The hose (12) extends from the clean air source (16, 54) to the facepiece (18, 18'). The hose adjustment mechanism (14, 36) enables the hose length to be controlled so that slack is eliminated between the clean air source (16, 54) and the facepiece (18, 18'). The supplied air respirator (10, 50) is beneficial and that it reduces opportunities for the hose (12, 52) to become inadvertently caught on an article located in the work environment.
