3M™ SA-Series Supplied Air Regulator Valves and Assemblies provide comfortable, cost effective respiratory protection for All-Day use. When used with approved 3M breathing tubes and 3M Versaflo (TM) headgear, can help regulate the air flow of a supplied air system. Supplied air respirators offer many features over traditional respiratory protection; fit testing only required for tight-fitting facepieces; and low maintenance. Complete systems include a supplied air hose, an air regulating valve, a breathing tube, and a helmet, hood, or other facepiece. 3M Supplied Air Respirators require a source of clean breathing air such as plant air systems or bottled air. This clean, breathable air can be delivered to hoods, helmets, full facepieces, half facepieces and loose-fitting facepieces.
