Scott Safety Supplied Air Respirator Pressure Demand with Escape Bottle: Gen Purpose, Hansen, 60 to 125 psi

3M partial SAR (supplied-air respirator) assemblies with an emergency escape cylinder provide a backup air supply in IDLH (immediately dangerous to life or health) environments. Partial assemblies include parts required to build a full system or to replace worn parts on existing systems. SARs provide safe breathable air in low oxygen environments or where air quality is compromised. An airline hose connects a worker's facepiece to a supplied-air compressor. The mobility of the worker is limited to the length of the airline, but the compressor offers an unlimited amount of air. System parts are compatible with components of the same brand and series.
