Description
The Dräger PSS BG 4 Plus is a closed-circuit breathing apparatus engineered for long-duration rescue and firefighting missions where ambient air cannot be safely breathed. Its positive-pressure breathing system helps prevent hazardous substances from entering the breathing circuit, while the integrated CO₂ absorption system removes carbon dioxide from exhaled air for recirculation. Designed for up to four hours of operation, the unit includes the Sentinel II electronic monitoring system, which displays cylinder pressure and remaining operating time and provides warnings for low pressure, inactivity, and emergency situations. Its robust housing, reflective strips, ergonomic harness, and shoulder-positioned breathing hoses support durability, visibility, and wearer mobility. The Dräger PSS BG 4 Plus is suitable for underground mining, tunnel firefighting, industrial emergency response, and specialist rescue operations requiring reliable long-duration respiratory protection.
