The SCBA-G is a modular combination SCBA/PAPR designed to provide long-duration breathing protection to emergency responders. Utilizing proven, tested technology, the SCBA-G is ideal for missions requiring long entry/egress or involving unknown elements that may require more or less protection. Without exposure to the environment, the user chooses the level of protection—compressed or filtered air. Featuring the Draeger AirBoss PSS100 SCBA and C420 PAPR technology, the SCBA-G’s modular design provides the option of a standard, standalone SCBA or CBA (Combination Breathing Apparatus).
