Breathing Air

ALL IN ONES

BAUER All-In-One Breathing Air Workstations (UNICUS® series) represent the pinnacle of fully integrated, space-efficient SCBA recharging technology.

Combines compressor block, purification system, ASME cascade storage bottles, and SCBA containment fill station inside a single sound-attenuated cabinet.

Features an independently tested, blast-resistant SCBA containment fill station (CFS 5.5®) engineered to protect operators during cylinder recharging.

Advanced models (UNICUS® 4i) include automated cascade fill control, 15" touch-screen HMI, and RFID cylinder tag identification for seamless record-keeping.

Fully enclosed acoustic cabinet dampens operational noise to levels under 72–79 dBA, allowing installation directly inside active apparatus bays.
