UNICUS Series

UNICUS

BAUER UNICUS 4i / 4S all-in-one high-pressure breathing-air workstations merge compression, purification, four-cylinder storage, cascade control and a triple-station containment fill cabinet into a footprint of less than 1 m², delivering 13 – 26 SCFM at 5000 / 6000 / 7000 psi.

  • UNICUS 4i features a 15-inch HMI touch screen with solid-state Auto-Cascade™, reaches mission-ready status in five minutes and is available in a 7000 psi version—ideal for fire, marine and defense applications.

  • UNICUS 4S offers a PLC four-line text display with manual cascade and Snap-Pin™ tool-free doors plus a forward-tilt panel, making maintenance intuitive for petro-chem and industrial safety crews.
    Both models ship with a triple-station NFPA 1901:2016-certified cabinet and a B-SECURUS moisture-monitoring dryer, ensuring three ≤ 31″ SCBA / SCUBA cylinders are filled safely—even in extreme cold, sand or salt-spray environments.
