UNICUS® 4S

4- AND 5-STAGE ALL-IN-ONE HIGH-PRESSURE BREATHING AIR COMPRESSOR

A modern upgrade with the simplicity of analog controls; Aesthetically pleasing yet robust design found only in the UNICUS^® 4S All-In-One platform. The system is available in either 5000 or 6000 PSIG with discharge capacities ranging from 13 scfm charge rate to 26 scfm charge rate. Unsurpassed maintenance accessibility abounds as we have provided all access doors with snap-pin technology – pull the pin and lift the door; no hand tools are required. Should you require access to the back of the operations panel, no problem; we have your back, and the panel tilts forward. All requisite panels are equipped with sound-attenuated material. Along with the piping, an integral rack built to accommodate four (4) storage cylinders is standard. Additionally, we provide two (2) ASME-coded air storage cylinders as a part of the standard scope of supply. If you want to dress your unit up in concert with the Fire Department theme, ask about our Fire Edition package. When your department needs the best All-In-One compressor system on the market today and backed by our global network of service partners, look to BAUER.
