UNICUS 4S | Bauer Compressors

The UNICUS^® 4S is available in either 5000 or 6000 psig with discharge capacities ranging from a 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: the panel tilts forward. All requisite panels are equipped with sound attenuated material. An integral rack was built to accommodate four (4) storage cylinders as standard, along with the piping. 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, backed by a global network of service partners, look to BAUER.
