The BAUER VERTICUS PLUS combines the same package amenities found in the BAUER VERTICUS high-pressure breathing air compressor system with a free-standing and multi-functional fill station module. It includes two bank dual-function cascade controls, an integral air storage rack with two UN code air storage cylinders, and a 3-way selector valve to choose air from the compressor or onboard air storage system. You can install the two modules together as an all-in-one configuration or separately. It depends on the installation site specifics.
