DYNAJETting with a system: the powerful Dynabox 350/12 V hot-water unit, offering a working pressure of up to 350 bar (5,075 PSI), is the ideal complement for all DYNAJET trollies. Simply connect on the high-pressure side between the high-pressure cleaner and the cleaning tool and, with high-pressure hot water of up to 110 °C, you’ll already be achieving results which aren’t possible with conventional cold-water systems. The other special features of the Dynabox 350/12 V are, of course, its light weight, small dimen-sions and its easy-loading and easy-transportation characteristics. What is more, the Dynabox 350/12 V works with a 12 V supply voltage. This means that no 230 V power cable is necessary, because the Dynabox 350/12 V can be easily connected to and operated via the combustion-driven DYNAJET trollies which are equipped with sockets as standard.
