DYNAJET
500mg HELI
The DYNAJET 500mg HELI is a transportable high-pressure water jetting system delivering up to 500 bar. Combining a reliable Honda petrol engine, DYNAJET's HELI technology and a compact trolley design, it provides powerful independent operation wherever high-pressure performance is required.
Working pressure should match the task. Surface preparation and general maintenance typically use 150 to 500 bar, while industrial coating removal and concrete work require higher pressure.
