The KOKS EcoVac Combi vacuum/jetting truck can be used for suctioning, discharging and transporting fluid and hazardous substances, such as liquids, sludge, fats, oils, fuels and chemicals, but also for jetting and cleaning pipes, tanks and sewers at high pressure.


The powerful liquid ring vacuum pump allows large quantities of (fluid) substances to be processed in a short time and then transported in accordance with current ASME/ADR (CEOC) regulations. Thanks to the integrated high pressure pump, several types of cleaning can be performed on site with a single machine. Use of a standard transfer gearbox allows more accurate control of the water quantity by selecting the right gear. This results in a longer service life and less wear in the high pressure pump. Further advantages of using a transfer gearbox are reduced fuel consumption and a lower noise level. The user benefits from significant time savings and a huge reduction in cost.


The KOKS EcoVac Combi vacuum/jetting truck can be fitted with various option kits that are appropriate for your needs, for industrial applications and/or sewer cleaning work.
