The configurable HD 9/18-4 ST, with an output of 180 bar and 900 l/h, is Kärcher's all-round solution in the field of cold water machines for operation with a lance.
Although many of the equipment features of our cold water high-pressure cleaner HD 9/18-4 ST are freely configurable, with a working pressure of 180 bar and a delivery of at least 900 l/h, it deserves the title "all-rounder" for its versatile application options, from industry to agriculture. To protect the machine, optional functions such as pressure relief, dry-running protection and water softening can be integrated. For hygienically sensitive areas, the version with a stainless steel housing is recommended, while particularly demanding cleaning tasks are best handled with the hot water version and the option to suck in cleaning agents. The newly developed innovations with the names EASY!Force and EASY!Lock are always included: the EASY!Force high-pressure gun uses the recoil force of the high-pressure jet to reduce the holding force to zero, while the EASY!Lock quick-release couplings enable handling that is five times faster than conventional screw connections without compromising on robustness or service life. Extensive accessories and additional details round off the well-thought-out concept of the HD 9/18-4 ST in a nice way.
