Product information and benefits

While many equipment features of our HD 9/18-4 ST cold water high-pressure cleaner are freely configurable, a working pressure of 180 bar and a flow rate of at least 900 l/h also mean that it earns the title "all-rounder" for a variety of fields of application from industry to agriculture. Optional functions such as pressure relief, dry-running protection and water softening can also be integrated to protect the machine. For hygiene-sensitive areas, there is a variant with stainless steel casing, while very demanding cleaning tasks are best tackled with the hot water version and the option to suction cleaning agents. The recently developed innovations EASY!Force and EASY!Lock are always on board: While the EASY!Force high-pressure gun makes use of the recoil force of the high-pressure jet to reduce the holding force to zero, the EASY!Lock quick-release fasteners enable handlingthat is five times faster than with conventional screw connections, without losing any robustness or longevity. An extensive range of accessories and added details complete the sophisticated concept of the HD 9/18-4 ST.
