Karcher HD 9/100-4 - High Pressure Cold Water Pressure Washer
Karcher HD 9/100-4 , a trolley-mounted high-pressure washer ideal for continuous use in the construction sector and in industrial applications where great power is required to remove stubborn dirt and encrustations . High performance is guaranteed by a WOMA industrial pump with high volumetric efficiency, capable of developing a pressure of 1000 bar and a flow rate of 980 L/h ; the pump features a carbide piston that guarantees long life and has been developed with a design that allows for easy replacement of parts subject to wear such as valves, gaskets and pistons.


The pressure washer is part of Karcher's UHP class and therefore has a compact and very robust structure , making it ideal for use in difficult conditions and on construction sites; the large wheels allow for easy movement even on uneven terrain and the upper hook facilitates movement using cranes or forklifts.

The Karcher HD 9/100-4 features a convenient and intuitive central selector , hour meter, and pressure gauge; it comes with a special gun with an ergonomic grip that requires less trigger force to make the operator's job easier. The machine is also equipped with a pressure relief valve that reduces pressure in the hose and ensures it remains flexible when the gun is closed; the valve also prevents kickback when pressure increases with the gun open.
