Cold-water high-pressure cleaner with robust 4-pole low-speed single-phase motor.

The unit is mounted on rubber feet to prevent vibrations being transmitted to the scaffolding and makes sure the machine does not creep. The motor and electrical equipment are installed in a splash-proof housing. The three-piston axial pump with stainless steel pistons and brass cylinder head guarantees a long service life and exceptional durability. The pressure switch control turns the motor off automatically as soon as water feed is interrupted at the trigger gun. Energy is saved in this way.

Transportation is simple because the unit weighs only 25 kg. It will fit in every station wagon and can also be carried by hand. Finding a suitable power supply is not a problem thanks to the unit's single-phase motor (connected load 3.3 kW). It goes without saying that the HD 600 can also be used for all other cleaning jobs in the workshop or vehicle fleet.
