Ultra-high-pressure cleaner HD 18/50-4 Cage Classic

HD 18/50-4 Cage Classic: The ultra high-pressure cleaner from the UHP compact class with mobile "cage" design, boasting 30 kW cleaning performance, 500 bar working pressure and a 30 l/min water flow rate.

Suitable for a wide variety of applications, extremely mobile and compact, guarantees optimum cleaning results: The HD 18/50-4 Cage Classic expands our UHP compact class to include cleaning performance of up to 30 kW, making it the most powerful ultra high-pressure cleaner with the mobile "cage" design. A working pressure of 500 bar and water flow rate of 30 l/min guarantee fast results even on the most stubborn dirt, as encountered in the construction trade, industry applications or the transport sector. A rotary switch with intuitive control and the conscious decision to largely eliminate electronic components mean that the device is very easy to use. Ergonomic details, the machine's low weight, its four large wheels and crane hook simplify handling and transporting the unit, even over rough terrain. Where necessary, the HD 18/50-4 Cage Classic can also be transported using aforklift truck, thereby demonstrating maximum flexibility for both transporting and working with the machine.

Features and benefits
Pressure relief valve
  • The pressure relief valve reduces the pressure in the hose, so it remains flexible when the trigger gun is closed.
  • Prevents any sudden recoil for the user, as the pressure is built up slowly when pulling the trigger gun.
  • Significant improvement in handling, for example, makes it easier to switch between working areas.
Outstanding mobility
  • Large wheels, as well as an optimum centre of gravity secure a high degree of mobility for the machine – despite its size.
  • A practical crane hook allows simple transport, also over rough terrain.
