The compact, lightweight, and versatile cold water high-pressure cleaner HD 5/12 C impresses with excellent mobility and is suitable for both vertical and horizontal operation. The device features a sophisticated accessory storage system and promises a long service life thanks to its brass cylinder head and automatic pressure relief. Also included in the equipment package are the newly developed EASY!Force high-pressure gun and the EASY!Lock quick couplings. While the EASY!Force high-pressure gun utilizes the recoil force of the high-pressure jet to reduce the holding force to zero, the EASY!Lock quick couplings allow for handling that is five times faster compared to conventional screw connections, without compromising on robustness and durability. Fatigue-free working and time-saving setup and dismantling are thus standard features, representing the successful overall concept of the device.
