Water blasters HD 8/18-4 M Plus

Compact, mobile, unheated high-pressure cleaner HD 8/18-4 M with 4-pole, slow-running three-phase motor and automatic pressure relief. High cleaning performance and energy-efficient.

Designed for upright and horizontal operation, our compact, mobile and powerful high-pressure cleaner HD 8/18-4 M ensures maximum flexibility in use. Practical details such as servo control, our system for controlling the water volume and working pressure directly at the trigger gun, or also the simple manoeuvrability and the low spatial requirement of the reliable device, guarantee maximum comfort. Powered by a 4-pole, slow-running three-phase motor with pressure switch control, the new pump engineering ensures 20 percent higher cleaning performance and energy efficiency. The automatic pressure relief protects the high-pressure components against damage in stand-by mode. Effortless work and time-saving set-up and dismantling are guaranteed with the EASY!Force high-pressure gun, which makes use of the recoil force of the high-pressure jet in order to reduce the holding force to zero, andthe EASY!Lock quick-release fasteners for 5-times faster handling compared to traditional connections without having a negative impact on robustness and durability. Several options are available for the safe storage of accessories directly at the device during transportation.
