The HD 10/21-4 S cold water washer in upright design impresses with EASY!Force spray handle, pressure control and a rotatable stainless steel spray pipe lance.
The HD 10/21-4 S cold water cleaner with three-phase operation combines high user-friendliness with an impressive power of 210 bar and a maximum water flow of 1,000 l/h. Thanks to its upright design, the machine requires less space than conventional models and is easier to maneuver, especially around obstacles. The large, rubber-coated wheels also make transport easy, even on uneven surfaces. Storage solutions are included to keep accessories organized – for example, a separate nozzle compartment for safe storage of unused nozzles. Innovative functions simplify handling and save time during both setup and disassembly. EASY!Force The spray gun uses the recoil force of the high-pressure jet to eliminate the need to hold the trigger, while EASY!Lock Quick-release couplings make assembly five times faster than traditional screw couplings, without compromising durability or service life. The HD 10/21-4 S is designed for daily use in harsh environments. A detergent-resistant brass cylinder head and stainless steel pistons with ceramic coating ensure a long service life.
