High-pressure washer HDS 6/15-4 C Classic
HDS 6/15-4 C Classic single-phase hot water high-pressure cleaner in the compact class with a durable crankshaft pump, robust tubular steel frame and offering excellent value for money.
Excellent value for money: the single-phase HDS 6/15-4 C Classic compact class hot water high-pressure cleaner with a powerful 4-pole motor. A powerful crankshaft pump builds up the necessary pressure and enables a wide range of cleaning tasks to be carried out efficiently and quickly with the tried-and-tested Classic high-pressure gun. The pressure and water flow can be adjusted depending on the requirements. The integrated water filter keeps dirt particles away from the pump and extends the downtime. The hot water technology even breaks up lubricants effectively and reduces the use of cleaning agents. The highly reliable and maintenance-friendly HDS 6/15-4 C Classic is designed for daily use in hard conditions, whether on construction sites or in the agriculture, automotive or transport industries. A robust tubular steel frame provides protection against impacts, while puncture-proof wheels ensure high manoeuvrability. The machine can also be loaded by crane thanks to an attachment point. The 30-litre fuel tank enables very long operations. There is a practical storage compartment for accessories.
