The Kärcher HD 6/15-4 M ST Classic is a durable and powerful stationary high-pressure washer designed for intensive use in industry, agriculture, and the municipal sector.
The core of the unit is a robust crankshaft pump with a brass cylinder head, ensuring long-term reliability and allowing for adjustment of both water flow and working pressure according to the surface being cleaned.
Thanks to the 4-pole low-speed motor, the washer operates very quietly and vibration-free, while simultaneously reducing wear on the pump and maintenance needs.
The modular design and EASY!Lock quick-connect couplings make using the unit and changing accessories extremely convenient and fast, while ensuring easy access to all important components.
