Karcher HD 6/11-4M St Cold Water Pressure Washer 1.524-939.0

The Kärcher HD 6/11-4M ST is a compact, stationary cold water pressure washer designed for professional and industrial use where space-saving installation is essential. Unlike mobile units, this model is built as a stand-alone pump unit, making it ideal for fixed installations such as production lines, wash bays, and workshop setups.

Designed for flexibility, the unit can be mounted both vertically and horizontally, with a robust 3-point mounting system allowing secure wall installation. Its compact footprint makes it perfect for environments where floor space is limited while still delivering strong cleaning performance.

At its core is a durable high-pressure pump with a brass cylinder head and a powerful electric motor, ensuring reliable operation and long service life. The machine also features automatic pressure relief, protecting internal components and extending lifespan.

Serviceability is a key advantage, with easy access to the pump and electrical components for quick maintenance. A large, easily accessible water fine filter protects the pump from dirt particles, making it suitable for demanding environments and reclaim water systems.

With a flow rate of 600 l/h, operating pressure of 110 bar, and maximum pressure of 165 bar, the HD 6/11-4M ST delivers consistent, efficient cleaning performance for professional applications.
