Kärcher’s HDS middle class hot water pressure washers reach very high levels of performance, reliability and economy. With innovative features such as the eco!efficiency mode, offering fuel savings of up to 20% without compromising cleaning performance, 4-pole motors for high performance and long life, on-board diagnostics, and 3-year burner coil warranty, the HDS middle class range provides our customers with the toughness, cleaning power, and low running costs they demand. The HDS 7/9-4 M features a 4-pole, air-cooled 110V electric motor with long-life bearings and a 3-piston axial pump with ceramic pistons. With water flow of up to 700 litres per hour, and up to 90 bar pressure, the 7/9 is a great all-round machine with superb performance for daily and deep cleaning jobs where 110V power supply is required.
FEATURES AND BENEFITS
Efficiency
In the Eco setting the unit operates in the most economical temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation.
Maximum efficiency
Highly efficient burner technology. 4-pole, slow-running electric motor guarantees a long working time.
Operational reliability
The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.
