Karcher - HD 7/18-4 M 3 Phase Cold Water Pressure Washer

Karcher HD 7/18-4 M Three Phase Pressure Washer, Cold Water - 400V, 180 bar

The Karcher HD 7/18-4 M is a 400V three-phase pressure washer for cold water cleaning in commercial and industrial settings, built around a low-speed four-pole motor for intensive use. Pressure can be set anywhere from 30 to 180 bar, with a 215 bar maximum, and water flow from 240 to 700 L/h. Both are adjusted from the trigger gun through Servo Control. The Easy Press gun has a soft grip and needs less force to hold the trigger open. Detergent is added through SwitchChem, an infinitely variable dosing system with a two-way valve, so two different cleaning agents can be connected and selected as needed. The motor is air and water cooled, the connection load is 5kW, and the machine can be fed with water up to 60°C. For moving between jobs, it stands upright on large wheels that handle uneven ground, with storage for the power cord at the back and a holder for the lance. Each machine comes with a 10m high-pressure hose, a 1050mm stainless steel lance that rotates under pressure, and a triple nozzle with 0°, 25° and 40° settings.

Key Features & Benefits
