Overview

This is a portable, hot water commercial pressure washer rated 3200 PSI at 4 GPM, powered by a 9.8 HP Kohler diesel engine with electric start and a General Pump solid ceramic plunger pump. It runs a 12-volt diesel-fired burner for hot water, so both the engine and the heater burn diesel — no gasoline or external power needed. The self-contained unit rides on a powder-coated steel roll cage frame with 13-inch flat-free tires, a lifting hook, and an 8-gallon poly fuel tank. Built for contractors and industrial crews who need heated water for grease and stuck-on grime and want a single fuel to manage in the field.
