Overview
This is a skid-mount cold-water pressure washer built on a Honda GX390 engine and a General Pump industrial pump, rated at 4000 PSI and 4.0 GPM. The belt-drive layout runs the pump at low RPM off the engine through a 3-V cog belt, which cuts heat and wear so both the engine and pump last longer under daily use. The heavy-duty domestic steel frame carries a corrosion-resistant coating and sits on four solid-rubber iso-pads to tame vibration. Low-oil shutdown protects the engine and a pump thermal valve guards against overheating. It's made and assembled in the USA and built for contractors running tough cleaning jobs day in and day out.
