Air-Operated Pressure Washing for Hazardous & Wet Areas
The Graco Hydra-Clean is an air-driven (pneumatic) pressure washer package engineered for plants, workshops and sites where electric or petrol-powered units aren't an option. With no electric motor and an ATEX-rated NXT air motor, it is ideally suited to wet washdown and hazardous-classified areas, sanitising, and heavy industrial cleaning with cold or hot water.

Every package includes:
