Our durable hydraulic Hydra-Clean pressure washers are available as cart-mount or wall-mount units and can clean the toughest environements like oil rigs, shipyards, mining, agriculture and construction equipment.

Hydra-Clean pressure washers also carries a safety benefit because there's no risk of sparking, unlike gas or electric pressure washers. The fluid section contains stainless steel wetted parts and can handle the most aggressive cleaning materials up to 200°F (93°C).

  • Hydraulic motor can be powered by existing hydraulic PTO on board equipment
  • Eliminates icing
  • Operates where compressed air sources are not available
  • Designed to use with cold or hot water, detergents or strong chemical solutions up to 200°F (93°C)
  • Supports multiple guns
