Superior Systems for Underwater Cleaning… The system is based on the principles of cavitation, when collapsing bubbles generated by a proprietary system create a vacuum that quickly and safely removes fouling materials. The advantages of this system over conventional high pressure blasting, grit blasters, barnacle blasters or brush cleaning are many: The systems are safe to use. The water stream will not inflict damage to a diver who may come in contact accidentally. The lance grip nozzle system is compact, enabling cleaning of geometrically complex surfaces. All types of marine growth, from seaweed to hard well-attached barnacles, are easily removed, with only one pass, saving operators time and money. Surfaces with paint, varnish or anti-fouling coatings are not disturbed when cleaned, and heavy metals or other contaminants are not released into the water. The systems use either fresh water or seawater. The cavitation system leaves a smooth surface that retards biological growth and decreases cleaning frequency. Can be used on materials such as painted metal, unpainted metal, concrete, plastic, wood, rubber, glass, fiber and fiberglass. Typically used on boat hulls, offshore platforms, pilings and piers, pipelines, intake grates, ship propellers, tanks, fishing nets and buoys. The 1222 comes with two guns, one for use below the surface and one for use above the surface. The 1222 is available either with either gas or electric power.
