Shark-Karcher Pressure Washers has introduced for the rental industry a new line of compact, gasoline-powered cold-water pressure washers ideal for high-pressure cleaning around the home or in occasional-use applications. The three models of the RG series are powered by Honda engines (5.5, 6 and 13 HP) with cleaning power of up to 3.6 gallons per minute (GPM) and 4000 pounds per square inch (PSI). Two of the units weigh less than 100 lbs. The RG series features a Shark-Karcher high-pressure axial pump with stainless steel pistons and forged brass manifold backed by a limited one-year warranty. All three models feature precision-welded chassis, protected by an epoxy, powder-coat wrinkle paint, and come with pneumatic tires for easy maneuvering in all terrain. Other features include a heavy-duty, insulated trigger gun, chrome-plated wand, a selection of color-coded stainless steel nozzles, detergent injection and 25 or 50 feet of high-pressure hose.
