Simpson 3500 PSI 5.5 GPM Gas Powered Hot Water Pressure Washer with 678 CC CRX Engine

The Simpson SB3555131EDC1 is a professional belt-driven hot water pressure washer designed for demanding industrial cleaning applications. It delivers 3,500 PSI at 5.5 GPM, powered by a CRX 680 V-Twin engine with key start ignition and a 7.5-gallon fuel tank, coupled with a Comet RW5535S industrial triplex pump for consistent, high-pressure performance. The 18" horizontal heating coil paired with a 12VDC Wayne diesel burner produces a heat rise of 110–120 degrees fahrenheit, efficiently removing grease, oil, and heavy soils. Built on a large roll-over powder-coated steel frame with 1.5" tubing and equipped with vibration isolators, this unit ensures stability and durability. Professional-grade accessories include a 3/8” x 50’ high-pressure hose, 12 GPM hot water spray gun, 48” insulated lance, six quick-connect nozzles (15 degrees, 25 degrees, 40 degrees, soap), and downstream detergent injection, making it ideal for contractors and industrial cleaning professionals.
