Product Summary

The NorthStar Gas Cold Water Pressure Washer is engineered for professionals who demand premium components and long-lasting performance. Producing 4,000 PSI and 3.5 GPM, it provides the cleaning power needed to tackle heavy equipment, agricultural machinery, buildings, concrete, trailers and commercial vehicles with ease. Powered by a Honda GX390 commercial engine, this pressure washer delivers dependable starting and proven reliability for demanding daily use. The belt drive system allows the Cat triplex plunger pump to operate at lower RPMs than direct drive systems, reducing heat buildup, vibration and component wear to help maximize pump life. A downstream detergent injection system improves cleaning performance while protecting the pump from harsh chemicals, and the included 50ft. high-pressure hose provides extended reach for greater productivity on large jobs. Built with professional-grade components throughout, the NorthStar Gas Cold Water Pressure Washer is designed to deliver reliable cleaning performance season after season.
