This NorthStar trailer-mounted hot water pressure washer with a self-contained 200-gallon water tank delivers hot water washing anywhere. Perfect for remote job sites with no electricity or running water. The Honda GX630 V-twin engine powers a CAT pump to deliver hot water at 4,000 PSI for effective cleaning.

The horizontal shaft engine is engineered for long life. Cat direct drive pump has brass manifold and ceramic plungers. Coil assembly is fully encased in a custom-molded ceramic fiber refractory combustion chamber with low thermal conductivity and resistance to thermal shock. Parker Hannifin Racor fuel filter and water separator prevent burner ignition problems. Diagnostic lights signal operation of key components. Rear hose-entry spray gun with split lance keeps the hose out of the way for easy handling.
