Stealth 8 GPM 4000 PSI Belt Drive Pressure Washer (Gas - Cold Water) w/ CRX Engine and General Pump

Stealth Operator Series 8 GPM 4000 PSI Belt-Driven Commercial Pressure Washer Skid – CRX 680 & General Pump TSF2021

The Stealth Operator Series 8 GPM 4000 PSI Pressure Washer Skid delivers the same industry-proven cleaning performance contractors expect from the Operator Series platform while providing a more budget-conscious alternative to Honda-powered configurations. Combining high water volume with commercial-grade pressure, this machine is built to tackle residential concrete cleaning, commercial property maintenance, fleet washing, heavy equipment cleaning, agricultural cleaning, and large-scale flatwork production.

Powered by the CRX 680 V-Twin Electric Start Engine and paired with the legendary General Pump TSF2021 belt-driven triplex plunger pump, this system delivers the flow, pressure, and reliability professional contractors need for daily production work. The belt-drive design reduces pump RPM, heat, and vibration while improving water-drawing capability from buffer tanks, making it a preferred configuration for trailer-mounted and skid-mounted pressure washing systems.

Every Stealth Sprayers machine is built on a premium 6061-T6 structural aluminum skid platform. Constructed from precision-cut aluminum, the skid provides exceptional strength while remaining lightweight and corrosion resistant. Integrated anti-vibration mounting feet help isolate engine and pump vibration, contributing to quieter operation, reduced component fatigue, and a more refined operating experience. The skid also features improved service access, maintenance-friendly layouts, and laser-cut STEALTH branding that gives the system a professional appearance on trailers, truck beds, and mobile wash rigs.

Every Stealth pressure washer arrives prefilled with oil and includes both engine and pump oil drain hoses for simplified maintenance right out of the box.

Whether you're launching a pressure washing business, upgrading from a smaller machine, or expanding an established fleet, the Stealth Operator Series 8 GPM 4000 PSI skid provides professional-grade cleaning performance at an exceptional value.

Frequently Asked Questions

What can an 8 GPM 4000 PSI pressure washer clean?

An 8 GPM 4000 PSI pressure washer is commonly used for concrete cleaning, commercial property maintenance, fleet washing, agricultural cleaning, heavy equipment cleaning, parking garages, drive-thrus, industrial facilities, and large-scale flatwork applications.

What size surface cleaner can an 8 GPM 4000 PSI pressure washer run?

Most contractors run a 28" to 36" surface cleaner with an 8 GPM machine. A 32" surface cleaner is often considered the ideal balance between productivity and cleaning performance.

Why is 8 GPM considered the industry workhorse?
