Overview

This is a skid-mounted commercial cold water pressure washer delivering 8.0 GPM at 3500 PSI, powered by an electric-start Honda GX690 engine driving a General low-RPM pump through a 3V X cog belt system. The belt drive keeps pump speed down for long service life, and the block-mounted, flow-activated K7 unloader with bypass return-to-tank and a thermo-sensor protect the pump in bypass. It's built on a heavy-duty stainless steel skid and is set up for tank feed through a 1" brass barbed inlet — mount it on a trailer, deck, or truck bed. Every unit ships factory assembled and tested in the USA. Standard configuration is not for sale in California; a CARB-compliant upgrade is available. Battery not included.

Frequently asked questions

This 8 GPM unit is set up for tank feed — plan on supplying it from a water tank through its 1" brass barbed inlet rather than a garden hose. The skid frame is designed to mount alongside a tank on a trailer, deck, or truck bed, and the bypass hose returns water to the tank.

It ships with a heavy-duty 5000 PSI gun/wand assembly, 50' of 4200 PSI hose with QC couplers, a 20% detachable downstream chemical injector, 4 color-coded stainless QC spray nozzles, a brass QC chemical nozzle, a remote 6-gallon poly fuel tank, and a marine-grade battery box. Units arrive factory assembled and tested.

No — the standard unit is not for sale in California because its remote poly fuel tank is not CARB evaporative compliant. A California-compliant upgrade is available as an option; contact us if you need the CARB version.

Belt drive lets the General pump run at low RPM, which reduces wear and extends service life. The 3V X cog belt system provides balanced power transfer, and a single-bolt engine adjustment with an interlocking belt cover makes tensioning and service straightforward.
