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 TSF 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 US-made steel frame with a corrosion-resistant coating 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.
