Overview

This is a contractor-grade cold-water pressure washer Pro-Pack built around a Honda GX390 engine driving an AR Viper heavy-duty belt-drive pump at 4200 PSI and 4 GPM. Belt drive runs the pump slower and cooler than direct drive, so it holds up to long shifts of production cleaning. The package bundles the machine with the tools a working crew needs: a BE 16" flat surface cleaner with a greaseable rotary hub, two 50' commercial-grade non-marking hoses, a 3/8" ball valve for remote shutoff, a detachable chemical injector, and a 5000 PSI gun/wand. It's aimed at pros doing flatwork, fleet, and building washdown who want one ready-to-run kit.

Frequently asked questions

You get the complete kit: the GX390 Honda belt-drive pressure washer, a BE 16" surface cleaner, two 50' high-pressure hoses, a heavy-duty gun/wand assembly, a 3/8" ball valve for remote shutoff, a detachable chemical injector, and 5 spray nozzles (4 stainless QC nozzles plus a brass chemical nozzle).

It's a cold-water pressure washer. The Honda GX390 with the AR Viper belt-drive pump delivers 4200 PSI at 4 GPM using cold water only.

Belt drive turns the pump at a lower RPM than direct drive, which runs it cooler and reduces wear, so the machine is better suited to long, continuous production cleaning.

Yes. The BE 16" surface cleaner is rated to 8 max GPM and 4200 max PSI, so it's matched to this unit's 4 GPM / 4200 PSI output.
