Overview

This is a commercial cold-water pressure washer that puts out 4000 PSI at 4 GPM, driven by a Honda GX390 gasoline engine paired with a General Pump. Power transfers through a heavy-duty direct-drive setup, and the whole unit rides on an aircraft-grade aluminum frame with dual handles and no welds to fail, so it stays light and corrosion-resistant in the field. Built for all-purpose commercial cleaning where you need real pressure and volume day in and day out. Low-oil shutdown protects the engine, and a thermo-sensor guards the pump against overheating in bypass mode. Note: not for sale in California.
