Overview

This is a portable commercial hot water pressure washer delivering 4200 PSI at 4 GPM, powered by a 14 HP Kohler Command Pro 440cc engine with electric and manual start. The engine runs an AR Viper industrial direct-drive pump (VV4G42G), and a Beckett diesel burner with adjustable thermostat control heats the water through a schedule 80 coil with stainless steel wrap, fed by an 8-gallon onboard burner fuel tank. It's built on an HD US steel roll-cage frame with a lifting hook, 13-inch flat-free tires, and a compact 39" L x 31" W x 49" H footprint, so one operator can move it around a job site. Every unit ships factory assembled and tested in the USA, ready to run. Not for sale in California (a CARB-compliant upgrade is available).
