Overview
The AR Cordless 4G40 is a battery-powered, cold-water electric pressure washer that delivers 4000 PSI at 4 GPM — the same performance as a 390cc gas engine with none of the fumes, oil changes, fuel storage, or fuel spills. A 52V DC variable-speed motor drives an industrial AR RKV4G40 pump, and a digital control system lets you dial in both PSI and motor RPM so you use only the flow the job needs. The stainless steel frame and cover plate hold up in the field, and because there's no exhaust, it can run indoors. It's built for contractors and operators who want gas-level cleaning power on cordless, emissions-free equipment.
