Overview
The DWM4020G is a wall-mount cold water electric pressure washer rated 2000 PSI at 4.0 GPM, driven by a Marathon Electric 6.0 HP motor on 230V single-phase power. A heavy-duty GP General Pump industrial pump runs direct-drive, and the whole unit hangs on a corrosion-resistant aircraft-grade aluminum frame — off the floor, out of the work area, and always plumbed and ready. It ships with a gun-wand assembly, 50-foot high-pressure hose with quick connects, 10% chemical injector, and five color-coded QC nozzles, with a 12-foot power cord ready to hardwire. Built for everyday use in wash bays, shops, and equipment yards; assembled in the USA. An Auto-Start/Stop version (DWM4020G/AUTO) is available.
