Hisaki Japan Electric Pressure Washer 5hp Motor SINGLE PHASE 3450PSI

The Hisaki Japan 15M26 Electric Pressure Washer with a 5 HP motor is a heavy-duty, commercial-grade cleaning system. Stepping up from the 3 HP (14M20) model, the 15M26 delivers a powerful 3,450 PSI while operating on a standard single-phase power supply, making it one of the most powerful single-phase electric pressure washers available for commercial car wash bays, transport fleets, and industrial maintenance.
