  • Mobile pressure washing operations
  • Large-scale commercial and industrial cleaning

With 8.5 GPM of water flow and steady pressure, this truck mount pressure washer excels at flushing, rinsing, and cleaning large surface areas where water volume is critical to productivity.

Features

Honda GX690 V-Twin Electric Start Engine

At the core of this truck mount pressure washer is the Honda GX690 688cc V-twin electric start engine, a commercial-grade engine known for power, reliability, and long service life. The GX690 is Honda's heavy-duty V-twin OHV engine, delivering higher torque and power output suited to the high-flow demands of this unit. The electric start system adds convenience and efficiency for truck-mounted applications, especially in high-use professional environments.

Engine features include:

  • Electric start for quick and effortless operation
  • Honda V-twin OHV design for high-torque, high-output performance
  • Strong, consistent power output for high-flow applications
  • Automatic low-oil shutdown to protect the engine
  • 6.7 L / 1.8 GAL fuel tank for extended operation between refueling
  • Engine oil drain hose for easy maintenance

The Honda GX690 engine is covered under Honda's separate engine warranty program.

Industrial-Grade CP CTB2S Belt-Driven Triplex Pump

Paired with the Honda engine is an industrial-grade CP CTB2S P10 class belt-driven triplex pump, engineered for high-flow, continuous-duty pressure washing. The belt drive system reduces pump speed to 1,750 RPM, significantly reducing heat, vibration, and wear during extended operation and extending pump service life beyond direct drive alternatives.

At P10 class, this is the highest pump classification in the BE cold water gas pressure washer range, placing the B4224HETBAS in a category built for sustained high-output industrial and commercial cleaning operations.

Key pump features include:

  • P10 industrial pump class for the most demanding high-flow applications
  • Belt drive system running at 1,750 RPM for reduced wear and extended pump life
  • Smooth, consistent pressure delivery at 4,200 PSI and 8.5 GPM
  • External unloader for adjustable pressure control and dump-to-ground bypass capability
  • Improved cooling for long run times
  • Thermal relief valve to prevent overheating during extended bypass operation

238 Truck Mount Belt Drive Frame with Anti-Vibration Design

The B4224HETBAS is mounted on the 238 Truck Mount Belt Drive Dealer Frame — a powder-coated steel plate purpose-built to bolt through to a truck or trailer frame. Integrated anti-vibration pads reduce movement and stress on components during operation and transport, improving stability and extending equipment life. The mounting system provides confidence for operators who rely on their equipment daily in demanding environments.

Unit Only — Power Unit Configuration

The B4224HETBAS ships as a power unit only. No hose, spray gun, wand, or nozzles are included. This unit is designed to be integrated into a professional truck mount cleaning system with operator-specified hose lengths, fittings, and accessories suited to the specific application. Contact your local BE dealer for guidance on compatible accessories and system configuration.

Warranty and Factory Testing

The B4224HETBAS is backed by a 3-year limited warranty from BE Power Equipment. The Honda GX690 engine is covered separately under Honda's manufacturer warranty program. The pump, mounting frame, and remaining components are covered by BE Power Equipment's warranty.

Each unit is functionally tested at the factory before shipping. Units may contain minimal residual oil or fuel odor, confirming that the machine has passed quality inspections and is ready for installation and use.
