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.
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.
