The BE Power Equipment B3213HTBAS Truck Mount Pressure Washer is engineered for professional operators who require a fixed, high-flow cleaning solution mounted directly to a truck or trailer. Delivering 3,200 PSI at 5.5 GPM, this industrial-grade pressure washer provides exceptional water volume and consistent pressure for demanding commercial and industrial cleaning applications where mobility and reliability are critical.
Powered by a proven Honda GX390 389cc recoil start engine and paired with an industrial-grade CP CTB4S P8 belt-driven triplex pump running at 1,450 RPM, the B3213HTBAS is designed for continuous operation in professional environments. Mounted on a powder-coated steel plate with integrated anti-vibration pads, this unit bolts directly to a truck or trailer, creating a stable, secure cleaning platform built for daily use.

Honda GX390 Engine
At the core of this truck mount pressure washer is the Honda GX390 389cc recoil start engine, a commercial-grade overhead valve engine known for durability, reliability, and long service life. Key engine features include:
- Reliable recoil start and smooth operation
- High-torque output suited for belt drive applications
- Automatic low-oil shutdown to protect the engine
- Fuel-efficient OHV design for extended runtime
- 6.1 L / 1.6 GAL fuel tank for extended operation between refueling
The Honda GX390 engine is covered under Honda's separate engine warranty program.
Belt Drive System for Extended Pump Life
The B3213HTBAS uses a gas belt drive system to power the CP triplex pump, running the pump at 1,450 RPM — significantly lower than direct drive configurations. This lower operating speed reduces heat buildup and minimizes pump wear for sustained continuous-duty operation:
- Reduced heat buildup during extended operation
- Lower pump wear for extended service life
- Smoother, more consistent pressure output at high flow rates
- Improved reliability for high-frequency professional use
Industrial-Grade CP CTB4S Triplex Pump with External Unloader
Paired with the Honda engine via the belt drive system is an industrial-grade CP CTB4S P8 class triplex pump with external unloader and adjustable injector. Key pump features include:
- P8 industrial pump class for demanding continuous-duty applications
- Belt drive operation at 1,450 RPM for reduced wear and extended service life
- Thermal relief valve to prevent overheating during extended bypass operation
- Smooth, consistent pressure delivery at 3,200 PSI and 5.5 GPM
External Unloader with Adjustable Injector
The external unloader regulates water flow and pressure when the trigger gun is released. It can be set to dump-to-ground bypass to maximize pump cooling during extended operation — essential for sustained mobile pressure washing use. The adjustable injector allows detergent concentration to be dialled in to match different surfaces and cleaning applications.
238 Truck Mount Belt Drive Frame with Anti-Vibration Design
The B3213HTBAS is mounted on the 238 Truck Mount Belt Drive Dealer Frame — a powder-coated steel plate purpose-built to bolt securely 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 design accommodates the belt drive system while keeping the unit compact at 29" x 20" x 20".
Unit Dimensions - 25" L x 32" W x 27" H
