Towable Pressure Washer

The Yanmar diesel engine delivers 8.9 horse power and is designed for optimum performance and longevity. The electric start on this Yanmar engine comes with an ignition warning system to ensure high reliability.

Detergent is fed to the hose via the chemical feed line which filters out unwanted debris. The gear-driven pump is protected by the frame as well as the thermal pump protection and inlet-line strainer.

The BWX pressure washer can achieve a maximum water pressure of 3600 psi, equivalent to 250 bar. 

The 250 gallon (1125 litre) water tank has inbuilt protection from water surges by way of an internal baffle that controls the flow of water whilst the machine is being towed. The tank itself is made of durable HDPE and it has a 550mm lockable cover to keep fluids safely inside.  

The tyres on the bowser trailer are built for industrial conditions and feature moulded mudguards, side reflectors and wheel nut indicators.

Towing is easy thanks to the 40mm towing eye, break-away cable and telescopic jockey wheel/jack. The rear of the trailer has integrated lighting equipment with a 13-pin and 7-pin plug adapter.

On the side of the trailer is a pair of forklift points so that the unit can be safely lifted and transported around site.
