DYNAJET
Spray lance SL2800 R72
This spray lance is designed for professional high-pressure cleaning units with a matching electrical control system. It combines manual spraying with remote switching at the handle for controlled pressure delivery and safer operation.
Working pressure should match the task. Surface preparation and general maintenance typically use 150 to 500 bar, while industrial coating removal and concrete work require higher pressure. Contact your nearest distribution partner for guidance on the right pressure and flow rate for your specific job.

Remote-controlled spraying for precise operation
The Lance SL 2800 R72 is a professional spray lance for use with DYNAJET high-pressure cleaning systems that are equipped for electrical control. It is intended for applications where the operator needs direct control of the spray process from the working position, while maintaining a practical and safe handling concept.
The integrated remote switch in the handle allows the pump to be changed between pressure and pressureless delivery without leaving the spraying location. This supports efficient work sequences and makes the lance well suited to demanding cleaning tasks where frequent start-stop operation is required.
An automatic trigger lock adds a further level of operational security and helps prevent unintended activation. The lance can also be used in a mechanical holding device, making it a flexible solution for professional setups where stable guidance and reliable control are important.
It is supplied as the lance assembly without thrust rings and thrust bolt, allowing it to be combined with the matching lance tubes and accessories for the intended application.
Description
The spray lance can only be used in combination with a high-pressure cleaning unit whose electrical control system is specially equipped for this purpose.
The trigger lever locks automatically so that unintentional operation is not possible. The spray lance can be used for manual spraying or it can be clamped in a mechanical holding device. mechanical holding device.
The spray lance is equipped with an electric remote switch located in the handle. With the operator/user can switch the pump to pressure or pressureless delivery from the spraying location. delivery. The remote switch is connected to a solenoid valve via the electrical control of the pump unit. solenoid valve, which e.g. controls the compressed air supply to the air-actuated pump-changeover valve.
When the trigger is actuated, the remote switch reacts and switches the pump over via the changeover valve so that it delivers into the spray lance and builds up pressure. The spraying process begins.
When the trigger is released again, the pump is switched off to pressureless delivery. The spraying process is interrupted.
If the recoil force exceeds 150 N, the spray lance must be equipped with a shoulder support, which we supply on special order.
