Guardian G1M Mechanical Washdown System

The Mechanical Washdown System greatly reduces the labor required to wash underneath assets in mining and associated environments. The cannon’s rotation is driven from the pressure of the water and the range of motion is set between 5-360 degrees by 2 mechanical pins.
A clamp style installation system means the cannons are easily installed, adjusted and changed out if required.

Machined one piece nozzle

The nozzle is designed to rotate in its own space. This means that even when the nozzle is surrounded by material it is able to rotate and remove debris from around the cannon, allowing the cannon to be installed in the harshest environments.

Solenoid or manual control

Because the mechanical cannon’s rotation is driven by the pressure of the water, the unit doesn’t require any electrical power to run. This means the units can be turned on and off by a ball valve – though we do recommend the units be controlled by a solenoid valve to ensure accurate washdown timings can be set and controlled remotely, allowing an efficient use of water.


The Mechanical Washdown System’s cannons are housed in a steel guard, protecting users from the rotation of the mechanical impeller that drives the cannons, as well as protecting the cannon from falling product and debris.

Benefits of integrated system

*For example: conveyor must be auto-running, and sump pump must be auto ready for the wash down system to operate.
