Design Advantages

Dry Shut system creates back pressure signaling the Nitrogen Regulator to release the right amount of water at the valve
Comes with 4 x ½”NPT (or 9/16MP for 20,000 PSI) ports on the discharge
The standard ¾”NPT connection at the bottom dump port easily routes a hose back to tank or containment area Ideal for contractors required to have a minimal amount of wastewater at the sight of blasting
Nozzles on a multi lancer will maintain pressure until you run out of diesel or until you run out of water
Automated valve control system means less time spent adjusting flow control valves or trying to compensate for nozzle wear
Nitrogen-filled bladder acts as an air shock absorber when the operator engages and disengages the trigger
