Operational Benefits:

• Quick and Simple Installation – No need for tank modifications, enabling seamless retrofitting.

• Vacuum Shut-Off Mechanism – Shields plastic tanks from positive pressure buildup.

• Dry-Break Technology – Minimizes spills, ensuring a cleaner, safer workspace.

• High Flow Capacity – Handles flow rates up to 10 GPM (38 L/min).

• ISO 22241 Compliance – Materials meet stringent ISO standards for DEF handling.

Cost-Efficiency Highlights:

• Automatic Shut-Off – Prevents overfilling, reducing waste and cleanup expenses.

• Pre-Set Fill Levels – Ensures accurate and consistent refueling every time.

• User-Friendly Operation – Functions similarly to the Posilock 105 Diesel Refueling System, eliminating the need for additional training.

• Exclusive System Interface – Prevents compatibility with other systems, eliminating the risk of cross-contamination.

1. Attach the Nozzle: Secure the nozzle to the adapter and activate the lever.

2. Pressure Generation: Fluid movement creates low pressure in the trip rod assembly.

3. Airflow Control: Air from the tank flows upward through the sensing tube into the trip rod assembly.

4. Vacuum Formation: When fluid reaches the sensing tube outlet, airflow stops, creating a vacuum.

5. Shut-Off Activation: The vacuum triggers a diaphragm, automatically halting the fueling process.
