Atlas Copco Oxygen Generator OGP 18

Introduction: The Flow sensor (FI01) is optional and can be ordered in case a measurement of the outlet product flow is required; it measures the flow rate consumption. The flow sensor is to be installed downstream the buffer tank (TK04), behind the pressure regulator (RV04).

Overview of model versus flow sensor: The table below gives an overview of which flow sensor is to be used in combination with which model.

Before carrying out any maintenance or corrective activity read the following recommendations and safety precautions and act accordingly.

• Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar.

The release of nitrogen molecules from the MS is a very slow process. This might cause a pressure build-up in the generator tanks, even after they were depressurized.

Before maintenance, make sure the generator is fully depressurized and purge thoroughly with air to remove all oxygen before service or inspection.

Always vent oxygen to the outside atmosphere.

Due to fire hazard, smoking and the use of open flames are prohibited in the vicinity of the oxygen generator.

Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

• Check for damaged wiring or loose connections, and re-tighten

Safety Precautions: Close the generator's outlet valve and the air inlet valve and wait until machine working pressure is 0 bar. Switch off the generator. Always vent oxygen to the outside atmosphere. Due to fire hazard, smoking and the use of open flames are prohibited in the vicinity of the oxygen generator. Avoid closing valves too fast as gas velocities in the oxygen net might become too high, and create a hazardous situation.

Generator fully depressurized and purged with air to remove all oxygen?

Check for damaged wiring or loose connections, and re-tighten

Replace the in- and outlet filter cartridges

Replace the activated carbon of the filter

Replace the pneumatic valve(s) SV05. Use only oxygen approved grease.

Clean the filter of the electrical cabinet

Replace the pneumatic valves SV01 up to SV04
