Atlas Copco Oxygen Generator OGP 6

Generator's outlet valve and air inlet valve closed and machine working pressure is 0 bar?

Generator fully depressurized and purged thoroughly with air to remove all oxygen before service or inspection?

Oxygen vented to the outside atmosphere?

No smoking and the use of open flames in the vicinity of the oxygen generator?

Valves closed slowly to avoid high gas velocities in the oxygen net?

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.

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

After maintenance activities, the service counter needs to be reset. Contact your supplier.

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.
