Conmed AER DEFENSE
Conmed · Model AER DEFENSE
Four different modes of operation, making it the most versatile smoke evacuator on the market. 11% (7 dBA) quieter than our previous model. The ULPA-grade filter has 99.9995% efficiency at 0.1 micron particle size. Filter life of up to 35 hours. The AER DEFENSE coupled with the ConMed GoldVac Smoke Evacuation Pencil provides an exceptional combination to protect your staff and patients from the hazards of surgical smoke in the OR.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Cycle fault / abort
HighSymptoms: Cycle stops with a fault code, scope not high-level disinfected, must be re-run.
Root cause: Water fill / drain fault, a leak-test failure, a channel-flow / pressure fault, or a chemistry-delivery fault.
Channel-flow / connector fault
MediumSymptoms: Low-flow or occlusion alarm on a scope channel, incomplete flushing.
Root cause: Wrong or worn hook-up connector, a blocked channel, or a flow-sensor fault.
Leak-test failure
HighSymptoms: The reprocessor's automated leak test fails.
Root cause: A genuine scope leak, or a worn leak-test connector / pump.
Chemistry / disinfectant concentration fault
MediumSymptoms: Low-concentration alarm, MEC test fails, dosing alarm.
Root cause: Empty or expired disinfectant, a dosing-pump fault, or a concentration-monitor fault.
Water-quality / filtration fault
MediumSymptoms: Water-quality alarm, poor rinse, filter-change overdue.
Root cause: Loaded pre-filter / final micron filter, or an RO / water-supply issue.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Cycle fault / abort
- Note the fault code and the phase it aborted in.
- Confirm the correct hook-up connectors for that scope model and that all channels are connected.
- Check the water supply, filters and drain.
- Run the MEC / concentration test.
- Follow the service manual for the specific code.
Symptom: Leak-test failure
- Repeat the manual / bench leak test on the scope to confirm a genuine leak.
- If the scope passes, inspect the reprocessor's leak-test connector and pump.
- Replace the leak-test connector.
- Re-run the automated leak test.
- Quarantine and send the scope for repair if it genuinely leaks.
