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.
Low or no smoke capture
HighSymptoms: Smoke lingers in the field, weak suction at the pencil / wand, capture alarm.
Root cause: Saturated ULPA / charcoal filter, a kinked or blocked hose, or a worn blower.
Filter-life indicator / filter fault
MediumSymptoms: Filter-change warning, reduced airflow.
Root cause: Filter at end of life or not fully seated.
Noisy or weak blower
MediumSymptoms: Rising noise, vibration, airflow falling off over time.
Root cause: Worn blower / turbine bearing.
Auto-activation / footswitch fault
LowSymptoms: Evacuator does not start with the ESU or footswitch.
Root cause: Activation sensor or footswitch fault.

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: Weak smoke capture
- Fit a new ULPA / charcoal filter.
- Check the hose and wand for kinks or blockage.
- Confirm the blower reaches full speed.
- Keep the capture inlet within a few cm of the plume.
- Replace the blower if airflow is still low with a new filter and clear hose.
Symptom: Will not auto-start
