FRU, Vacuum Regulator
ACCUTRON, INC. · Model 26988
A pneumatically-powered device that is a component of an anaesthesia workstation and connects between the expiratory valve or port of a breathing circuit and the extraction system enabling the waste anaesthetic, exhaled, or other trace gasses to be removed under controlled conditions from the work environment and channelled to the outside of the building. Filters or absorbers may be required to clean the removed gasses before discharging to the atmosphere. This device is also known as an anaesthetic gas scavenging system (AGSS).
Key tips
- ·Always leak-test under load - a regulator that reads correctly at rest can still leak and fail in real use.
- ·Canister and tubing changes are an infection-control issue as much as a mechanical one.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Pump / diaphragm wear
MediumSymptoms: Low vacuum, slow recovery.
Root cause: Diaphragm/motor fatigue.
Canister / float valve fault
LowSymptoms: Leak, loss of vacuum.
Root cause: Cracked canister / stuck float.
Filter clog
LowSymptoms: Reduced flow, overheats.
Root cause: Inline filter saturated.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Regulator calibration and leak check
- ·Canister / tubing replacement
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Pump / diaphragm wear
- Confirm the presentation - typically low vacuum, slow recovery - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: diaphragm/motor fatigue.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the diaphragm pump kit per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
