Top Dent S-Vac Vent
J.H. Orsing AB · Model Scantube
A semi-rigid or rigid hollow tubular component of a dental suction system designed to be inserted into the oral cavity for the aspiration and removal of blood, pus, saliva, debris, and water during a dental procedure. It is typically made of disposable plastic materials. This is a single-use device.
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
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.
Will not reach or hold set negative pressure
HighSymptoms: Low-pressure / leak alarm, therapy pauses, dressing not collapsing.
Root cause: Dressing / canister leak, worn tubing / connectors, a worn pump, or a pressure-sensor fault.
Canister / blockage alarm
MediumSymptoms: "Canister full" or "blockage" alarm, therapy stops.
Root cause: Full or mis-seated canister, a clot / gel in the tubing, or a canister-sensor fault.
Battery will not hold charge
MediumSymptoms: Short run time, will not reach full charge.
Root cause: Aged battery pack.
Pump / vacuum-source fault
MediumSymptoms: Cannot build pressure with a sealed test, pump noisy or dead.
Root cause: Worn pump / diaphragm or motor.
Display / control / alarm fault
LowSymptoms: Unresponsive keys, blank display, no audible alarm.
Root cause: Display / keypad, or the alarm / control board.

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 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: Will not hold set pressure
- Cap the tubing at the pump and confirm it can build and hold the set pressure.
- Fit a fresh canister and tubing set.
- Check the dressing seal on the patient (a leak is the most common cause).
- Verify pressure against a gauge if the device allows.
- Replace the pump or pressure sensor as isolated.
Symptom: Canister or blockage alarm
- Reseat or replace the canister and confirm it clicks home.
- Inspect the tubing for a clot / gel and clear or replace it.
- Check the canister sensor / float.
- Restart therapy.
- Replace the canister sensor if it alarms with a good canister.
