Air Techniques Peri-Pro III
Air Techniques · Model Peri-Pro III
Process all intraoral film sizes 0, 1, 2, 3 and 4 Rollerless transport system Slim space-saving design Easier and faster maintenance, ready to read in only 5 minutes External water drain valve in the base and a refill access door built right into the cover Peri-Pro III has an electronically controlled heating system to maintain an optimum 75° F chemistry temperature Film surfaces are never touched Up to 8 films may be loaded at a time.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
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.
Poor film quality (fog / streaks / light films)
HighSymptoms: Fogged, streaked, mottled or under-developed films; density drift on the sensitometric strip.
Root cause: Exhausted or wrongly mixed chemistry, wrong developer temperature, or dirty / worn rollers.
Film transport jam / mis-feed
MediumSymptoms: Film jams between racks, does not advance, or comes out crumpled.
Root cause: Worn or misaligned transport rollers / racks, worn drive gears, or a crossover-rack fault.
Developer temperature / heater fault
MediumSymptoms: Developer not at set temperature, density varies through the day.
Root cause: Heater, thermostat / sensor, or recirculation-pump fault.
Replenishment pump fault
MediumSymptoms: Chemistry not replenished, developer / fixer levels drift, films degrade over a batch.
Root cause: Worn replenishment-pump tubing or a pump fault.
Dryer fault
LowSymptoms: Films come out damp.
Root cause: Dryer heater or blower fault.

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.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
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: Fogged / streaked / light or mottled films
- Run a sensitometric strip and read Dmin, speed and contrast against the control chart.
- Confirm the developer temperature and that the chemistry is fresh and correctly mixed.
- Clean the transport and crossover rollers and racks.
- Check the replenishment rates and that the replenishment pumps deliver.
- Change the chemistry and re-run the strip.
Symptom: Film jams between racks / does not advance / crumples
- Open the racks and clear the film; note where it hangs up.
- Inspect the rollers, guide shoes and drive gears for wear or misalignment.
- Check each rack is fully seated and aligned.
- Run several test films.
- Replace worn rollers / gears as found.
Symptom: Developer not at temperature / density drifts through the day
- Check the developer heater draws current and the thermostat / sensor reads correctly.
- Confirm the recirculation pump is running.
- Compare the developer temperature to an independent thermometer.
- Replace the heater or thermostat / sensor as isolated.
- Re-run a sensitometric strip.
Symptom: Films come out damp (dryer fault)
- Check the dryer heater and the blower run.
- Confirm the air path and filters are clear.
- Check the dryer temperature setting.
- Replace the dryer heater or blower as isolated.
- Re-run and check for dryness.
