SeQual Integra
SeQual · Model Integra
• Easy-to-read LCD flow indicator. • The new flat panel cleans with a quick wipe. • Alerts you if the O2 hose becomes restricted. • Delivers up to 10 LPM of continuous O2 with the security and convenience only a concentrator can provide. • Single, easy-to-clean cabinet intake filter is highly visible and easy to reach and remove for periodic cleaning. • Compact cabinet with integrated handle and four swivel casters make movement easy. • Hour meter can be easily accessed and viewed by service technician. • Essentially the same size, weight, and power consumption as a 5 LPM machine. • Internal 9 volt battery, with provider accessible reserve gauge, powers alarm if electric service is interrupted.
Key tips
- ·Don't extend filter/tubing replacement intervals to save cost - this is an infection-control issue, not just a performance one.
- ·Flow accuracy drift is often the earliest sign of a failing sensor, well before an outright alarm.
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.
Oxygen concentrator sieve bed wear
HighSymptoms: Low O2 purity, alarm.
Root cause: Zeolite sieve exhaustion.
Compressor fault
HighSymptoms: Low flow, overheat.
Root cause: Worn compressor.
Suction pump failure
MediumSymptoms: Low vacuum, no suction.
Root cause: Diaphragm/motor wear.
Humidifier element fault
LowSymptoms: No humidity, overheat.
Root cause: Heater plate failure.

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.
- ·Filter and tubing replacement
- ·Flow accuracy check
- ·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: Oxygen concentrator sieve bed wear
- Confirm the presentation - typically low O2 purity, alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: zeolite sieve exhaustion.
- 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 sieve bed (zeolite) 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.
Symptom: Compressor fault
- Confirm the presentation - typically low flow, overheat - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn compressor.
- 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 compressor 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.
