AirSep NewLife Intensity
AirSep · Model NewLife Intensity
High Pressure/High Flow Oxygen Concentrator NewLife Intensity combines high pressure with high flow to create the most power-efficient 8 liter per minute (LPM) oxygen concentrator, operating at only 410 watts for reduced power consumption. With an outlet pressure approximately three times higher than most other concentrators, this unit is designed to power respiratory accessories including large volume jet nebulizers, venti-masks, medication nebulizers, and long oxygen tubing runs. The NewLife Intensity 8 LPM oxygen concentrator simplifies a tracheostomy set-up by eliminating the need for a separate external compressor. Administer humidified oxygen to a trach patient by connecting a jet neb bottle directly to Intensity’s O2 outlet. The NewLife Intensity dual flow unit can provide additional power savings by delivering oxygen to two patients simultaneously up to a combined total flow of 8 LPM with one unit.
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
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 O2 concentration alarm
HighSymptoms: Oxygen-concentration alarm, delivered O2 below spec at flow.
Root cause: Aged sieve beds (molecular sieve), a compressor / valve fault, an air leak, or an inlet-filter blockage.
Compressor fault / will not build pressure
MediumSymptoms: Weak or no flow, compressor noisy or hot, thermal cut-out.
Root cause: Worn compressor / valve heads, or a cooling-fan fault.
Flow-control / flowmeter fault
MediumSymptoms: Flow will not adjust or does not match the setting.
Root cause: Worn flow-control valve or flowmeter.
Filter blockage
MediumSymptoms: Reduced performance, compressor working hard.
Root cause: Dirty gross-particle / cabinet / final bacteria filter.
Excessive noise / vibration
LowSymptoms: Loud operation, rattling.
Root cause: Worn compressor mounts or a loose panel.

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: Low O2 concentration alarm
- Verify O2 concentration with a calibrated analyser at the outlet at the rated flow.
- Replace / clean the inlet and cabinet filters.
- Check for air leaks in the pneumatic circuit and at the sieve-bed manifold.
- Replace worn sieve beds.
- Rebuild or replace the compressor / valves if concentration is still low with good sieve beds.
Symptom: Weak or no flow
- Confirm the flow-control valve operates and the flowmeter is not stuck.
- Check the filters.
- Feel whether the compressor builds pressure and is not overheating.
- Rebuild the compressor heads if worn.
- Verify flow and concentration after repair.
