Arizant Bair Hugger Model 505
Arizant · Model Bair Hugger Model 505
Small size frees up more usable workspace Light weight makes transport and set-up a breeze Freestanding or easily attached to an IV pole, bedrail or optional rolling cart Built-in hour meter makes it easy to monitor usage for preventative maintenance Unique snap-fit hose swivels at three points for easy blanket attachment and positioning.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
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.
Not delivering warm air / temperature fault
HighSymptoms: Air not warm, temperature alarm, over-temp shutdown, blows cold.
Root cause: Heater element, a temperature-sensor / thermal-cutout fault, or a control-board fault.
Low airflow / blower fault
MediumSymptoms: Weak airflow, blanket will not inflate, blower noisy.
Root cause: Worn blower, a blocked intake filter, or a kinked / disconnected hose.
Hose / adapter fault
LowSymptoms: Hose cracked, will not connect to the blanket, air leaks at the coupling.
Root cause: Worn hose or end fitting.
Filter overdue / dirty
LowSymptoms: Reduced airflow, longer warm-up.
Root cause: Clogged intake / HEPA filter.
Over-temperature safety fault
MediumSymptoms: Repeated over-temp alarms even with good airflow.
Root cause: Sensor or thermal-cutout 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.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
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: Fluid / blood / blanket not reaching target temperature
- Confirm the correct programme / set for the fluid type and flow rate.
- Check both heater plates (or the water bath) warm evenly.
- Verify the output temperature against an independent reference at a representative flow.
- Replace the temperature sensor if it disagrees.
- Replace the heater plate / control assembly if output is still low.
Symptom: Over-temperature alarm / shutdown
- Let the unit cool and restart.
- Compare the displayed temperature to an independent reference.
- Check for an extreme flow-rate change during use (fluid warmers).
- Replace the temperature sensor / control board as isolated.
- Confirm stable control across the range before returning to service.
Symptom: Low airflow / blower fault (forced-air) or low water flow (water blanket)
- Replace the intake / HEPA filter (forced-air) or top up and de-air the reservoir (water).
- Check the hose for kinks or splits and confirm the correct blanket type.
- Inspect the blower / circulation pump and impeller.
- Replace the blower / pump if flow is still low.
- Confirm delivered air / water temperature and flow after repair.
