DynaRest Airfloat 300 Air Mattress with Pump
DynaRest Airfloat 300 Air Mattress with Pump.
Intended use: A mattress-like device consisting of an arrangement of alternating-pressure air cells designed to be placed on a bed mattress support platform to provide a comfortable surface on which an occupant can lie, rest, and sleep, and intended to distribute body weight over a large surface area typically to help relieve pressure points for comfort and improve blood circulation to prevent pressure sores. It is connected to an alternating-pressure pump (not included) which provides the inflation/deflation control. It is commonly used for elderly immobilized (especially in cases of decubitus ulcers) patients, patients with disabilities, or patients with low body fat.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Surface will not inflate / not firm enough
HighSymptoms: Patient bottoms out, low-pressure alarm, surface stays soft.
Root cause: Pump fault, a hose disconnect or kink, or an air-cell / bladder leak.
One cell / zone stays flat
MediumSymptoms: Localised loss of support.
Root cause: Perforated air cell or a failed cell connector.
Alternating cycle not working
MediumSymptoms: Cells do not alternate.
Root cause: Rotary valve / distribution manifold fault in the pump.
Cover damage
LowSymptoms: Tears or cracking, fluid ingress.
Root cause: Wear or sharp objects.

- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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: Surface will not firm up
- Confirm the pump runs and power is on.
- Check the supply hose connections and inspect for kinks.
- Listen / feel for pump output.
- Replace the pump if it runs without output.
- Verify the surface holds pressure under a representative load.
Symptom: Cells not alternating
- Confirm alternating mode is selected.
- Listen for the rotary valve cycling in the pump.
- Check the manifold and hoses.
- Replace the rotary valve / manifold if it will not cycle.
- Confirm a full cycle.
