Allied Healthcare Products Gomco 405
Allied Healthcare Products · Model Gomco 405
Powerful rotary vane pump excels at pharyngeal and nasopharyngeal procedures. Compact the 405 takes up less than one square foot of space. Self-contained unit provides protection against pump and gauge contamination, and allows for easy clean-up. Low maintenance requirements. Durable high-impact plastic case. Disposable hydrophobic bacteria filter eliminates pump flooding and helps prevent fluid and aerosol contamination.
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.
Aspirator will not run
HighSymptoms: Nothing happens on power-up.
Root cause: On/off switch, power cord, or a tripped thermal limit (overheat).
No or weak vacuum
HighSymptoms: Gauge low or zero, poor suction at the catheter.
Root cause: Hydrophobic filter not seated or clogged, canister lid not sealed, a defective canister, or worn rotary-vane pump.
Vacuum at the gauge but not the patient tubing
MediumSymptoms: Gauge builds vacuum, none at the catheter.
Root cause: Clogged hydrophobic bacteria filter or an overfilled canister.
Unable to adjust vacuum
MediumSymptoms: Regulator knob has no effect on the reading.
Root cause: Defective regulator.

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: Will not run
- Push the on/off switch firmly to ON.
- Check the plug at the outlet.
- If it overheated, switch off, wait 15 minutes and clear the vents.
- If still dead, refer for service.
Symptom: No or weak vacuum
- Confirm and tighten the hydrophobic filter and canister lid.
- Replace a clogged filter or a cracked canister.
- With the tubing occluded, check the pump pulls its rated vacuum.
- Rebuild the rotary-vane pump if vacuum is weak with a sealed system.
- Replace the regulator if vacuum cannot be adjusted.
