Mojave
AIR TECHNIQUES, INC. · Model H5617
The MOJAVE creates vacuum that will be used in a dental facility. This vacuum system is designed for reliable operation in the modern dental facility. The system uses a 100% oil-less vacuum pump to produce the high-volume air flow required for multiple simultaneous users while the separator tank ensures that no liquids enter the pump. In addition, MOJAVE incorporates an efficient energy management system. This is accomplished by adding a Variable Frequency Drive (VFD) to the Vacuum Pump, which is controlled by a Master Controller. This controller automatically adjusts the frequency of the pu.
Intended use: An assembly of devices designed to aspirate water, blood, saliva, and tooth debris from the oral cavity by means of suction, to maintain a clear operative site during dental surgical, professional hygiene, and orthodontic procedures. It consists of an electrically-powered suction pump with a control knob and patient contact devices (typically suction handpiece/tip); collection containers, spittoon, tubing, and amalgam separator are also often included.
Key tips
- ·Biological-indicator verification applies to dental sterilizers exactly the same as hospital CSSD - no exception for smaller units.
- ·"Sounds different" is often the first real report of handpiece bearing wear, not an outright failure - investigate early rather than waiting.
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.
Output / performance below spec
HighSymptoms: Compressor will not build pressure / cycles constantly; vacuum weak; curing light low irradiance; scanner poor scans.
Root cause: Wear in the core mechanism (compressor head, vacuum pump, LED / lamp, scanner optics) or a control fault.
Water / moisture / drain fault (compressor)
MediumSymptoms: Water in the air lines, drain not working, desiccant exhausted.
Root cause: Auto-drain fault or an exhausted air-dryer / desiccant.
Overheating / thermal cut-out
MediumSymptoms: Unit stops after a period, hot, restarts when cool.
Root cause: Cooling-fan fault, a blocked intake, or a worn motor.
Control / switch / timer fault
MediumSymptoms: Will not start / stop on demand, timer or mode selection unresponsive.
Root cause: Pressure switch, timer, or control board.
Noise / vibration
LowSymptoms: Loud operation, rattling, walking across the floor.
Root cause: Worn mounts, bearings, or loose panels.

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.
- ·Daily handpiece lubrication and autoclave cycle verification
- ·Compressor moisture-trap draining
- ·Annual full PM
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: Output below spec
- Measure the actual output (pressure / vacuum / irradiance) against the spec.
- Inspect the core mechanism for wear.
- Check filters, intakes and drains.
- Rebuild or replace the core mechanism.
- Re-verify output after service.
Symptom: Overheats or will not start on demand
- Confirm airflow and clean the intake / fan.
- Check the pressure switch / timer operates.
- Let it cool and check the thermal cut-out.
- Replace the switch, fan or motor as isolated.
- Confirm normal duty-cycle operation.
