Decision framework
Cleanroom Fogger Selection Guide
The best fogger is the smallest system that can deliver interpretable tracer evidence through the real delivery path for the complete study sequence—without exceeding the site’s safety, contamination-control or operational limits.
Use this twelve-field requirement.
- Study purpose and governing protocol or standard.
- Room, enclosure or equipment type and representative operating state.
- Physical dimensions and airflow regime.
- Pressure differential and fog-entry pathway.
- Required visible distance and observation time.
- Number of scenes, interventions and expected repeats.
- Hose length, diameter, bends, splitters, wands and outlet geometry.
- Water quality and process contamination constraints.
- LN₂ availability, staging, transfer and reserve.
- Ventilation, oxygen-monitoring and facility EHS constraints.
- Camera, lighting, background and retained-evidence requirements.
- Schedule, shipping country, training, service and warranty needs.
Technology and architecture gate.
| Question | Yes pathway | No pathway |
|---|---|---|
| Does the evidence require LN₂-class density/throw? | Continue to architecture selection | Evaluate ultrasonic CRF platforms |
| Can the site safely support LN₂? | Continue | Use non-cryogenic method or redesign study |
| Is active self-pressurization preferred? | AP30/AP50/AP100/AP200 family | Evaluate passive AP35/AP95/AP175 |
| Is enclosure pressure significant? | Test delivery pressure/path before sizing | Proceed with normal delivery-loss review |
| Are multiple simultaneous outlets needed? | Evaluate large/multi-output models | Avoid oversizing solely for outlet count |
Use conservative model matching.
The AP Series selector returns a family-level pathway and hard stops. It does not replace a current quotation. Public specifications can conflict, and output at the fogger is not output at the study point.
