Direct answer: choose between AP30 and a CRF ultrasonic fogger based first on the facility’s working-fluid procedure and operating constraints. AP30 is a self-pressurized liquid-nitrogen platform; CRF3 and CRF6 are ultrasonic water-based systems.
Why the technologies should not be treated as interchangeable
Both produce visible fog, but the inputs, operating controls and delivery behavior differ. A facility with an established LN₂ method may prefer the AP platform. Another may require DI, sterile water or WFI operation and therefore use a CRF system.
AP30 decision factors
- LN₂ supply and handling capability
- Facility EHS and operator procedures
- Self-pressurized delivery requirement
- Test geometry and hose path
- Training, accessories and document needs
CRF decision factors
- Approved water input
- Required ultrasonic output
- CRF3 versus CRF6 scale and outlet routing
- Pressure relationship and hose restrictions
- Cleaning and controlled-environment procedure
Compare the complete operating package
Do not compare only the base units. Include working fluid, accessories, hose assemblies, controls, operator steps, facility review and the procedure used to record the study.
Common mistake: choosing by fog appearance alone
Dense fog in a demonstration video does not prove performance in a positive-pressure isolator or through a long restrictive hose. Provide the actual geometry and delivery path.
RFQ package
Send the test-space dimensions, pressure relationship, fogger location, hose route, desired visual distance, working-fluid requirement and operating constraints. GSE can then route the request to the appropriate airflow visualization platform.
