Short answer: select airflow visualization equipment from the test geometry backward. Define the space, pressure relationship, required fog travel, working-fluid restrictions and placement of the fogger before choosing a model.
1. Define the test space
A biosafety cabinet, barrier isolator, pass-through and room are not interchangeable applications. Record the internal dimensions and where fog must enter the space. For enclosed equipment, note glove ports, doors, return paths and other features that shape airflow.
2. Identify pressure relationships
Positive pressure can resist fog introduced from outside the enclosure. Negative pressure can pull fog in rapidly. If the fogger must remain outside the test space, the system has to overcome the combined effect of pressure, hose length and restrictions.
3. Set the required visual distance
Do you need to see airflow a few feet from the outlet, across an isolator, or through a much larger room? This helps determine whether a portable ultrasonic system or an LN₂ system is more appropriate.
4. Confirm working-fluid constraints
Some facilities prefer DI, sterile or WFI water-based ultrasonic fogging. Other studies are designed around liquid-nitrogen fog. The facility’s procedure and contamination-control requirements should be resolved before equipment selection.
5. Plan hose and outlet routing
Every hose, reducer and bend adds restriction. Long or undersized hose can materially change delivered fog. Send the planned routing with the RFQ instead of assuming the standard outlet configuration will behave the same after several meters of hose.
6. Match the model
GSE’s featured range includes the CRF3 for portable/mid-scale ultrasonic work, the CRF6 for higher ultrasonic output, and the AP30 for self-pressurized LN₂ fogging.
Best RFQ package: drawing or dimensions + pressure relationship + fogger location + hose route + desired visual distance + working-fluid preference.
Use the GSE quote form to send those details before the model is locked into a procurement request.
7. Define the recording and acceptance plan
Fog density is not the only issue. The study needs a camera position, lighting approach, duration and acceptance method. Equipment and accessories should support the way the airflow will actually be observed and documented.
8. Confirm facility controls
Review power, working-fluid, ventilation, operator access, cleaning and EHS requirements. The quote should include the operating configuration the facility can support, not merely the base fogger.
