Cleanroom Fogger Comparison
Compare ultrasonic and LN₂ foggers around the actual smoke-study route—not a single output number.
The purchasing problem
Cleanroom fogger comparison tables often mix technologies, operating conditions and model generations while ignoring pressure and hose losses. A defensible comparison starts with the study geometry, permitted working fluid, fogger location, delivery path, visible field, operating sequence and evidence plan.
Decision points that control fit
- Ultrasonic water-based versus LN₂-generated fog
- Compact, medium, high or room-scale output requirement
- Self-pressurized versus dewar-style LN₂ workflow
- Fogger inside the space versus external hose delivery
- Positive, negative or neutral pressure at the outlet
- Single, dual or broader distribution requirement
- Runtime, transport, filling, storage and safety constraints
Selection framework
| CRF2-J | Compact ultrasonic option for localized hoods, cabinets and short routes. |
|---|---|
| CRF3 | Portable mid-scale ultrasonic option for localized to moderate studies. |
| CRF6 | Higher-output ultrasonic platform with dual 80 mm outlets. |
| AP30 | Self-pressurized LN₂ option for medium-output ultrapure fog applications. |
| AP35 | Dewar-style LN₂ platform for higher-purity, longer-distance studies. |
| AP50 | Higher-output self-pressurized LN₂ platform. |
| AP95 | High-volume dewar-style LN₂ system for larger and longer studies. |
The framework narrows the technical path. Current manufacturer configuration, price, lead time, availability and included documentation are quotation-stage facts.
Compare the evidence before selecting the model
Quote the complete working package
Accessories, hose assemblies, standards, certificates, transport, installation, training and validation documents can determine whether the system is usable. A low base-unit quote with missing scope is not a lower-cost solution.
Commercial and specification questions
The selector and page content narrow the requirement. The formal quotation confirms the current configuration, commercial terms and included documentation.
Which cleanroom fogger is best?
There is no universal best model. The right starting point depends on technology constraints, geometry, pressure, placement, output, runtime and procedure.
Are AP30 and AP35 the same type of LN₂ fogger?
No. GSE treats AP30 as self-pressurized and AP35 as dewar-style.
Is CRF6 always better than CRF3?
No. CRF6 adds output and dual outlets; CRF3 may be easier to control and transport for localized studies.
Should the highest-output fogger be selected for safety?
Not automatically. Oversizing can complicate handling and can disturb or obscure the airflow being observed.

Fogger choice depends on the enclosure, visibility, duration, residue policy and delivery path
Use the page to build requirements, then confirm the actual model and accessories in writing.
Turn this research into a controlled technical request.
Send the application, model, specification or drawing. GSE will preserve the technical lane, identify missing scope and verify current commercial details without treating website copy as an offer.
