AP175 LN₂ Fogger Guide | Passive dewar-style
The AP175 is a passive dewar-style AP Series liquid-nitrogen fogger. Its published planning profile is ≈ 27–29 m³/min for ≈ 95–110 min, but the exact delivered configuration—not a website summary—must control procurement and protocol use.

Architecture and operating fit
The passive dewar-style family uses dewar boil-off and passive pressure behavior as part of LN₂ delivery. It may appeal to teams that prefer a familiar cryogenic architecture, but readiness, fill state, transfer practice and dewar condition must be controlled.
The published application scope is large environments where a high-output passive dewar architecture is preferred. That is a starting point, not a room-size guarantee. The real decision depends on airflow, room geometry, hose routing, pressure, humidity, visibility and camera requirements.
Specification caution
Ask Applied Physics to identify the current product-sheet revision, electrical service, water volume, LN₂ capacity, output configuration, accessories, warranty, shipping dimensions and factory acceptance evidence in the quote package.
When this model belongs on the shortlist
- Your study scale aligns with: Large environments where a high-output passive dewar architecture is preferred.
- The facility accepts a passive dewar-style operating model.
- The fog-entry method has been demonstrated at the actual pressure boundary.
- The site can support LN₂ receiving, transfer, ventilation and storage.
- Published runtime and output are sufficient with margin—but not grossly oversized.
Protocol integration
Record the equipment ID, configuration, fill state, water type, hose layout, output setting, warm-up/readiness state and any control changes. If the formal study uses a splitter, curtain wand or long hose, qualify that exact arrangement rather than citing the generator’s free-output value.
Build a defensible fogger requirement
Send Applied Physics the room, process, utilities, documentation and safety constraints—not just a model number.
