Ultrapure Fogger, LN2 Fog Generator

The AP32 ultrapure Nitrogen fogger has been superseded by the AP35 Ultrapure Fogger with more fog volume and fog density. AP32 uses liquid nitrogen and DI water or water for injection to produce a dense, ultrapure fog at 493 ml per minute, to provide superb visualization of airflow, patterns, direction, turbulence, dead zones and velocity for up to 70 minutes in clean rooms, ISO suites, sterile rooms, barrier isolators and medical rooms. The fog output 4.6 cubic meters per minute with about 20 feet airflow visualization of turbulence in the airflow and around equipment. 3D airflow modeling can be accomplished with this level of fog volume. No airflow contamination is created and no clean is required after visualizing airflow with an ultrapure fog.

The AP32 Ultrapure Fogger provides the highest volume of fog to visualize airflow for periods up to 70 minutes with about 20 feet of visible airflow distance. High purity fog requires no cleanup of any kind after fogging! If visual airflow modeling is needed, the AP32 Ultrapure Fogger is the tool capable of providing 493 ml per minute of fog density, high fog volume with superb visual airflow distance to achieve 3D airflow modeling. - Request a Quote

UltraPure fogger - The AP32 nitrogen fog generator is used in clean rooms, ISO suites and sterile rooms to provide visualization of airflow, flow patterns, dead spaces and turbulence. Nitrogen fog generators support Pharmaceutical guidelines, USP 797 In-Situ Airflow Analysis, ISO 14644-3 Annex B7 guidelines and semiconductor clean room guidelines.

The ultrapure fogger uses liquid nitrogen and De-ionized water or WFI (Water for Injection) to generate a high purity fog with a fog output of 4.6 cubic meters of ultrapure fog per minute for 70 minutes with about 25 feet visible airflow distance, providing more than 322 cubic meters of ultrapure fog. Water for Injection is often used in ISO suites, sterile rooms and clean rooms. Liquid nitrogen is filled into an LN2 dewar, while DI Water is filled into a Stainless Steel chamber. Water is brought to a high temperature and the LN2 boils at room temperature, allowing the vapor from both liquids to form a highly dense, high purity fog. The boiling process creates an ultra pure nitrogen and water vapor. The two vapors then mix together to form a nominal 3 micron vapor droplet at an extremely high fog density of 493 ml per minute. The high purity fog exits at very low pressure, making it buoyant in the airflow. It is highly visible and does not create a disturbance as it enters the airflow. Ultrpure foggers provide the greatest visible distance to visualize airflow, turbulence and patterns. The high fog density is superb to visualize airflow, and when using video, the dense fog is easily tracked in the airflow of a sterile room, clean room or ISO suite. The nitrogen fog generator does not generate any contaminants in the airflow and evaporates back to the same elements we breathe, that being oxygen, nitrogen and hydrogen. Although DI water is quite clean, the LN2 chamber is grounded which helps to add additional purity to the 16 Meg Ohm DI water vapor process. The very high density of ultrapure fog provides superb visualization of airflow, patterns and turbulence. It also has the advantage of providing increased visual distance of the moving airflow. Ultrapure nitrogen foggers create the most pure form of fog that can be used in clean rooms, ISO suites and sterile rooms.

A nitrogen fog generator creates the purest form of fog, particle free, non-contaminating, leaving no contamination or residue behind; thus no cleanup after fog use is required. The ultrapure fog enters the airflow at very low pressure and does not create airflow turbulence. It is CE Mark and compliant to ISO and USP guidelines, and can be used in Class 1 - 100,000 clean rooms for airflow, turbulence visualization, flow balancing and contaminant transport studies. The AP32 ultrapure fogger produces a high volume of fog.
