UltraPure fogger - The AP35 LN2 fogger is used in clean rooms, sterile rooms and ISO suites providing visualization of airflow, flow patterns, dead spaces and turbulence. Nitrogen fog generators provide a high purity fog to support Pharmaceutical guidelines, USP 797 In-Situ Airflow Analysis, ISO 14644-3 Annex B7 guidelines and Federal Standards 209E in semiconductor clean rooms. It uses a modular design for simple operation and maintenance.
A Nitrogen Fogger uses two sources to produce an ultra pure fog. The process combining the liquid nitrogen and DI water includes boiling the liquid nitrogen and DI water. As the LN2 and DI water boils, the vapor droplets are combined to form the highest purity of fog and highest fog density, which is not matched by any other type of fogger. UltraPure fog provides the greatest visible distance of the airflow turbulence, patterns. The ultrapure fog can easily describe how airflow is balanced in a sterile room or ISO suite. The nitrogen fog generator is sometimes referred to as a smoke machine by facility staff. In fact it does not produce smoke at all, which would be a particulate type of fog. The manner in which the nitrogen fogger produces fog causes DI Water and liquid nitrogen to boil in separate LN2 dewar. The DI water comes to high temperature forming a water vapor composed of vapor droplets less than 2 microns in diameter. Although DI water is quite clean, there is some remaining residue in the DI water. During the DI Water heating process, any remaining residue in the DI water gets attracted to the walls of the DI Water chamber, which is grounded. This helps to provide an ultra pure fog using a typical 16 Meg Ohm Distilled water or WFI water for injection. The water vapor droplets then pass over the Liquid Nitrogen Dewar, where the LN2 boils at room temperature. The resulting combination of water droplet and nitrogen droplet forms an ultrapure fog droplet at a nominal 2-3 micron diameter; which creates a very dense, low pressure, ultra pure fog. The high density of ultra pure fog droplets provides the best visualization of the airflow and turbulence, increases the distance at which one can see the airflow and it is the most pure form of fog that can be used in a cleanroom.
An ultrapure, nitrogen fog generator creates a particle free, non-contaminating, high purity fog, leaving no residue behind as the ultra pure fog evaporates back to the air components that we breathe, nitrogen, oxygen and hydrogen. The fog enters the airflow at very low pressure, thus it does not create a turbulence, making the UltraPure nitrogen fogger the best cleanroom fogger suitable for use in Class 1 - 100,000 clean rooms for airflow, turbulence visualization, flow balancing and contaminant transport studies around process tools. This ultra pure fog is typically used to support USP 797 In-Situ Airflow Analysis in Pharmaceutical sterile rooms, barrier isolators and ISO 1-9 suites.
