The AP35 Ultrapure LN2 Fogger provides superb fog volume, fog density and longest visual airflow today. The AP100 Ultrapure Fogger is the only fogger in the world today producing more fog than the AP35. See performance comparison below. The AP35 uses liquid nitrogen and DI water, sterilized water or water for injection (WFI) to produce a dense, ultrapure fog density at ~ 571 ml per minute to visualize airflow, air patterns, direction, turbulence, dead zones and airflow velocity for ~ 70 minutes in clean rooms, ISO suites, sterile rooms, barrier isolators and medical rooms. The fog output is ~ 5 cubic meters per minute with ~ 20-30 feet of visual fog to locate turbulence in the airflow and around equipment. 3D airflow modeling and video modeling can be accomplished with this level of fog volume. No airflow contamination is created and no clean is required after visualizing airflow with this ultrapure smoke generator.

UltraPure fogger - The AP35 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 and ISO guidelines, such as USP 797 In-Situ Airflow Analysis, ISO 14644-3 Annex B7 guidelines. The semiconductor clean room guidelines of Federal Standards 209E is also supported, which was recently replaced by ISO Standard 1446, which is also supported. Cleanroom fogger performance is compared below between ultrasonic foggers and ultrapure foggers. Fog volume, fog density, visual fog distance is the most important parameters, along with cost. 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 ~ 5.0 cubic meters of ultrapure fog per minute for ~ 70 minutes providing ~ 20-30 feet visible airflow distance, providing high volumes of ultrapure fog for larger clean rooms. Water for Injection is often used in ISO suites, sterile rooms and clean rooms. Liquid nitrogen is filled into an LN2 dewar, while DI or WFI 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 combine and form a highly dense, ultrapure fog at 2 to 3 micron diameter and high fog density. The high purity fog exits at very low pressure, making it buoyant in the airflow. Take a look below at the performance of the different foggers to understand what the capabilities of the different foggers. 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 AP35 ultrapure fogger produces a high volume of fog to visualize airflow and turbulence in clean rooms, sterile rooms and ISO rooms. |
