Applied Physics USA Portable cleanroom fogger provided since 2001 for airflow visualization in smoke studies of clean rooms, ISO suites, sterile rooms, barrier isolators and glove boxes. Compare clean room fogger performance for your smoke study. In 2001 portable cleanroom foggers used LN2 and deionized (DI) water to provide a dense constant fog output. Our modern ultrapure foggers include adjustable airflow control, adjustable fog volume and wireless remote control using LN2 and WFI water, DI Water or sterile water. Our LN2 ultrapure fogger includes a rolling trolley, replacing traditional carry handles of the older ln2 fogger. The AP35 and AP100 LN2 ultrapure foggers are the best tools for ultrapure fog and fog volume control with user friendly operation. Both combine LN2 with DI water, sterile water or WFI water vapor to produce high volumes of ultrapure fog. We also provide the lower cost, lower fog volume CRF2 and CRF4, portable foggers; both which use ultrasonic transducers to produce a pure fog for airflow visualization of turbulence in fume hoods ISO suites, sterile rooms, and to balance airflow between rooms and door openings. The CRF4 Cleanroom Fogger is provided with an electro-polished, stainless steel enclosure and is by far our best selling fogger due to its small size, adjustable fog volume, adjustable airflow and wireless remote control. It uses only DI water, sterile water or WFI water to produce an adjustable fog output that can be tuned to your dynamic airflow needs. Our Dry Foggers and portable, battery operated, Backpack Dry Fogger is used to sanitize rooms, buildings, tunnels, foods, food processing and agricultural growths by killing molds, yeasts, fungii, spores, coronavirus, Candida Auris fungus, a harmful form of yeast and similar types of harmful bio-growths, harmful to edible plants, humans and animals.

The PBF-48 Portable Backpack Fogger is quite capable of sanitizing rooms and offices using an “All Natural” sterilant, which is capable of killing viruses, coronavirus, spores, molds and fungii on contact. It is most often set up with a 30 micron fog output to support agricultural plant and tree leaf applications; or can be set up with a 50 micron spray for surface contact killing of critical unwanted bio-organisms in plant life, such as killing a harmful banana fungus in South America called Tropical Race 4, TP4. Other fogging uses are to mitigate Hoof and Mouth Disease in milk cattle, and safely killing unwanted plant and tree leaf pathogens.

CO2 Fogger uses deionized, sterilized or WFI water combined with CO2 Ice to provide a dense fog to video airflow and turbulence about 4 to 6 feet during the first few minutes, but decreases in fog volume over an 8 minute period. A CO2 fogger produces excellent fog for first several minutes to video smoke studies and describe airflow, patterns and turbulence in Pharmaceutical ISO suites guided by USP 797 Pharmaceutical In-Situ Airflow Analysis. As the CO2 ice evaporates, the fog volume decreases to zero. CRF2 has replaced the CO2 Fogger as of 15 April 2021.
