In 2001 portable cleanroom foggers were introduced using LN2 and DI Water for smoke studies. The AP35 is the latest ultrapure cleanroom fogger which includes adjustable airflow control, adjustable fog volume, wireless remote control and 9 effective accessories. Clean room foggers support smoke studies for airflow visualization and characterization of clean rooms, medical rooms, ISO suites, sterile rooms, barrier isolators, glove boxes, airflow hoods and fume hoods. Cleanroom ultrapure fogger, LN2 fogger, cleanroom fogger, portable fogger, DI water fogger and CO2 foggers, are also called smoke machines, and are used in smoke studies and air flow characterization of clean rooms, ISO suites, sterile rooms, fume hoods, bio safety cabinets and medical operating rooms. The portable fogger is available for smoke studies in clean rooms, ISO suites, barrier Isolators, glove boxes and sterile rooms.

In 2001 portable cleanroom fogger was developed to use LN2 and DI water to produce about 1.5 cubic meters of fog per minute to visualize airflow turbulence. The new AP35 LN2 portable ultrapure fogger produces 5 cubic meters ultrapure fog per minute, and adds a rolling trolley, adjustable fog controls and wireless remote control. The AP35 produces the same type of ultrapure fog, but 3X more than the portable foggers designed in 2001. It uses 35 Liters LN2 and 5 Liters of De-ionized water, sterile water or WFI water. The AP35 can visualize airflow turbulence and balance airflow between rooms. Ultrapure fog is generated by heating water to form water vapor, and then mixing the water vapor with a nitrogen vapor forming a 2-3 micron diameter fog vapor. LN2 readily boils at room temperatures, producing high volume of nitrogen vapor. The LN2 fogger in 2001 was a mechanical tool with no adjustable controls, which has not changed much since then. The ultrapure fogger today functions in a similar manner as described above, but allows for adjusting the fog volume and airflow velocity, as well as providing wireless remote control. The AP35 Ultrapure Fogger produces 3.5X more ultrapure fog than previous ln2 foggers used in smoke studies and airflow characterization in clean rooms, ISO suites, medical operating rooms, sterile rooms and medical rooms. Ultrapure LN2 foggers provide the highest purity of fog, the highest volume of fog, the highest fog density; all of which combines to provide the longest visual airflow distance. The AP35 LN2 fogger provides about 5 cubic meters of ultrapure fog per minute for up to 70 minutes with 571 ml per minute fog density, providing 20-30 feet of visual airflow using 1 or 2 fog hose outputs. The fog volume can be adjusted between 2 cubic meters and 5 cubic meters per minute. It is the fog density of a fogger that controls the distance of the visual air flow. The higher the fog density, the more visual fog distance is provided, and our AP35 provides 2 times more fog density than similar LN2 ultrapure foggers. No other ultrapure fog generator is capable of this fog volume, yet the AP35 costs nearly the same as other ultrapure fog generators. Our AP100 LN2 Fogger produces 15.5 cubic meters a minute of ultrapure fog and provides four 5Mx80mm fog hose outputs. If you do not want to use LN2, but want high volume fog, consider the CRF4 Cleanroom Fogger. The CRF4 provides about 1.25 cubic meters of pure fog per minute for 40 minutes with 187 ml per minute fog density, providing 10-15 feet of visual airflow. It provides an adjustable fog volume and airflow velocity, touch pad control and wireless remote control. Alternatively, we provide our CRF2 DI Water Fogger for low cost solutions to provide airflow visualization in fume hoods, Bio-Safety Cabinets and Aseptic Isolators. Our foggers are priced according to fog volume produced. 

Deionized water (DI water), sterile water or water for injection (WFI) is combined with liquid nitrogen in the AP35 Ultrapure Fogger to produce 571 ml per minute of fog density. Applied Physics discusses fog volume, fog duration, fog density visual flow distances as a metric so that you can compare performance of different fog generators. It does not make sense to buy a smoke generator on cost, if you do not know how much fog it produces or the visual airflow distance provided; or whether it is a fog that requires cleanup afterwards such as use of smoke sticks.  Ultrasonic foggers use Deionized water (Distilled water) or WFI (water for injection), a pure pharmaceutical water. DI water foggers are more simple to operate and produce much less fog and fog density than an ultrapure fogger. Our CRF2 Cleanroom Fogger supports airflow visualization and airflow recovery tests as defined by ISO 14644-3, B12. CRF4 Cleanroom Fogger is ideal for airflow visualization in clean rooms, ISO suites, medical operating rooms and sterile rooms.

AP35 Ultrapure Fogger supports USP 797, ISO 14644-3, Annex B.7, Federal Standards 209E and ISO 1446 for airflow visualization.

The AP35 Ultrapure LN2 Fogger is designed with a 316L Stainless Steel body and enclosure and electro-polish finish. It provides 571 ml fog density per minute with an adjustable fog output from 2-5 cubic meters per minute for up to 70 minutes operation with 20 to 30 feet of visible airflow for smoke studies and 3D airflow modeling. Ultrapure Foggers are used in smoke studies of ISO suites, sterile rooms and clean rooms that require higher volumes of fog, high fog density and long visual airflow distances. Also referred to as LN2 foggers and liquid nitrogen foggers, an ultrapure fogger can visualize airflow, turbulence, patterns, direction and to locate dead airflow zones in Class 1 to Class 100,000 clean rooms. Although the base cost of the AP35 is nearly the same as similar LN2 foggers, The AP35 produces much more fog and fog density for 2X more visual airflow distance.
