Portable Smoke Studies Fogger for Fume Hoods and Airflow Hoods. Find the highest quality AFM Cube smoke study fogger. Request a quote for our smoke studies fogger used in sterile rooms for visualization studies of airflow turbulence. The portable smoke study fogger is used in smoke studies with DI Water (De-ionized water), Sterile water or WFI (Water for Injection) water to generate about 0.5 cubic meters of fog per minute.
The AFM Cube is a low cost, ultrasonic fogger that operates for a typical 45 minutes per water fill cycle. The AFM Cube fogger provides adjustable fog volume and adjustable f0og velocity, thus the fog volume is adjustable to a variety of air flow monitoring and smoke study requirements. It also has optional remote control of fog velocity and volume via optional wireless control. The fog vapor is composed of water droplets that are about 8-10 microns in diameter; thus as the fog vapor travels thru the airflow, it begins to evaporate. The visual fog evaporates after about 8-9 feet.
No particle contaminants are created or left in the airflow. No cleanup is required other than a general wipe down of pure moisture. And the fog is composed of the same elements that we breathe, so walking thru a fog in your smoke studies is nearly identical to fog encountered in weather. Ultrasonic foggers use de-ionized water, sterile water or water for injection; thus the water is quite pure. The fog can easily visualize turbulence and airflow patterns in Fume Hoods, Airflow Hoods or small Glovebox. Balance of air pressure can be visually described between two clean areas, such as a barrier isolator and sterile room. Bio-safety cabinets and glove boxes can be tested for proper airflow.

Smoke Studies Fogger, AFM40
The AFM Cube Airflow Monitor used in Smoke Studies for Airflow Visualization Studies for airflow visualization studies, airflow monitoring and clean room smoke studies in small area environments. This small, portable, easy to use smoke machine will support your requirements to test airflow in fume hoods, airflow hoods, small glove boxes and similar sized volumetric areas to visually describe airflow patterns, airflow turbulence or uniformity in controlled air flows.
Most Engineers and technicians in the pharmaceutical industry use testing guidelines, such as ISO 14644-3, Annex B.7 Airflow Direction Test and Visualization. Another guideline is USP 797 Insitu Airflow Analysis. Semiconductor companies are now starting to use the same ISO 14644 guidelines for smoke studies and airflow monitor tests. The AFM Cube is used in Smoke Studies and can be used to evaluate how fast a clean room or ISO room recovers from a particle challenge, as guided by ISO 14644-3, Annex B12 Airflow Recovery Test.
Polystyrene latex spheres are typically used specific size peaks of 0.5 micron, 1 micron or 2 microns. The AFM Cube ultrasonic Fogger is used to create the aerosol particle challenge into the sterile room or ISO suite, then air particle counters are used to monitor how quickly the cleanroom or ISO Room returns to normal after introduction of the particle challenge.
Ultrasonic DI Water foggers can be easily compared in fog performance per dollar cost by calculating the actual fog density over time!
Ultrasonic foggers are normally built with 8 to 40 piezo devices. The AFM Cube uses 20 high performance piezos generating a paper white fog density and up to 0.8 cubic meters of fog per minute through a single 80mm fog outlet. As a comparison the AFM40 uses 40 high performance piezos providing up to 2 cubic meters of pure fog per minute through dual 80mm fog outlets.
The AFM Cube fog travels about 8-9 feet in a typical cle3anroom, barrier isolator or BSC operating with a typical airflow velocity of 70 fpm with a typical humidity of 40%. The AFM40 fog travels a typical 12-15 feet using dual 80mm fog outlets. The AFM Cube, as well as the AFM40 provide a dense fog, but the AFM Cube is for smaller fog applications, such as Airflow hoods, while the AFM40 would be used for large barrier isolators, large BSCs and small cleanrooms. Both foggers offer fog volume and fog velocity controls. As the fog travels through the airflow, it gradually evaporates to the same air we breathe, making the fog quite safe to work in.

INFORMATION
The Smoke Studies Fogger is often called a smoke generator or smoke machine by technicians. Although often referred to as a smoke generator, the output is a pure fog and does not require any cleanup after use. Operating instructions are noted on the right panel of enclosure.
Theory of Operation: Ultrasonic piezos operating about 1.5MHz to 1.7MHz using DI water or Pharmaceutical WFI Water. Use of any other liquids or chemicals will void the warranty.
The transducer life is up to 1000 hours depending on liquids used. the ultrasonic device is protected from overheating by using a water level interlock to shut power off to the ultrasonic transducer in a low water condition. The water level sensor will interrupt the input voltage to the transducer module, should the water level drop to a low level. This ensures long life and reliability of the transducer.
Applications and Maintenance
- The Cleanroom Fogger used in Smoke Studies should not be used around live electrical operation.
- After a smoke study is completed, drain all the water using the Drain Plug of AFM Cube. Optional Air Drier is provided to speed up the evaporation of all water in the water cavity, after a smoke study is completed.
- It is important to evaporate all water in the water cavity so as to prevent algae from growing in the water cavity when water is left in the cavity.
- The Smoke Studies Fogger fogger is intended to be used on a flat surface, on its feet. Tipping the fogger with water in the reservoir will damage the fogger. The Smoke Study Fogger is meant to operate with a prescribed level of water fill. If you overfill, no fog will be produced. If you underfill, the piezos may not turn on due to low water condition. Read the Instructions before operation!
- Always operate electrical products in a safe manner. The Smoke Study Fogger emits a humid mist, and therefore should not be used in or around electrical operating systems.
Portable Fogger, AFM Cube Clean Room Fogger used as Airflow Monitor in Smoke Studies
The AFM Cube provides portability and can be carried using the single carry handle. While carrying the fogger, the water cavity should be empty. Should you need to move the fogger on a table with water in the water cavity, gently mover the fogger with slow movements, so that water does not splash inside the fogger.
Airflow Visualization Considerations
Nitrogen-DI-Water Foggers provide a very dense, paper white visible fog, Liquid Nitrogen vapor is combined with water vapor to form the clean fog, typically a 45 minutes operation. The fog output is adjustable in velocity and amount of fog released, controlled by a mechanical liquid nitrogen valve, and a touchpad to adjust speed of fog output. Wireless Controls using FOB is also available. The Apollo 35, Apollo 50, Apollo 100 and Apollo 150 Nitrogen-DI-Water Foggers are demonstrated in the Sistema Lab, and all ship from Germany direct to your dock.
* Use protective Hand Gloves, Face shield and smock when handling Liquid Nitrogen, and always follow your local safety guidelines when handling liquid nitrogen
Use DI Water, Sterile Water or WFI Water
AFM Cube Cleanroom Fogger used as airflow monitor in Smoke Studies produces about 0.8 cubic meters fog/minute at 80 ml fog density with 8-9 feet visible fog, using Di Water, Sterile Water or Water for Injection. Typical operation time is about 40-45 minutes typical operation. You can refill and restart with 40 F water temperature.
AFM40 Fogger used in larger smoke studies produces 2.0 cubic meters fog/minute providing about 12-15 feet of fog viewing, using Sterile water, DI Water or WFI Water. Typical operation is about 40 minutes, and you can refill with 40F water and restart. Adjustable fog volume and adjustable airflow is controlled via touch pad buttons or wireless Key Fobs and remote control.
