In 2001 cleanroom foggers were developed, and since then, Applied Physics has supported smoke studies and smoke tests using a variety of cleanroom foggers. You can review cleanroom fogger performance for your smoke study. Our CRF5 portable fogger uses 24 ultrasonic piezo devices to produce a pure fog, based on the quality of water used. It is an advanced design fogger in that it controls the water height above the piezo devices in order to produce a maximum amount of fog, whether you have 1 or 2 transducers turned on. Each transducer has 12 ultrasonic piezos, and you can instantly select the number of transducers needed for fog volume at any time. Using the TouchScreen Control, you can simply touch the velocity control for up to 100% fog velocity to tune the fog output to your smoke study requirements. The two 80mm fog outlets allows for single fog hose operation or dual fog hose operation. The CRF5 is very flexible with 12 different accessories, quick fill capabilities, easy fog control, high fog output, and quick drain capabilities.  The CRF5 fogger fills with 11.4 liters and uses to two high output transducers with 20 piezo devices total to produce fog through two 80mm fog outlets. Fog density is 171 ml per minute, which creates about 1.0 cubic meters pure fog per minute during a typical 40 minutes of operation. You can use Deionized water, commonly called DI Water, Sterile water or Water for Injection, known as WFI water to produce a pure fog to visually observe airflow patterns, velocity, turbulence and balance in semiconductor clean rooms, pharmaceutical ISO suites, bio-safety cabinets, barrier isolators, BSC, compound pharmacies and medical rooms. The CRF5 is also used in ISO 3, ISO 5, ISO 7 and ISO 9 suites. The CRF5 provides instant on fog with adjustable fog volume control, and adjustable fog velocity control using two 80mm fog outlets and an array of accessories to match almost any smoke study requirement.

SMOKE STUDY INFORMATION

The CRF5 smoke machine is used in smoke studies as a smoke generator. It is a low cost device providing excellent volumes of fog in support of smoke studies. It is designed with stainless steel for operation in nearly any smoke study. Operation instructions are located on the rear panel, so there is no paper manuals needed in the pharmaceutical ISO suite, sterile room, laboratory or clean room.

Theory of Operation: Ultrasonic cavitation using DI water, Sterile water or Pharmaceutical WFI Water. Use of any other liquid or chemical voids the warranty.

Transducers include a low water interlock and a high temperature interlock during operation. There is also a mechanical water level level sensor that will interrupt the input voltage to the transducer module, should the water level drop to low for operation.
Notes:

1. The fog generated by this device contains microscopic droplets of Deionized, Sterile or WFI (water for Injection) water. AVOID USING IN IMMEDIATE VICINITY OF ELECTRICAL APPLIANCES, WATER SENSITIVE PRODUCTS AND EQUIPMENT.
2. Use the optional Drain and Dry kit is available to drain water and dry the two water cavities prior to CRF5 fogger storage.
3. The CRF5 is intended to be used on a flat surface. Tipping the fogger with water in the reservoir may damage the fogger electronics. DO NOT OVERFILL OR TIP THE FOGGER DURING OPERATION OR DURING DRAIN CYCLE.

Which Cleanroom Fogger or Smoke Generator Is Best For Smoke Studies?

Fogger Technology

The two types of foggers manufactured for use in cleanrooms, ISO suites and sterile rooms are described below.

Ultrapure LN2 Fogger: LN2 foggers use liquid nitrogen and DI Water or WFI water, providing the highest fog volume, highest fog density and best level of fog purity fog. Fog purity is allowing the LN2 to boil, while heating the water. nitrogen and water molecules form and combine at high rates to create a fog vapor. This process removes any bacterial agents and residual particulate matter from the water vapor. The volume of fog produced depends on the version of LN2 fogger purchased. The AP35 Ultrapure Fogger converts 571 ml of water per minute, a high fog density, which generates 5 cubic meters of fog for about 70 minutes to visualize airflow for 20-30 feet. The AP100 LN2 Fogger converts 1520 ml of water per minute, a very high fog density, to produce 15.5 cubic meters of ultrapure fog for about 70 minutes visualizing air flow for about 30-40 feet using 4 fog outputs. The fog is ultrapure leaving minimal, if any, trace particles behind. It evaporates to its gaseous hydrogen, oxygen and nitrogen components, which are natural to the cleanroom environment. LN2 foggers are used in a Class 1 - 10,000 cleanrooms.

DI Water Fogger: This type of fogger has less fog density (less capability to visualize airflow) than the LN2 ultrapure foggers described above. The DI water fog is generated by cavitation in water, producing a water vapor of 8-10 microns in diameter. If the facility manager operates a class 10 to Class 10000 Clean room, the use of a DI Water Fogger poses no problem. However, Cleanroom Metrology Managers in fabs or labs operating at Class 1 to Class 10 performance may desire to use an ultrapure fogger. Although some DI Water foggers are described as ultrapure, unless the DI water is heated or boiled to remove possibility of bacterial agents, the fog is pure based on the quality of water used.
