CRF2 and CRF4 Portable Cleanroom Foggers for Smoke Studies
Cleanroom Fogger Performance Comparisons
The CRF4 and CRF2 are portable foggers using DI water, sterile water or WFI water to generate pure fog to visually describe patterns and instability in the airflow for smoke studies of ISO suites, Bio-Safety Cabinets, RAB, medical rooms. The CRF4 and CRF2 support guidelines for USP 797 Pharmaceutical In-situ airflow analysis, Federal Standards 209E and its replacement ISO Standard 14644-3, USP 800 Hazardous Drug Compounding, Airflow Recovery Tests using ISO 14644-3 Annex B12, NSF Standard 49 and National Sanitation Foundation. The CRF4 fogger provides adjustable fog control and higher levels of smoke, where as the CRF2 is a lower cost, smoke generator with a constant fog output. The CRF4 easily out performs other smoke machines designed to look good, but lacking in fog performance. The CRF2 DI Water fogger is for the customer who wants to evaluate fume hoods and airflow hods, glove boxes and similar smaller areas.

Deionized (DI) Water, Sterile Water and Water for Injection (WFI)
Deionized water, commonly referred to as DI water, Sterile Water and Water for Injection or WFI, are used in a DI water Fogger. These tools are often referred to as a smoke machine or smoke generator, and are used in smoke studies of fume hoods, airflow hoods, glove boxes, smaller areas. Because the DI water and WFI water have been purified in one manner or another, the resulting fog is a pure fog used to visualize the patterns of airflow. Although many people use the phrase of smoke machine and smoke study, the pure fog is technically not a smoke, which is composed of particles. The pure fog is a water vapor at 7-10 microns in diameter, at a fog density sufficient to provide a visual understanding of the airflow movement. While the CRF4 fogger produces 5 times more fog, 3 times more fog density and 2 times more visual fog distance, the CRF2 is less expensive. So each of these two smoke machines meet the particular needs of Quality Assurance managers, for either fog volume desired, or low cost desired. DI Water Foggers are used to visualize airflow turbulence, airflow balance and patterns in clean rooms, ISO suites, bio safety cabinets, fume hods, etc. The CRF2 has the operating instructions labeled on the right side of the enclosure, and the left panel provides a convenient water fill view port. DI Water Foggers support ISO 14644-3, Annex B.7 Airflow Direction Test and Visualization; USP 797 Insitu Airflow Analysis and Semi-Standards Clean Room guidelines for airflow visualization and analysis.
Theory of Operation: Ultrasonic cavitation using DI water or WFI water, a pharmaceutical Water for Injection. Use of any other liquids or chemicals will void the warranty.
The transducer is protected from electrical damage when water level is too low. The water level sensor will interrupt the input voltage to the transducer module, when the water level drops too low. This ensures long transducer life and reliability.
Notes:
-
- The fog generated by this smoke generator produces microscopic vapor droplets of water. AVOID USING IN IMMEDIATE VICINITY OF ELECTRICAL APPLIANCES, WATER SENSITIVE PRODUCTS AND EQUIPMENT.
-
- The fan will operate with no water in the reservoir with the power switch in the ON position. This will aid in drying when the chamber is drained.
-
- To increase drain plug tension, remove the plug, rotate clockwise (CW) the front latch while holding the rear metal disk.
