GENERAL INFORMATION
The operation instructions are located on the front panel. This is an addendum to those instructions.
Theory of Operation: Ultrasonic cavitation and DI water. Use of any other liquids or chemicals will void the warranty.
The transducer life is ~5,000 hours. To protect them from damage there is a level sensor that will interrupt the input voltage to them should the water level drop to an unsafe level.
Notes:
- The fog generated by this device contains microscopic droplets of DI 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.
- The 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. DO NOT OVERFILL OR TIP THE FOGGER.

CO2 Vapor Fogger, 3cfm - Request a Quote
The Model 5 CO2 Fogger is used to visualize airflow, turbulence and velocity patterns in your cleanrooms.The fog is produced using a 1 lb. block of dry ice placed in a DI water reservoir which has been heated. The Model 5 CO2 Fogger is NOT an “On Demand” fogger. Once the Fog process has started, it will continue to produce fog, 3 cfm at first, then decreasing down to 0 cfm when the dry ice has been consumed. During operation it can be unplugged and carried to the area to be tested. The Optional CO2 Fogger wand is designed to allow the user to select the type of fog dispersed from the wand, e.g., jet fog (left photo) or curtain fog (right photo). Simply sliding the end of the wand will select the desired fog pattern.
Features
- The Model 5 CO2 Fogger is a multipurpose analytical tool for visually monitoring airflow characteristics in cleanrooms and other spaces.
- The unique wand allows three different fog patterns to be generated: curtain fog, cloud fog and jet fog. No other fogger has this feature.
- Compact: Less than one cubic foot in size.
- Portable: Easily carried into the tightest spaces to perform airflow tests.
- Weight: About 26 lbs. (57.2 KG) with water and dry ice.
- Can be used in the Class 100 - Class 10,000 spaces.
Applications
- Cleanroom laminar flow tests
- Airflow balancing
- Wet bench exhaust optimization
- Chemical process equipment ventilation tests
- Personnel safety exhaust verification
- Pressure balancing between rooms and spaces
- Leak detection in ducts
CO2 Vapor Fogger FAQs
- The CO2 Fogger works on the principle of combining dry ice (solid carbon dioxide) with heated, ultra-pure (DI) water in a hard anodized heating chamber to produce a non-contaminating fog. The fogger is protected by over-temperature sensors and can be run dry without harming the equipment.
- CO2 in normal (lack of high heat) conditions is stable, inert and non-toxic.
- The average atmosphere, including cleanrooms, contains ~3.3% CO2.
- The average person exhales 5.5% CO2.
- The CO2 used in the Fogger is the same CO2. It is not in particle form. There are no carbon particles, nor any residue left from contact with the vapor.
- Liquid CO2 as used in our dry ice block maker can be purchased as pure as 0.98%.
- CO2 is used in many specialized ultra-pure cleaning applications in the semiconductor and other industries in a “snow “ form.
- No, disinfectants or other additives cannot be added to the water.
- No, this fogger is not intended to eliminate insects or pests.

Fogger Technology
The three types of foggers manufactured for use in the semiconductor and pharmaceutical industry are described below.
Ultrapure Fogger: This type of fogger produced by MSP provides the highest volume, density and purity of fog. Purity is created by bringing the water to a boil, creating a vapor, while simultaneously using gravity to remove the residual mass from the vapor. This process removes any bacterial agents and residual particulate matter from the vapor. The pure vapor is then passed over an LN2 bath, which naturally boils at room temperature. The water molecules quickly attach to the nitrogen molecules (quenching process), creating a nominal 3um fog droplet. The volume of water and nitrogen molecules that combine is extremely high in quantity, creating a dense, high volume, ultrapure fog output with exit temperatures of about 80 degrees F with an exit pressure of less than 0.5 lbs, so as not to disturb the surrounding airflow. 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. The high density of the fog increases the duration and travel distance of the fog. This fogger can be used in a Class 1 - 10,000 Cleanroom environment.
DI Water Fogger: This type of fogger has less fog density (less capability to visualize airflow) than the UltraPure Fogger described above, but more density than the CO2 fogger described below. The DI water fog is generated by atomizing DI water into water droplets, which are nominally 10um in size. The water droplets contain residual particulate matter from the DI water, and when the water droplet evaporates in the Cleanroom, the particulate matter remains as a “haze particle 10nm to 100nm in diameter” adrift in the air currents. If the facility manager operates a class 10000 (or worse) Cleanroom, the use of this fogger poses no problem. However, Cleanroom Engineers who manage facilities operating at Class 1 to Class 1000 performance should not use DI water fog, since the resulting Haze particles have a potential to affect the semiconductor yield or the pharmaceutical drug process. Although some DI Water foggers are described as ultrapure, unless the DI water is vaporized to remove bacterial agents and residual particulate matter, the fog is not ultrapure. The 3-5lb output pressure of a DI water fogger also distorts the airflow patterns, thus adding to the turbulence. The temperature output is typically less than the surrounding room temperature, thus a fog generated from the atomized water droplets will sink in a typical 70 degree room temperature. This fogger can be used in a Class 10 - 10,000 Cleanroom environment.
CO2 Fogger: This type of fogger is designed for low volume, non-process critical applications such as bench airflow testing. The fog is created using CO2 ice as the fogging agent. The fog contains elements of the CO2 and the user must determine if the residual CO2 components are acceptable in a process environment operating Class 100 to Class 10,000. The 3-5lb output pressure of a CO2 fogger also distorts the airflow patterns, thus adding to the turbulence. The output starts at about 3cfm and slowly decreases to 0 CFM in about 10 - 12 minutes.
