What is fog?

 

A fog is a suspension of liquid droplets captured in a gas - generally air. Both water-based and oil-based liquids can be made into a fog.

 

Because the size of individual droplets in a fog varies greatly, many people describe a fog by its VMD (volumetric mean diameter, or the size of an "average" droplet). You can also describe a fog qualitatively: dry for (under 15 micron VMD), wet fog (20-40 microns), mist (40-100 microns), and fine spray (above 100 microns).

 

What is a fogger flow rate?

 

A drum mounted fogger set at maximum flow rate of 10 ounces/minute will empty a 55 gallon drum in 704 minutes or 11.7 hours running continuously.

 

A handheld fogger set at maximum flow rate of 10 ounces/minute will empty the 1 gallon reservoir in 12 minutes.

 

What size droplets do you need for your application?

 

Small droplets are light and resist settling, have a long float time, and have a large surface area relative to volume.

 

If you want droplets to diffuse widely, to mix efficiently with a gas, or to avoid wetting, choose a "dry" fog of small particles.

 

For dampening, surface application or particulate settling (dust control), you'd choose a "wet" fog or mist of large droplets.

 

How is a fog created?

 

There are several ways. A natural fog (cloud or ground fog) is formed by condensation of vapor as the temperature drops below the dew point. A thermal fogger heats an oil-based liquid so it can condense in ambient air.

 

Small droplets can also be created by pumping liquid through a small orifice; by slinging liquid from a spinning disk; by ultrasonic excitation; and by turbulent zone atomization.

 

Foggers use a high turbulence vortex air nozzle to atomize liquid into tiny droplets. BioWorld "cold" foggers avoid potential thermal degradation of your chemical, and they work equally well with both water- and oil-based liquids. Also, you can change droplet diameter by adjusting the liquid flow rate.

 

Our nozzles work at low pressures - 2 to 3 pounds per square inch for both air and liquid - have no tiny orifices, and are resistant to nozzle plugging.

 

What is the misting system flow?

 

For good atomization in a misting system, the overall liquid flow rate should be less than 2 ounces per minute.

 

BON should be used at a 1 - 2% dilution in the liquid flow.
