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.
