WHAT IS A CUBIC FOOT OF FOG?
What this means is that the
"manufacturer" of the fog machine has rated their fog machine will produce
"X" amount of cubic feet of fog per minute. But just because one
fog machine claims to produce 5000 cubic per minute doesn't mean that a different machine
that claims only 1000 cubic per minute doesn't actually produce more useable fog. Sound
confusing? The problem is that there are no industry standards on what exactly a cubic
foot of generated fog is, such as what density is the fog in that cubic foot? The numbers
shown in manufacturer descriptions are only useful as a guideline. Your best bet is to
communicate with someone that already owns the fog machine you are considering and ask
them for an opinion.
MUCH FLUID DO FOG MACHINES USE?
This depends on the type of
fog machine, the volume of fog you set it to produce, and the amount of time it is
producing fog. Generally, the smaller machines will use almost a quart of fog fluid every
two to three hours if run almost continuously. Basically, the larger the machine the more
fluid it will use. Check the fluid tank periodically to make sure it always has fluid. If
a fog machine operated without fluid it could be damaged.
Tip: Use a funnel to
replenish the fog fluid
HOW LONG CAN I STORE FOG FLUID?
Generally speaking, if you have left over fog
fluid after Halloween you can store it for use next year. Pour the left over fog fluid
back in it's original bottle (this is were a removable tank on the fog machine really
comes in handy) and close the cap tightly. Store in a cool, dry area away from sunlight.
HOW MUCH WILL THE WIND AFFECT THE
Wind is a fog machines enemy! The particles that
make up the fog are very small, 1 to 2 microns in size, and even a light breeze will
quickly disperse the fog as it shoots from the fog machine. Sometimes you can move your
fog machine to different locations to help redirect the fog to where you want it. Don't
try to aim the fog into the wind, its a losing battle.
HOW DO I MAKE THE FOG STAY LOW TO THE
The fog produced by these machines
comes out hot, and therefore rises in the air. One of the easiest ways to cool down the
temperature of the fog so that it doesn't rise in the air is to build a Fog Chiller. These
are relatively easy and inexpensive to make and make your fog machine much more versatile.

DOES ANY COMPANY
MAKE A FOG CHILLER?
American DJ makes a fog machine/chiller combination called the Mister Kool.

WHAT ABOUT USING EXTENSION CORDS?
If you need to put the fog machine in an area that is
away from a electrical outlet, you'll need to attach it to power via an extension cord.
First, only use a heavy-gauge extension cord rated for outdoor use. Second, try to use a
cord that is no longer than needed. Long cords, particularly light duty ones can lower the
amount of electricity (this called impedance) that gets to the fog machine causing it to
take longer to re-heat, and possibly not put out as much fog. Always position electrical
cords so they won't be tripped over or become a hazard.
