HOW DO FOG
MACHINES MAKE FOG?
Water based fog machines generally use a mixture
of very pure glycol and water as the fog fluid. This fluid is pumped by the machine into a
temperature controlled heat exchanger that vaporizes the fluid into thick clouds of fog,
projecting it out through a nozzle located at the front of the machine. Read our "How they work" section for detailed information.
DO FOG MACHINES MAKE FOG CONTINUOUSLY?
While all fog machines need an initial
warm up period, usually around five minutes, the basic difference between consumer and
high-end professional models is that consumer and semi-professional models usually cannot
sustain a continuous output of fog. They will usually generate fog for a short period,
then need to pause to reheat before they can make fog again. This is a continual cycle
during it's operation.
More expensive models can
generate fog continuously without the reheat cycle in between, but they cost much
more than consumer or even semi-professional models.
HOW IMPORTANT IS THE WATTAGE OF A FOG
The wattage of
the heating element can be a good indicator of how well a fog machine will perform. Most
consumer fog machines generally range from 400 to 1300 watts. With a higher wattage
rating, the fog machine can not only produce more fog, but equally as important it will
not have to go into a re-heat cycle as often because the heat exchanger has more power
WHAT IS A TIMER REMOTE CONTROL AND DO
I NEED ONE?
All fog machines come with some type of
activation device, usually in the form of a simple "single button" remote
control connected to the fog machine via a cable. When you want the fog machine to
generate fog, you hold down the button on the remote control. When you let up on the
button it will stop making fog or it will stop automatically when the fog machine needs to
re-cycle. The problem with this type of remote is that it requires a user to operate it
every time you want more fog.
But there is a solution. Most fog machine
manufacturers have a special remote control available as an optional accessory. The Remote
Timer Controller has a build in timer/volume control (like the one pictured) which
eliminates the need for you to spend precious Halloween time manually operating a fog
These remotes allow you to set the
intervals at which the fog machine will come on, how long that interval will last and the
volume of fog to produce. As an example, the Timer Remote for the Visual Effects brand of
fog machines allows you to set the duration anywhere between 1 and 10 seconds, and the
interval between 10 seconds and 5 minutes. So, you could set the timer to activate the fog
machine every three minutes, with a burst duration of 10 seconds.
When operated in an
enclosed area, such as an indoor Halloween party or haunted garage, you don't need the fog
machine to generate fog as often as you would using it outdoors where the fog will
disperse and dissipate quicker and you have more area to cover. Needless to say, we
consider Timer Remote Controls an absolute must for your fog machines unless you want you
be glued to a remote control all Halloween night!
