fog machines be the go-to device for
making everything spooky this Halloween
season
but what dark magic lies beneath the
machine to bring you the fog well you're
about to find out because this be the
spooky edition of gadget guts your
average fog machine uses a magical
potion or a bob juice which is typically
made up of glycol in water and is stored
inside the fuel tank the fluid is then
pushed by a high-pressure pump through
the heat exchanger which heats the
liquid and when the vapor moves through
the nozzle and hits the cool air around
you it turns into the magical fog all
right enough of this let's open up this
device to see if there's any buried
treasure inside so there are three major
components to a fog machine the first is
the pump the heat exchange and then the
nozzle first we have the pump which
feeds fluid from the fluid tank all the
way into the heat exchange if you hear
noise during operation it's probably the
sound of the piston pump working if
you're having problems with your fog
machine chances are it has something to
do with the pump here are a few things
to check for if no fog is coming from
the machine check the fluid in the tank
first if you know you have fog fluid
your machine turns on and you can hear
the humming sounds chances are your
pumps working but your systems clogged
so consider running distilled white
vinegar through the system to clear any
blockages and then check to see if your
hoses are kinked because that could be
causing a problem as well if the fogger
power is on but does nothing else your
fuse may have shorted out or you need to
replace the entire pump now here's where
the real magic happens the heat
exchanger turns the fog liquid into fog
vapor essentially the heat exchanger is
a block of metal with the heating
element built into it the temperature of
the block is regulated by a thermostat
and a channel inside the metal block
allows the fluid to travel through it
and into the nozzle the watt is used to
heat the exchanger is a specification
most manufacturers used to describe how
powerful their fog machines are most
wattage ratings of fog machines will be
between 400 to 1300 watts foggers with
higher wattage offer more power to the
system meaning the fogger has to do less
work to maintain the temperature in the
heat exchanger and the final component
is the nozzle as the fog fluid is
through the heat exchanger it's then
superheated and then immediately forced
under high pressure through a tiny hole
in the exit nozzle at the front when the
hot vapor comes into contact with the
cooler air around you it instantly turns
into what we see as fog the nozzle and
it's protective cover will become very
hot during use so be sure to let it cool
down before attempting any repairs I
hope you found this video helpful and
hopefully it saved you some doubloons
comment below with what device you'd
like to see next on gadgets please don't
say a turkey and I'll see you next time
happy haunting
