How Does a Fog Machine Work?
A fog machine is delicately designed for creating various effects that lead to the perfect situation as one requires. Fog machines contain various fluids and pumps from which the needed residue is generated.
We’ll take a look at each individual functioning part of the fog machine in more detail.
The Fog Machine Fluid
This fog juice is installed inside the fluid tank and made to pass through the heat exchanger with the help of a pressure pump. When this heat exchanger reaches a maximum temperature of 400 degrees, it changes the liquid substance into vapor form. And then this generated vapor is released into the air.
If the vapor is released in a cool atmosphere, it immediately transforms into the opaque aerosol that we know as fog or smoke and which is visible to us.
“ The process which is used to vaporize the fluid juice is known as flashing.”
The Pump plays an essential role in the process of delivering the fog fluid, and is often referred to as the Piston Pump.
which is used to transfer the fluid from the machine tank to the heat exchanger. As the piston works, it creates some noise which confirms the operation has been done as you start the machine. The point to be noted is that you must allow a certain amount of fluid to go to the heat exchanger or else the heat exchanger will stop. This is because the fog juice going through the metal block is excessive.

The point to be noted is that you must allow a certain amount of fluid to go to the heat exchanger, or else the heat exchanger will stop. This is because the fog juice going through the metal block is excessive.
The Heat Exchanger
This part of the fog machine is built like a block metal equipped with a heating element.
You can get either heated or chilled fog machines, each with different purposes.
A thermostat is made inside it which generates and regulates the temperature inside. As the heating of the fog juice is completed, it then flows through the nozzle of the machine as a vapor.
Normally, this type of heating process would produce a strong, pungent smell, but fog machines use a special combination of glycerin and glycol mixed with water to help prevent this.
This fog machine nozzle is designed with a material containing brass. It has some small openings that allow the vapor to be released when high pressure is asserted. This makes the whole nozzle and the opening of the machine to remain hot to the tip and highly inflammable.
It’s important that the nozzle is thoroughly cleaned once you are finished using the fog machine.
To do this, unplug the machine and give it time to cool down completely. Then, check the output nozzle for any excess debris. If there is debris, you can use your fingernail or a sharp object to scrape out the opening of the nozzle.
You could use a small needle or pin to clean out any excess, by moving it around the nozzle in a back and forth motion.
Proper cleaning of the nozzle will ensure a better working fog machine.
What Effects Can It Produce?
Fog Machines are generally used for entertainment purposes, as they can add to the atmosphere and tone of an event. However, they are also used in various military training and industrial applications, so different effects will need to be used.
You can use the fog machine to generate the following effects, depending on the mood and atmosphere you are trying to create:
Smoke: The machine can be used to make smoke effects by using smoke cookies, inflammable substances, and other smoke cartridges.
Fog: This effect from the fog machine can be created by mixing a fog fluid inside a heat exchanger. The substance will be heated until the fluid part of it vaporizes and turns into a thick visible cloud.
Haze: This effect from the fog machine is created by using a fluid named as haze fluid. This haze fluid is used to create an effect like a lightning beam.
Carbon Dioxide: Carbon Dioxide is used to produce a specially designed fog fluid to create a very thick and powerful billowing plume. When this substance is exposed to the air or into the atmosphere, it expands into the vapor to condense the moisture in the air to produce special effects.
Liquid Nitrogen: This substance is heated inside the fog machine to its boiling point which leads into the generation of steam and elevated humidity. When this moisture inside the device condenses, it would create the low lying fog that rolls to the ground.
Dry Ice: The mixture of carbon dioxide and dry ice causes a sublimation that creates gas. This gas is then condensed with water vapor to produce a solid white fog that will provide low lying fog effects.
A fog machine is an excellent tool to help you to create the atmosphere you desire, and after reading our guide of How Does a Fog Machine Work, you can get the party started without any hassle.
It can significantly alter the tone of a show or event, which leads to greater entertainment for the audience. Effects created by a fog machine help to assist you in maintaining the mood or the theme of the event, and without them, the event could feel completely different.
They can help to produce the sensation of being somewhere else, and provide the audience with a greater sense of the overall atmosphere.
We hope this article has helped you to understand what a fog machine is, and how a fog machine works. Now you can start to use these unique machines for your own entertainment or personal use.
