What Is a CO2 Jet Cannon?

A CO2 jet cannon is specifically used to describe a CO2 special effect apparatus that outputs liquid CO2 from a manual or electric valve, producing an effect called cryo effects, or CryoFX for short.

A lot of discussions have been done regarding the exact names of certain items, and there’s been plenty of disagreements about whether or not these names apply only to specific brands or models or can be used in general terms. One of these terms or phrases is carbon dioxide jet cannon, or “CO2 jet cannon” for short.

Let's throw something confusing your way, but with good intent, as we will clear this up further along. When you search for this “CO2 Jet Cannon” special effect, you will see some phrases online come up that ask the following:

  • What is a CO2 cryogenic fog cannon?
  • What is a cryogenic CO2 jet?
  • What is a CO2 jet cannon?

So, you may ask, “What is a CO2 jet cannon?” In the special effects industry, many different names are used to identify similar products or items. The handheld cryo gun is one of them. Names such as CO2 gun, Cryo Cannon, CO2 Cannon, CO2 Cannon, Cryo Pistol, and handheld CO2 Jet have been used to call these items. Different spellings have been used for these, such as Cryo Canon and CO2 Canon, using only one “n” instead of two, even though this is the incorrect way to spell “cannon.”

One can get easily confused with spelling as well as the questions asked. Well, it gets confusing with all the different names used for the same thing. However, despite the many names used to call a specific product or item, the term “CO2 jet cannon” is specifically used to describe an effective apparatus that outputs liquid CO2 from a manual or electric valve. It’s most often referred to as a special effects product used as part of a discotheque or nightclub.

The CO2 jet cannon uses carbon dioxide gas to propel confetti within the dance area of a nightclub. CO2, which is short for Carbon Dioxide, is a naturally occurring, colorless, and odorless gas. It is a chemical compound that is vital to life on Earth. Carbon dioxide can be compressed in liquid form at high pressures, usually stored in metal cylinders. 

So, What is a CO2 Jet Cannon?

A CO2 Jet Cannon is a device that uses compressed CO2 gas to produce a powerful blast of air, creating a visually impressive effect in entertainment and special events. 

These cannons are widely used in concerts, nightclubs, and other large gatherings, as they create a thrilling, eye-catching spectacle that can add excitement to any event.

How Does a CO2 Jet Cannon Typically Work?

A CO2 Jet Cannon consists of a pressure tank filled with compressed CO2 gas, a nozzle, and a control system. The compressed CO2 gas is released from the pressure tank through the nozzle, creating a blast of air that can reach several meters in height. The control system allows the operator to regulate the intensity and duration of the blast, giving them the ability to create a range of different effects.

In addition to the visual impact, CO2 Jet Cannons also produce a distinctive and dramatic sound that can add to the excitement of the event. The sound is created by the rapid expansion of the CO2 gas as it leaves the nozzle, creating a loud and powerful blast.

What Are the Safety Precautions Needed to Employ a CO2 Jet Cannon? 

While CO2 Jet Cannons are safe to use when handled properly, they must be treated with care and respect. The compressed CO2 gas is stored under high pressure, making it important to take proper safety precautions when handling the tanks. Before use, it is important to check the tank for any damage or leaks, and to ensure that the nozzle is pointed in a safe direction.

In addition to the safety precautions associated with handling the tank itself, it is also important to consider the environmental impact of the CO2 Jet Cannon. CO2 is a greenhouse gas that contributes to global warming, so it is important to use the cannon responsibly and minimize its impact on the environment.

What Are Some Uses for Carbon Dioxide and CO2 CryoGenic Fog Cannons?

Many industries use carbon dioxide in their daily applications, including the food, oil, and chemical industries. While it has many varied commercial uses, its most significant use as a chemical is in the production of beverages, such as soft drinks, which use a lot of carbonation. Carbon dioxide gives the “fizz” beverages known for such as sodas, beer, and sparkling wine. Recently, carbon dioxide has become very useful in the entertainment industry through CO2 jet cannons or CO2 cryogenic fog cannons.

The device employs a valve system with specially engineered tubes where liquid carbon dioxide passes. These are attached to high-pressure cylinders containing carbon dioxide. These high-pressure CO2 cylinders are attached to a siphon tube or dip tube, which allows the liquid to be released from the cylinder.

It is essential to ensure that all the components are correctly attached and securely to a firm surface. The most ideal for this is the ground or floor because the cylinders are cumbersome and will definitely hurt and injure someone when it falls accidentally on a person. The CO2 cylinders should be securely placed close to the CO2 jet cannon. When the cylinder and CO2 jet cannon are firmly and safely installed, a CGA320 adapter connects a special high-pressure hose to the CO2 cylinder. When that is done, the other end of the high-pressure hose is attached to the inlet port of the CO2 jet cannon. The whole thing is then attached to a power control unit so that the operator can regulate the pressure and amount of carbon dioxide released. When the CO2 jet receives a command from the control unit to release carbon dioxide, it opens a valve and allows the liquid CO2 to travel through the specific nozzles and react with the surrounding air.

Once the carbon dioxide is released, it reacts to the ambient air and rapidly expands. The effect produced by this device is stunning, dense, white fog clouds. Over time, other uses were found for the CO2 jet cannon, such as throwing t-shirts or other merchandise to the audience in a sports arena.

Because the term “cryo gun” (used to refer to a device that freezes a body part by spraying a shot of liquid carbon dioxide onto it) came from the medical field, it would then follow that people may ask, “what is a CO2 cryogenic fog cannon?”, as they would relate the word “cryogenic” to the process of freezing abnormal or diseased tissue to destroy them or freezing tissue samples to preserve them for future use or study.

The two are similar in terms of how they work. The only difference is the application of the device. Before long, the special effects industry also began to use the term since they also use a device with the same function. However, the special effects version can spray a higher volume of carbon dioxide out and at more significant pressures.

History of The Phrase "CO2 Jet Cannon"

Over the years, as the CO2 jet cannon started making a name for itself in the special effects business, interested customers, especially those from other countries, started searching for suppliers online. Since people from other countries called it a different name, “cryo gun” was not always used, so the item was pretty hard to look for. Over time, slang progressed; terms got mixed up, and before long, a simple two-word phrase transformed into so many other names. The searches broadened and even included the usage and venues used. Terms like “Cryo Cannon,” “CO2 Cannon”, and “CO2 Cannon” have been used. Sometimes these questions get intermixed:

  • What is a CO2 cryogenic fog cannon?
  • What is a cryogenic CO2 jet?
  • What is a CO2 jet cannon?

When people start asking, “What is a CO2 jet cannon?” or “What is a CO2 cryogenic fog cannon?” they begin to see results but will get confused that these questions may pertain to different products. Let's set the playing field clear. They are all the same product here.

Regardless of what you call it, there needs to be more clarity with the names of CO2 cryogenic fog cannons as CO2 special effects products. It gets even more confusing when you consider the settings they are used in, the type, and the massive number of different products and brands. We hope we’ve cleared up any confusion, and we certainly hope you know the spelling differences. You can also expect to find so many similar items, but the bottom line is that CO2 jet cannon is the primary term for the nightclub special effect.

In Conclusion
