The fog machine is responsible for spectacular effects such as beams of lightning cutting through the venue to set the mood.
A fog machine is a gadget that is usually utilized by professionals in the entertainment business to create artificial dense vapors that look and act like fog.
It uses one of three approaches to simulate the visual illusion of fog or smoke, each with its own set of pros and downsides. They can employ hot glycol and water, atomize fluids into the air, or use dry ice to do this.
These machines are typically employed to create cinematic effects, stage show effects, and occasionally Halloween or other small-scale presentations.
How does it perform?
The fog machine fluid, also known as fog juice, is placed inside the fluid tank and expected to run through the heat exchanger using a pressure pump.
The liquid ingredient is reduced to vapor when the heat exchanger reaches a maximum temperature of 400 degrees Fahrenheit. This vapor is transported via the machine’s nozzle and released into the air.
When this released vapor comes into contact with the chilly environment, it turns into the opaque aerosol we know as fog or smoke, which is visible to us. The process of vaporizing fog machine fluid is commonly referred to as “flashing.”
As a result, make certain that the fog juice you’re using is the one recommended for your equipment.
Each fog machine has its own set of fluids that enable it to function properly. If you ignore this warning and use fog juice nevertheless, you will almost certainly get a low-quality fog that is potentially damaging or dangerous to the equipment.
The fog machine pump is an integral part of the fog fluid delivery process. It’s also known as the piston pump, and it’s responsible for transferring fog juice from the machine tank to a heat exchanger.
When the piston pump is running, you’ll hear a distinct noise coming from the piston to ensure that it’s working. Make sure the pump does not release the fluid too quickly; otherwise the heater will shut off quickly. This is due to an excessive amount of fluid passing through the metal block.
2. The Heat exchanger (transfers heat)
The heating element is installed in this component, which is built like a block metal. It has a thermostat built in that controls the temperature inside. When the fluid has finished heating, it becomes a vapor and passes through the fog machine’s nozzle.
3. The Nozzle is a type of device that is used
Brass is used to construct the fog machine nozzle. When high pressure is applied, it has small gaps that allow vapor to escape. As a result, the nozzle and its opening remain extremely hot to the touch and combustible.
- The fog machine includes a one-button remote control that makes operation easier. When you want to discharge the fog into the atmosphere, you normally click the button on the remote control down.
- It’s best to utilize a remote control with timer settings so you can regulate when the fog is released. The fog machine remote control may be used to determine the amount of fog you want to emit and how long it will stay.
The fog machine can be used to generate unusual atmospheric effects for television shows, film productions, concerts, amusement parks, theaters, nightclubs, video arcades, and other similar entertainment events.
In reality, if you want to create mid-air laser visible effects that you can employ to establish the mood and engage your audience, a fog machine is a must-have.
Fog Machine Vapors’ Damaging Effects
Smoke has been utilized for ambiance or to heighten the visual impact of lighting effects in movies, theater productions, and concerts. This fog is produced by fog machines and is not made up of water vapor.
Glycol is the main component in theater smoke. Glycol is found in a variety of products, including antifreeze for automobiles, and can be dangerous if consumed or inhaled by humans. As a result, the effects of fog machine vapors are questioned.
1. Lung Limitation
The lungs’ ability to expand and hold oxygen can be harmed by exposure to theatrical smoke. As the fog enters the lungs, it irritates the lining, making deep breathing difficult. Opera singers, who rely on the ability to hold vast stores of air in their lungs to perform, are particularly vulnerable.
Other possible negative effects of exposure to theater fog include dizziness, shortness of breath, chronic headaches, and chronic weariness. The body begins to run out of oxygen as the glycol inhibits the body’s ability to take in air. When the body is depleted of oxygen, it starts to run down and exhibit these signs.
The fog is made by machinery that hangs in the air or rises; dry ice fog is chilly and sinks to the ground. While this may be appropriate in some cases, it is generally regarded as inferior to more professional devices, and dry ice is typically used only at home or by individuals on a budget.
