Everything about fogging machine: Working, components, types, and uses

Generally, a fogging machine is used to apply or spray certain chemicals in a fine mist. It is also utilized for fumigation, sanitization, insect control, and odor removal. Molds can also be removed using these machines. They are also called fog generators or smoke machines.

A fogger, unlike conventional spraying equipment, delivers the chemical as fog (or smoke). This is the most effective approach to apply or spray certain chemicals. Furthermore, spraying chemicals in this manner allows them to reach areas where other types of spray fail to reach.

The fogging machines are widely used by disaster responders, crime scene investigators, clean-up crews, food processors, laboratories, and others. It is frequently used in situations where the working environment must be sterilized, and cleanliness must be maintained regularly.

How does a fogging machine work?

The disinfectant or chemical liquid administered through a fogging machine sanitizes both surfaces and the air itself. The micro-droplets of disinfectant or chemical solution remain on surfaces for a longer period, giving long-term protection.

The fogger works by applying pressure to create a fine mist (or fog) that is applied to the desired area, with the spray density being controlled by a manual valve for the best results. The thin fog can penetrate smaller and hidden surfaces and even reach into corners and difficult regions.

Components of a fog machine:

The following components are required for a fog machine to function correctly:

  • The fog machine fluid

With the help of a pressure pump, this fluid, also known as fog juice, is put within the fluid tank and forced to travel through the heat exchanger. The liquid substance 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 atmosphere. When this released vapor comes into contact with the cool 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."

  • The pump:

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 will hear a distinct noise coming from the piston to ensure that it is working. Ensure 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.

  • The heat exchanger:

The machine has a heating element and a built-in thermostat that controls the temperature inside. When the fluid has finished heating, it becomes a vapor and passes through the fog machine's nozzle.

  • The nozzle:

The fog machine has a high-quality nozzle made of brass. 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 remote control:

The fog machine comes with a one-button remote control that makes it easier to operate. When you want to release the fog into the atmosphere, you usually press the button on the remote control.

It is best to utilize a remote control with timer settings since this will allow you to choose the best time for the fog to be released. The fog machine remote control may be used to determine the exact amount of fog you want to emit and how long it will stay.

What is the use of a fogging machine?

Following the COVID-19 outbreak, fogging machines have become a crucial piece of equipment for properly sanitizing vast internal spaces, common contact surfaces, and hard-to-reach places.

This procedure is more cost-effective than traditional cleaning because of its speed and capabilities, and it doesn't require any furniture or equipment to be relocated in order for the treatment to work.

They can be used in various settings, including offices, waiting areas, classrooms, gyms, vacation homes, and retail malls. They're especially popular among public transportation firms and car rental companies for disinfecting cars when they return to base or after each hire

What should you put in a fogging machine?

We highly recommend you to use an antiviral disinfectant and sanitizer that has been proven to be effective against viruses and other hazardous microorganisms. Disinfectants based on BAC, DDAC, and Hypochlorous Acid (HOCI), which have been carefully studied and confirmed to successfully kill a wide range of bacteria and viruses, including Covid-19, are the best to use.

Types of fogging machines:

Many novel approaches to clean and disinfect have evolved due to the pandemic, making it difficult to determine which product is genuinely effective and how they operate. However, two items have become more mainstream and are utilized by a wide range of sectors and businesses of all kinds.

  • Thermal fogging machine:

They use heat to evaporate a fogging solution, which is then sprayed out as fog. Thermal foggers have a heated barrel that is prepared to high temperatures using propane gas or electricity. The fogging solution is a liquid that is rapidly evaporated when it is pumped into the heated barrel.

These mini fogging machines have the benefit of creating smaller particles than ULV foggers, and the fog is also more visible, making them ideal for applications such as insect and mosquito control. The thermal fogger can get into tight spaces like floor gaps, wall crevices, and similar areas indoors, as well as thick shrubs, long grass, high treetops, and other difficult-to-reach outside areas.

They can be used to spray fungicides, pesticides, poultry vaccines, disinfectants, miticides, and odor neutralizers that are both oil and water-based. It burns the pesticide and creates a fog that helps to kill the insects in the area.

Thermal foggers are highly effective when the air blow is quite still. It may be mounted on vehicles for outdoor use and is especially useful for bigger areas because it provides quick and effective management.

These machines are fuel-powered and come with an electrical automatic start-up igniter that requires only a finger press to start the machine. In addition, it has an automatic cutoff feature that ensures the user's safety by stopping the flames from being sprayed instantly if an accident occurs. These small fogging machines are simple to operate and maintain.

  • Cold fogging machine

Also called ULV (ultra-low volume) foggers, these machines use pressure to create fog in one of two ways. The solution is either forced through a high-pressure nozzle or is slowly passed through a vortex of high-speed air. The liquid is broken up into small droplets by the pressure, which subsequently sprays out as a low-volume fog.

It is powered by electricity and is used for farm disinfection, plant protection, pest control, and other purposes. It is precisely fitted with adjustable flow regulators to better control the rate of flow and fog droplet size. Some of them are self-contained; you can set the timer, and it will spray as needed.

Cold fogging machines also come in small and compact sizes, making them ideal for spraying in tight locations, such as in the garden to eliminate plant pests and in greenhouses to manage the disease. It's ideal for spraying while moving and can help you save a lot of money on the workforce. ULV foggers are frequently used to disinfect homes and huge warehouses and manage odors in these environments.

Steps for using a fogging machine:

  • The first step is always obtaining the chemical(s) to be applied using the fogger.
  • The second step is to mix or dilute the chemicals according to the instructions.
  • You may need to wear protective clothing from this stage.
  • The chemical is then transferred to the fogger machine. For this purpose, certain foggers are equipped with transfer bottles.
  • Connect the machine to the power switch after you have finished transferring the chemical.
  • After that, you turn on the power and (in most cases) wait for the appropriate indicator light to illuminate.
  • The machine begins to emit fog/smoke as soon as it is turned on.
  • If you are the fogger machine indoors, you will need to get out and close all of the doors and windows.
  • Then sit back and wait for the fogging to finish (and for the chemical to work).
  • You can then open the doors and windows.
  • It is critical to clean the fogger after each use.
