    What Is A Disinfectant Fogger Machine

    A disinfectant fogger is mainly composed of tank, nozzle, motor and hose. It is a machine that uses a fine spray to turn a chemical solution into a mist vapor which can be used for disinfecting or restricting the growth of mould, viruses, and bacteria. Such device allows chemical solutions to be easily and rapidly applied to large spaces, which can effectively resist pathogens, especially pathogens that are airborne or carried in respiratory droplets, such as influenza virus or COVID-19 coronavirus.

    How Fogger Machine Work?

    All fog machines work by filling the spaces with a solution of disinfectant properties. There are a variety of sterilizing fogging machines on the market that provide different types of fogging treatment. Of course, the operation is very simple. Add solution to tank, turn on the switch, then the fine-mist droplets will spray into the outer space and kill the viruses you want to disinfect.

    Types Of Disinfectant Fogger Machine

    There are two primary types of fogging equipment devices available: thermal foggers and ULV (Ultra Low Volume) foggers, also known as "cold foggers".

    A cold or ULV fogger uses high-pressure of air to transform and spray the solution into tiny particles. There is an electric motor inside its body. This determines the power of airflow which converts the pesticide into small particles. Most cold foggers are designed for water-based solutions, but some may also use water and oil-based pesticides simultaneously.

    A thermal fogger, by contrast, uses heat to vaporize the fogging solution creating a fog or cloud that penetrates hard to reach areas. It generally uses a 40-ounce solution tank and takes the pre-heating process for 2 to 5 minutes. Once it is ready, you can simply unlock the trigger if any, or just pull the trigger to transfers the solution to a heat assembly on the front of the device.

    Each type of equipment has its benefits and disadvantages. Just view the tables below.

    Factors To Consider When Deciding On A Disinfectant Fogger

    • Easy to use. Do you have to take much time to assemble the fogger device or to learn how to operate it? These is a question to consider.
    • Cost. Fog machines start at less than $150 and can reach $400 and much more. The upper range includes more powerful machines with a number of better build quality, and more watts to fog a larger area. Ongoing costs for fog machines include fog juice, cleaning fluid, and the power necessary to run them. You should choose the product reasonably according to the spaces you use within the price range you can afford.
    • Warranty. As the machine is a frequent used item (especially during high incidence of infectious diseases), it is prone to wear and tear, so it is important to choose a manufacturer offer a warranty and good after-sales service.
    • Cordless or corded. There is no way to use a cord fogger in some complex environments or spaces without electrical plugs, then you have to choose a cordless fogger. When choose a cord fogger, please take a look at the length of the power cord to make sure whether it is long enough for the space you disinfect.
    • Spray range. This is a factor that must be paid attention to as it decides whether it can santilize the area you want.
    • Flow Rate. It is the measure of the volume of solution that moves in a certain amount of time, which decides whether your disinfection work is more efficient. The rate is usually range from 400ML / min to 750ML / min or higher. The higher the flow rate the fogger is, the more time you will save during the disinfection work.
    • Wattage. Please buy the highest wattage fog machine you can afford which makes the disinfecting more effective. As this will give you more options in terms of where you can use it and cut down on the risk of producing an underwhelming “thin” fog effect.
