Portable Decontamination Backpack DryFogger, PBDF-48-10um


Applied Physics provides a truly portable, battery operated, backpack dry fogger, which is properly designed for decontamination and disinfection of areas by generating a dry fog output with a fog droplet size of 10 microns. The dry fog emitted is composed of millions of 10 micron droplets and when mixed with FDA approved disinfecting liquid, purchased separately, the resulting sanitizing fog will evaporate to form a much larger vapor to kill on contact most unwanted bio-organisms, according to the specifications of the disinfecting liquid used.


This portable dry fogger provides a 10 micron fog, which allows the fog to float into the airflow, evaporate into a much larger, invisible, sanitizing vapor in order to contact every open surface and pathogens in the airflow and kill the unwanted bio-organisms. In order for proper decontamination with a dry fogger output, the Sauter Limit dictates that the droplet diameter must be 10-micron or less in order to allow for fog suspension. Droplets at 10 micron diameter are called a DRY FOG, as the droplets tend to float in to the airflow and evaporate to form much larger volume sanitizing due to low mass. Fog Sprayers are often sold, alluding to a large sanitizing vapor, but fog sprayers have an output of 50 to 70 micron diameter, which is to heavy when sprayed into the airflow, pulled down by gravity to simply WET a surface, making sprayers useless for sanitizing an area and its wall surfaces. DryFog droplets emitted by the BPDF back pack fogger generates 10 micron droplets. When mixing our disinfecting liquid into your pure water, the 10 micron liquid droplets that are created by the Dry Fogger, float into the airflow to evaporate and form an exponentially larger volume of sterilizing vapor. This vapor then comes in contact with accessible surfaces including walls, floors, carpets, curtains, light fixtures, wall switches, ceilings, under furniture, behind appliances, in-ceiling corners, under tables…open surfaces as well as the air molecules in that enclosed area, which carry viruses in that enclosed area.


This Dry Fogger method of dispersing a disinfecting vapor provides a far better solution to actually sterilizing an enclosed area, as opposed to spraying large droplets on the floors, walls and and corners. The Dry Fog vapor leaves no mass residue behind, thus is much safer for adults, children, and animals. When using a backpack portable dry fogger, you must choose the disinfecting liquid you wish to mix with your pure water source. When using a Dry Fogger, your water source must be as particle free as possible, so TAP water is not the right water to use due to the large particles found in everyday tap water. You want to choose the right disinfecting liquid to mix with your pure water, thus a powder disinfection mix can not be used. When using a backpack portable dry fogger, you want to use the right breathing protection, sufficient to protect your lungs from the vapor you are using to kill viruses. Use eye goggles to keep the vapor from your eyes.


Our Atomizing Fogging machines are cold fogging machines using high volumes of air at low pressure to convert water and sterilant into 10 micron droplets. The liquid droplets are then pushed into the atmosphere as a visible fog, which then evaporates. These decontamination foggers are used to create a visible sterilant fog using pesticides, herbicides, fungicides, sterilants, and disinfectants that evaporates from a visible fog to a large invisible vapor to contact and kill most unwanted pathogens in the room, depending on the effectiveness of the sterilant used.
