An electric fogger is a machine that uses electrically powered airflow to break liquid into extremely fine droplets, typically between 5 and 50 microns in diameter, and disperse them as a mist. These devices are used for pest control, disinfection, mold remediation, and odor treatment in both residential and commercial settings. They’re sometimes called ULV (ultra-low volume) cold foggers because they rely on air pressure rather than heat to create the fog.
How an Electric Fogger Works
The core components are simple: a tank that holds your liquid solution, a blower powered by an electric motor, and a specialized nozzle. The blower forces air through the nozzle at low pressure, and the liquid from the tank is fed into that airstream. Inside the nozzle, small fins cause the air to
