How do the ULV Cold Foggers work?
ULV foggers work on the principle of Bernoulli's theorem. The Electric Motor generates a high volume of air and is directed through a specially designed aerodynamic housing to give a resistance free flow to air and accelerate the velocity, a stream of air pumps up the air in the fluid tank which pushes the fluid towards the speciaal nozzle which houses a air diffuser which when coupled with the high velocity stream of air, atomizes the fluid. ULV Cold Foggers work on electricity.
Placing a tank below the motor avoids leakage and performs better.
ULV foggers have a regulator to control the droplet size, which can be achieved by changing the flow rate of fluid from the tank to the air diffuser. These particles when sprayed indoors stay in air for a longer time and can reach smaller gaps and holes in the walls and floor as well as spaces behind furniture and other tight spaces. It does not wet the surface and equipment.
These suspended particles act on virus and bacteria, as specified by the fluid manufacturer. These machines can even be used for deodorising and keeping the mosquitoes away by spraying insecticide.
