Fogging , Dry fog and Evaporation for disinfection

Disinfectant can be used in different state for killing bacteria , viruses and fungus. 

For a long time we have used only the liquid state of disinfectant by wiping and spraying .This is the easy , low cost  way for surface disinfection , it is effective against the pathogens on the surface .But there are some limits of this conventional disinfection method ( the effective disinfection process is done by the liquid disinfectant  ) :

Coverage rate :  As spraying and wiping are all made manually , apart of some difficul reaching areas , people can cover 70% surfaces exposed , so there are always some undisinfected areas left after the disinfection work . 

No air disinfection : A conventional disinfection method is not effective for the air disinfection , even though a super fine fog spray gun is used . Because the particles created by a spray gun fall down on the surface for gravity . 

High corrosive : No matter wiping or spraying (considerated as fogging ) , the principle of disinfection is that liquid disinfectant solution contact the surface for a certain time meanwhile killing the pathogens on the surface . If the disinfectant is corrosive to alluminium  ,  after a certain time the alluminium surface will be corroded .

What are the difference between Fogging , Dry fog and Evaporation for disinfection ?

Normally Fogging , Dry fog and Evaporation are defined by the diameter of particles generated , but there is not accredeted international normative , particularly for the disinfection industry . 

In the chinese disinfection industry the particle sizes are recognized like this : 

Fogging :  >25 micron .

Dry mist ( dry fog ) : 0.5-25 micron .

Evaportation : molecule size 

In our opinion of view ,  we should classify by the result and purpose in disinfectin industry . Because the dry fog and Evaporation technology are developed for increasing the coverage rate and disinfection efficiency ( consumption per cubic meter )  and reducing corrosion , these are the result and purpose in the disinfection industry .

So we prefer to classify fogging , dry mist and Evaporation as following :

Fogging : After disinfection cycle , surfaces get wet of disinfectant solution , max air biological decontamination is achieve 90 % , there are dead angles on the exposed surface such as the back surface of a desk

Dry mist ( dry fog ) : After disinfection cycle , no surfaces get wet of disinfectant solution , max air biological decontamination is 99 % , there is no dead angles on the exposed surface exposed , but inside the closed but not sealed space as  drawer,   the disinfection efficiency is much lower than outside

Evaportation : After disinfection cycle , no surfaces get wet of disinfectant solution , air biological decontamination rate can achieve 99.99 % , there is no dead angles on the exposed surface exposed , even inside the closed but not sealed space as  drawer,  the disinfection efficiency is not affected

Fogging , Dry mist and Evaporation all in one technology by Fasfrede

FasFreDe system ,  disinfectant is atomized with a unique and proprietary system, using a mix of pressure, air speed, temperature and expanding surface , which allow a capacity to vaporize at the nanometric level and distribute it with the air flow of 80m/s evenly over the entire surface and air to deal. The atomization level allows to create gasified disinfectant particles at molecules (0.4 nm) that do not release droplets and do not damage the equipment and surrounding material. Log 6 of pathogen reduction are guaranteed within 500 m3

By regulating the disinfectant supply quantity , air speed and temperature this system makes different atomization effect with the same mechanism

Fogging :  spray 1500 ml/h – 6000 ml disinfectant per hour , particles sprayed out from 25-150 micron .

Dry mist ( dry fog ) :spray 500 ml/h – 1500 ml disinfectant per hour , particles sprayed out from 0.5-25 micron .

Evaportation :spray 50 ml/h – 500 ml disinfectant per hour , particles sprayed out sub micron .
