Portable fast disinfection device. The unique Counterfog® SDR-F05A+ provides a powerful fog cone made of submicrometric droplets of liquid biocide. Due to the nano-size and the penetrating ability of the cone, it fastly removes from air all kind of chemical, biological, radiological, aerosol, smoke, and dust contamination. Most biocides are compatible to quickly kill microorganisms like bacteria, fungi or virus both in air and on surfaces.

Counterfog® action reaches all intricated holes and spaces and kills the most resistant microorganisms. It can be used to sanitize, disinfect or sterilize facilities or vehicles in a few minutes.

For example, application of Counterfog® SDR-F05A+ with Hydrogen peroxide in a 20 m³ room just for 1 min ensures that the most resistant Bacillae spores and non-enveloped virus are inactivated. Suitable for all kind of biocides (hydrogen peroxide, sodium hypochlorite, etc.) (Warning: Not recommended for flammable liquids -like alcohols- . Please consult this case.)

Conventional physical cleaning and disinfection procedures like spraying or wiping tend to resuspend micron-sized particles and dust which escape disinfection. COUNTERFOG ® is the only technology that fights efficiently in the submicrometric range due to 2 key properties:  NANOMETRIC SIZE   and   DYNAMIC AGGREGATION.

DROPLET SIZE:  COUNTERFOG® droplets main size: 40 nanometers as measured by INTA.

DYNAMIC AGGREGATION: COUNTERFOG® cone provides unique aggregation dynamics that capture and collapse particulate matter, bioaerosols, etc.

The portable SDR-F05A+ is specially designed for the neutralization of volatile and respiratory Chemical, Biological, Radiological or Nuclear agents in facilities, industries, hotels, hospitals, homes and vehicles.  In particular it is the ideal tool to fight air-borne and volatile pathogens like Anthrax, Tuberculosis or SARS-CoV virus.

It can be easily operated by one person. The level of microorganisms reduction will essentially depend on the biocide and application rate.

The patented Counterfog® technology is unique removing gases (like SO2), vapors, airborne particulate matter, fine and ultrafine aerosols, smoke and dust from air.

It is the fastest system to disinfect any space. It even disinfects the most hidden and intricate holes, places and surfaces. Additionally the amount of liquid biocide used is really scarce.  Unlike all other disinfection technologies the recovery time after application lasts just a few minutes. And it is completely environment-friendly. It can be applied on clothes as well.

It provides a film of liquid only a few tens of nanometers thick -just enough to kill microorganisms but with a minimal side-effects. Therefore, no subsequent drying is necessary, as it does not wet surfaces. Moreover, it is quite suitable for most delicate surfaces, such as electronic devices, documents, artworks, furniture, etc. Evenmore, its powerful suctioning air swirl draws any volatile pathogen from air. It does not damage objects, artworks or furniture. Please contact us for more details on application on artworks.
