Mobile fogging

SNP supplies a wide range of equipment for the distribution of fogs and fine mists for disinfection and sanitising.  The fogs generated by this equipment are very different in nature to the fluid distributed by cleaning/washdown systems and foaming systems. 

The objective with any fogging system is to maximise the coverage of the disinfecting chemicals and ensure they come into contact with as much of the airspace and surfaces being treated as possible.  This is best achieved by finely atomised sprays which will remain aerosolised for longer periods of time.

The effective distribution of fogs and mists is a significant problem to overcome.  By their very nature, fogs do not have a lot of natural momentum.  For this reason, the use of compressed air or fan-induced air flows is a common feature in our fogging systems.  Not only does the fast moving air help atomise the disinfectant, it also helps distribute it over a wider area.

Compressed air fogging guns

Disinfectant fogging guns operate with compressed air.  Air is passed through the gun and it entrains a low volume of liquid from the integrated container.  This then forms a low volume, well atomised fog which is ejected from the gun.  The gun is controlled by a simple trigger valve.

With our range of Lafferty fogging guns, dosing rates can be controlled via the insertion of different restrictors into the siphon tube.  This allows for flow rates between 1 litre per hour and 23 litres per hour to be achieved from the same gun. 

The fog produced by these guns is still a damp fog, rather than a dry one so care needs to be taken when using around electrical equipment and other surfaces that cannot tolerate wetting.  Also, full PPE should be worn by the operator and careful attention given to the safety instructions on safe usage of the disinfectant being applied.

Air-assisted fogging stations

These machines can be permanently installed in a room or on a wheel-mounted mobile unit.  They use compressed air and can project fog up to 7.5m.
