SLS air decontamination unit filters and destroys pathogens

Published: 21-Oct-2008

An air sterilisation and decontamination system that uses close-coupled field technology (CCFT) to filter and kill harmful particulates has been launched by Scientific Laboratory Supplies (SLS).


The Air Manager system uses an electrically generated plasma field to sterilise the passing atmosphere, filter out airborne pathogens and destroys them.

It works by drawing air into the unit via a fan system, which passes through and around the CCFT. The electric charge from the particulates that enter the fan interferes with the plasma field. This results in a break down of the chemical bonds and reduces the particulates to their elemental constituents.

Heavier elemental constituents, which can be harmful, are generated by the breakdown of CO2 in the atmosphere and are then removed by the combination of the CCFT and the charged exhaust filter bed. Because CCFT technology ensures total destruction of airborne contamination, these systems are not reliant upon filtration alone and this reduces the chances of failure compared to HEPA or other conventional methods. Furthermore, they not only perform a key role in reducing the chances of contamination, they also contribute toward significant cost savings. For example, savings on expensive plate stocks, due to the reduction of test failure rates and the removal of T4 Phage contaminants helps to protect glycerol stocks of bacterial cultures and so avoids expensive losses. Also, removal of odours and chemical fumes means enhanced protection and comfort for staff and contributes to a safer, more pleasant working environment.

Air Manager units are available in a range of options, including wall, ceiling and table mountable.

Applications for the Air Manager system are numerous and include, laboratories experiencing any level of failure in plate testing or tissue culture, facilities with an autoclave for odour reduction, universities where teaching inexperienced handlers of pathogenic material can cause increased risk of infection, pathology and clinical departments in hospitals where contamination risks are highlighted for MRSA.
