The French Air-in-Space Plasmair mobile air decontamination system, sold and supported in the UK by infection control specialist Tristel, is a self-contained unit that combines microbial destruction with fast airflow kinetics for environmental decontamination. The Snailwell, Cambridgeshire firm says the unit eliminates 99.999% of microbes in a single pass.
The Plasmair mobile air decontamination unit inactivates, destroys and eliminates a spectrum of airborne molecular compounds and micro-organisms
The UK’s Health Protection Agency at Porton Down Laboratories and the Harvard School of Public Health in the US have validated the efficiency of the HEPA-MD (High Efficiency Particulate Arrestance – Microbial Destruction) reactor at the heart of the system.
Originally developed for use in the MIR and ISS space stations, the Plasmair unit inactivates, destroys and eliminates a spectrum of airborne molecular compounds and micro-organisms including fungi, bacteria, viruses and spores.
The unit operates in three stages: first airborne micro-organisms are exposed to strong electric fields and oxidative species in unique non-thermal plasma chambers; then electrically active media for complete decontamination capture the highly charged materials exiting these chambers; finally airborne molecular compounds are eliminated in a catalytic converter.
The Plasmair unit is capable of abating up to 90% of airborne contamination from a 60m³ room in as little as 20min. Consistent particulate and biological targets of less than 10CFU/m³ – equivalent to ISO 7 using the ISO 14644-1 cleanroom standards – are achieved, says the company.
