The Purazone has two speed settings to
maximise kill rates:
Normal @
14.5 Litres Per Second
Fast @
18.5 Litres Per Second
All Kill Rates shown below
are greater than >99.999% at one pass through the Purazone.

For Example:
Use normal speed in barrier
nursing, offices and bedrooms up
to 15 x 10 x 8
Use fast speed in waiting
areas, lounges and doctors receptions up to 25 x 15 x 8
All Kill Rates also showed
no sign of mutation or regrowth of organisms in incubator 5 days
after tests.
Organisms tested included
the bacteria:
E.Coli 157, Salmonella
Typhi Murium, Staphylococcus Aureus MRSA, Streptococcusfaecalis,
mould including aspergillus niger. The optimum speeds are 14.5 and
18.5 litres per second after this the kill rate will reduce pro
rata.
CONCLUSION
(TAKEN FROM MICROSEARCH DOCUMENT)
The Purazone device performed
impressively during single pass challenge trials with all catagories
of micro-organism employed in the trials. Further, no deficiencies
in performance were detected during field trials and on this basis,
the device can be recommended as an important tool in the maintenance
of Sanitary Enviroments.
