Appendix 4 for calibration and testing CLEAN AIR LTD 8 8 2 8 4 FILTER TYPES amp MONITORING Pre Filters Filtrete pre filter This is a high performance pre filter designed to remove particulates from the airstream The filter material is based on electrets which are permanently changed dielectrics They remove particulates from polluted air by strong electrostatic forces generated by the fibres from which they are made The combination of a strong electric charge and open structure provides a filter with high efficiency low airflow resistance and high loading capacity Measured efficiency figures for particles in the 0 5 2 0 micron range is 99 with loading capacities up to 113g m squared Filtrete will remove fine particles aerosols mists smoke and dust Main Filters CA SCHOOL Filter The CA SCHOOL filter has been specially formulated to absorb the normal range of chemical fumes generated in Schools during GCSE and A Level classes Monitoring If the pre filters are blocked the airflow willbe reduced at the fume cupboard aperture If the main filters are saturated they will cease to remove the fumes effectively The Fume Cupboards are fitted with 1 A low airflow alarm Dy A filter saturation detector 3 An on off power switch If an odour is noticed it is sensible to check the fume cupboard However it must be remembered that the sense of smell is very sensitive f
