MAIN FILTERS
Three types of filter media are available.
Most of these are impregnated activated charcoal, to provide a higher filter capacity for lower molecular
weight organic compounds and inorganic gases and vapours.
A number of filter efficiency studies have been carried out and all results using single bed filters show
efficiencies very close to 100%.
1. A/C FILTER
The A/C filter is the most widely used filtering the range and is used primarily for solvent fume removal. It is
manufactured from coco-nut shell based activated charcoal of 4 x 8 USS mesh size and surface area up to
1050m2/gm.
Filtration is achieved by the physical adsorption of molecules in the pores of the activated charcoal by Van
der Waals forces.
2. ACR FILTER
This filter is impregnated with halide salts and is used for the high efficiency removal of iodine and methyl
iodine. It is frequently used for iodination reactions with low-level radioactive iodine and efficiencies in
excess of 99.99% have been measured
3.
FORM FILTER
This filter is impregnated with an oxidizing agent to oxidize formaldehyde to formate salts.
It is widely used in hospital pathology laboratories and suitable for use with formalin, gluteraldehyde and
aldehydes in general.
