The efficiency of any Carbon Air Filter is directly related to the quality of carbon media used; the quality of the cartridge casing; and the loading technique adopted, with the added proviso of an even air flow through the cabinet and many other specifications. It's better for those who are considering buying carbon filter to know some knowledge about carbon filter specifications at first. Now let's get to know these important carbon filter specifications.
First of all, the MEDIA of carbon filter. What carbon filter used is the carbon which is carefully sourced. Then the active carbon media is prepared in small batch quantities by the addition of thoroughly researched additives. Granular activated carbon media is most commonly produced by grinding the raw material, adding a suitable binder to give it hardness, re-compacting and crushing to the correct size. The large internal surface area of carbon has many attractive forces that work to attract other molecules. The carbon media is then tested to ensure that all filters will achieve their optimum retention capacity.
The second carbon filter specification is CASINGS. Filter casings are manufactured from reinforced thermoplastic. This ensures that the weight is minimal for ease of handling and installation, whilst providing very high impact strength, excellent dimensional stability and chemical resistance. This is the maximum liquid flow for which the filter is designed. Filtration grade describes the ability of a fluid filter to remove contaminants by particle size. Machinery manufacturers may accept the Beta ratio, but refrain from using this information to identify or specify their filters. Final stage is the third carbon filter specification. The casing is filled, tightly packed, so no settling can occur during shipment and the weight of each filter is checked and recorded. If the cabinet that the filter is destined for requires a pre-filter, then this will be added at this stage. The maximum liquid flow for carbon filter is designed. Maximum temperature of carbon filter is designed too.
Last but not least, the working performance is one of carbon filter specifications. Carbon Filters are shown to provide a filtration efficiency of 99.9% throughout their life to the point of saturation, for all chemically active molecules/chemical species. This includes any chemicals with a molecular weight above 30 and a boiling point above 60oC. Some compounds, which do not fall into this bracket, are also well adsorbed because of their molecular size and structure. Before buying carbon filters, these carbon filter specifications must be taken into consideration.
