Cartridge Filter System

Cartridge Filter System, a revolutionary concept, changed the way filter systems performed. The usual limitations to the filtration efficiencies offered by conventional bag filter systems and the related maintenance problems suddenly vanished. SANTONI was the first to introduce Cartridge Air Filters technology into India. While assimilating this state-of-the-art technology special care was given to the Indian conditions and the specific requirements of the industry. Santoni is also renowned among the most famed Industrial Cartridge Filters Manufacturers in India. Some of the benefits offered by SANTONI̢۪s Cartridge Filter Systems are outlined below: Compared to a conventional bag filter that offers a maximum of 99% efficiency for particle range down to 7 microns, cartridge filter systems can filter up to 99.97% down to 1 micron. (Now we have cartridges which can filter down to 0.3 microns too). Cartridge Elements in a cartridge filter system are built out of fine paper filter media arranged in a pleated manner, due to which a very large filter area is accommodated in a very small cylindrical shape. The net effect is that a cartridge filter system occupies much smaller area and space compared to a conventional bag filter system. Typically the space required for a cartridge filter system is about one eighth the volume required by a bag filter system. The architecture of the cartridge filter system is designed in such a way that servicing or replacement of filters takes just a few minutes and can be carried out by one person, unlike a bag filter system which requires up to several days to open and replace filters. The cartridge filter systems are offered by SANTONI in two configurations - horizontal and vertical. The "Gravityflo" downward air movement within the filter system allows natural gravity separation of the dust from the air and the downward air pattern pushes the dust down into the collection hopper rather than letting it go towards the filters. This reduces the filter loading considerably. The dust dislodged by the reverse pulse filter cleaning system is also pushed down. This obviates re-entrainment of the dust into the filters. The filters are continuously cleaned with reverse air blasts controlled by an electronic sequential controller. The filter system remains continuously operative at its peak efficiency. The typical life span of the cartridge filters is two to two and half times the bag filters. It makes the cartridge filter systems far more economical too. APPLICATIONS Cartridge Filter Systems (CFS) have several applications - such as,

• Dust collection, pneumatic conveying, central vacuum cleaning systems, etc.
• Because of their capability to provide exceptionally high degree of filtration CFSs are of particular use where toxic materials or materials of high value (e.g. gold dust) are handled.
• In the industries where cleanliness of high order is expected (e.g. clean room applications), CFSs are used in the dust collections and pneumatic conveying applications.
• In the tissue culture, aquaculture, pharmaceutical, chemical, pesticide, premium sugar, decorative laminates, printed circuit boards, diffusion labs, etc. the dust has to be eliminated and only CFSs meet the requirement.
• For powder coating paints - in their manufacturing or painting process - CFSs are very useful. After pulverizing in a mill the powder paint has to be removed and collected pneumatically, at the end of which a CFS can collect all the paint. Similarly, paint can be recovered efficiently in the painting process. A special benefit that CFSs offer is the quick change-over when the color is to be changed.
• Similarly, in the pesticides industry, toxic materials are pulverized which should be handled only with the help of CFSs, to prevent pollution of environment and exposure of the workers with the toxic materials.
• In the coated paper industry, where high quality paper is manufactured, presence of dust in the environment can be detrimental to the quality of the end product. Collection of dust from the buff rolls (cotton bowls) with cartridge filter systems prevents re-entrainment of the dust into the atmosphere.
• In the nut shell it will be worthwhile to say that cartridge filter systems offer greater filtration efficiency, at reduced cost and, therefore, are a better choice where the dust has to be completely removed or recovered.
