The choice of cartridge filter depends on the application.
Cartridge elements in a cartridge filter system are built out of fine 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 (one-eighth).
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 conventional bag filter system which requires up to several days to open and replace filters.
The dust dislodged by the reverse pulse jet cleaning system is 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.
In summary cartridge filter systems offer greater filtration efficiency at a reduced cost and therefore, are a better choice where the dust has to be completely removed or recovered. In many filtering applications, a choice between the use of a cartridge filter and a bag filter has to be made.
