A Cartridge Dust Collector uses perforated metal cartridges that are cylindrical shaped and open on one or both ends lined with a pleated nonwoven filtering media. Once installed, one end of the cartridge is sealed off and the open end is used for the clean exhaust. Similar to a Baghouse, the Gas stream is forced through the outside of the cartridge to the inside where it then exits back into the system. Cartridge Collectors are also compatible with Reverse or Pulse Jet cleaning. Large numbers of these Collectors can be installed and used for continuous filtration for a location’s Dust Collection system, such as during Asphalt production.
While no long as widely employed as they once were, Cartridge Dust Collectors are uniquely suited for certain applications involving certain special shaped and sized dusts (granular shaped & less than 50 microns) and low grain loading levels (less than 5 grains per cubic foot). Certain dusts require minimal flexing of the media during the cleaning process; thus, Cartridge Collectors will perform satisfactory in these applications. Uses include but are not limited to: Grinding or Sandblast applications, Welding fumes, laser and plasma cutter fumes, Graphite, Pharmaceutical and fine Chemical Powders.
Increasingly cartridge collectors are being replaced with the latest generation of pleated filter elements as they combine many of the benefits of cartridge units with the benefits of baghouse technology. They also easily are retrofitted into existing baghouses and are more easily produced.
