Star-pleated Filtration Group dust filter cartridges are used to sep- arate very fine particles from gases. The gas flows inward through the cartridge and is discharged via the open end cap on the top. In combination with the Filtration Group MJD cleaning unit (pressure cleaning with a multi-jet nozzle), this filter cartridge provides an ef- ficient solution in exceptionally challenging environments. This is also supported by a special method of element pleat stabilisation. Regular, extensive material and performance tests are the key to the consistently high quality of Filtration Group dust cartridges. A team of dedicated engineers in our applications department and modern development laboratories constantly endeavour to mature and perfect our products. Applications tests both on the customer ́s side and in our own facilities form the backbone of affortable and reliable products.
