String Wound Filter Cartridges

Shelco Filters has created the MicroSentry wound cartridge, setting a higher standard for industries requiring cartridge filtration. Our equipment makes achieving precision patterns a matter of standard procedure. Our state of the art computerized production machinery takes the variables out of custom winding, and enables us to produce filter cartridges that are accurately wound from a single strand of specially selected fibrous roving material, wound around a perforated core in a nearly perfect geometric pattern.

MicroSentry wound cartridges can be produced from a wide range of materials. With a range of 0.5-150 microns filtration, depending on your requirement for removal of solids from liquids, compressed air or gases. The MicroSentry Cartridges are independently tested to have the highest efficiencies in the industry.
