Filter Cartridge Support Core (Custom to cartridge design) is specified where the duty calls for giving pleated air and liquid filter cartridges their inner strength with spiral-seam perforated or expanded metal cores that resist collapse under pulse cleaning and pressure. The sections below cover the typical end-uses by industry, the mesh, micron and material decisions for each, installation practice, and the applications this product type is not suited to.
Typical Applications for Filter Cartridge Support Core
Where Filter Cartridge Support Core is specified and bought:
- Dust collector cartridges: inner cores for pulse-jet cartridges.
- Gas turbine intake filters: cores for high-flow cartridges.
- Liquid cartridge makers: support tubes inside pleated elements.
- Filter OEMs: cut-to-length core supply.
How to Specify Filter Cartridge Support Core for Your Application
- Diameter & length: Match the cartridge design.
- Perforation: Round holes or diamond expanded mesh with high open area.
- Material: Galvanized steel for air; stainless for wet or corrosive duty.
- Standard: Quote Custom to cartridge design and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Deburr ends so the core cannot cut the media during potting.
- Store dry to avoid white rust.
Common Selection Mistakes with Filter Cartridge Support Core
- Sharp edges that cut pleats.
- Too weak a core that collapses during pulse cleaning.
Where Filter Cartridge Support Core Is Not the Right Choice
Not a filter medium.
