Filter Cartridge Support Core in 304 Stainless Steel (AISI 304 (1.4301)) is used 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 alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Filter Cartridge Support Core Is Used
- 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.
Ordering Filter Cartridge Support Core in 304 Stainless Steel
- 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.
Mistakes to Avoid with Filter Cartridge Support Core
- Sharp edges that cut pleats.
- Too weak a core that collapses during pulse cleaning.
