Component Specifications

Definition
The core tube is the central cylindrical component within a filter cartridge that provides structural support to the filtration media (such as pleated paper, mesh, or synthetic fibers). It maintains the media's shape and spacing during operation, prevents collapse under pressure differentials, and serves as the central channel for filtered fluid collection and discharge. Core tubes feature precise perforation patterns to optimize flow distribution while retaining media particles.
Working Principle
Acts as a rigid backbone for the filtration media, allowing fluid to pass through the media into the central channel while supporting the media against pressure forces. The perforated design creates uniform flow paths and prevents media deformation.
Materials
Typically made from polypropylene (PP), stainless steel (304/316), galvanized steel, or aluminum. Material selection depends on chemical compatibility, temperature range, and pressure requirements.
Technical Parameters
  • Length 250-1000 mm
  • Outer Diameter 25-150 mm
  • Wall Thickness 1-3 mm

  • Perforation Size 1-6 mm
  • Temperature Range -20°C to 120°C
Standards
ISO 2941, ISO 3724, DIN 24550

Frequently Asked Questions

What is the purpose of perforations in a core tube?

Perforations allow filtered fluid to enter the central channel while maintaining structural integrity and preventing media bypass.

Can core tubes be reused after media replacement?

Yes, if undamaged and properly cleaned, core tubes are typically reusable with new filtration media.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
