Support Core: Temperature Range -20°C to 120°C

Component Specifications

Definition

The Support Core is a cylindrical or multi-lobed structural element within separation cartridges and filtration systems that serves as the central backbone. It maintains the geometric integrity of pleated or wound filtration media, prevents collapse under pressure differentials, and ensures uniform flow distribution across the filter surface. Typically manufactured with precision tolerances, it interfaces with end caps and housings to create sealed filtration assemblies.

Working Principle

The Support Core operates by providing radial and axial structural support to filtration media, resisting compressive forces from fluid pressure and mechanical loads. It maintains consistent spacing between media layers, prevents channeling or bypass, and allows filtered fluid to flow through its perforated or slotted structure toward the outlet. Its design ensures minimal pressure drop while maximizing filtration efficiency and media utilization.

Materials

Stainless steel (304, 316L), polypropylene, ABS plastic, or aluminum, selected based on chemical compatibility, temperature range, and pressure requirements.
